Author Topic:   Verado 250 Fuel Consumption
ATF posted 09-25-2005 06:49 PM ET (US)   Profile for ATF   Send Email to ATF  
I am planning on buying twin 250 Verados on my 12,000 lb boat, but with today's fuel prices, I am concerned to how they compare to the rest of the market on fuel consumption. I am impressed with the performance and power of the Verado, but unlike most of it's competitors, Mercury doesn't offer any performance data. Does anyone have any real data that could shed some light on how closely the fuel consumption is between the top outboards? Thank you for any help.

You can find test data including fuel economy on whaler.com. Just click on the performance data icon on any of the larger boats. They only compare the Verado to the Optimax though.

Thanks, this is new information to me, but does anyone have any information comparing the Verado 250 to Suzuki, Evinrude, Yamaha, or Honda.

Fuel consumption rates from end to end (idle to WOT) for the Optimax, Evinrude E-TEC, Suzuki, Yamaha or Honda are very similar. Compared to all of those, the Verado is a guzzler above 4500 RPM. WOT fuel burn for the 250s is about 22 to 23 GPH, for the Verado it is in excess of 28 GPH! Wouldn't want have to run the Verado on the pins for very long.

Peter,
Would you say that the Verado is comparable to all of the other brands below 4500 RPM?

Yes, the data seems to show similar consumption rates until 4500 RPM then the rates diverge.

It seems that the Yamaha outboard website has the best access to reports of boat tests with fuel economy numbers for their engines. There are dozens of reports available for each model and horsepower. In contrast, the Mercury website seems to be devoid of this information.

There have been some magazine boat tests of the Verado. Some of these are available on-line. Powerboat Reports (PR) has tested the Verado twice in the past year or so.

In one test, PR declared the 250-HP Verado the winner, in spite of a $5,000 price disadvantage compared to an E-TEC or a Yamaha four-stroke. In another test comparing a 250-HP Verado and a Suzuki four-stroke, the Suzuki was the winner.

One problem with reports of fuel consumption on the Verado: the people at Powerboat Reports stated that in their measurements they used an external fuel flow meter to gauge the fuel flow on the other engines, but for the Verado they relied on its internal fuel flow meter. This is a flaw in the test technique. It is a basic requirement that if you measure something, you ought to use the same measuring instrument on all the tests.

Above about 4,000 RPM the fuel consumption of the Verado increases compared to the naturally aspirated four-strokes.

One does not need a degree in mechanical engineering to grasp the fact that the energy to drive a supercharger, which is considerable, comes from burning fuel, and hence there is no way that supercharged engines are going to be top performers in the fuel economy stakes once their superchargers are really pumping. Rather, they will be top performers in terms of horsepower per liter of engine displacement, which is hardly an advantage meaningful to recreational boaters. If a smaller engine displacement led to a lighter and more compact outboard, there would be some basis for a trade-off. However, Verados are heavier than other 4-strokes and considerably bulkier and about 20% heavier than Evinrude E-Tec direct injected 2-strokes. For these reasons, one wonders why Brunswick went down the Verado development path. Nevertheless, they are certainly fine pieces of engineering and are proving to be mechanically robust and amazingly quiet. For many boats, extra weight on the stern doesn't matter much.
However, fuel consumption comparison tests have shown that Verados are remarkably economical between 1500 rpm and 4500 rpm, and some comparative tests have the Verados as fuel economy winner, albeit at a lower boat speed than competing motors have as their most economical speeds. One such test was published recently in the Swedish magazine "Båtnytt" -- the test data were posted on "The Hull Truth" forum.

In response to wondering, I think Brunswick went down the supercharger path in order to gain the 2-stroke acceleration and response performance that they anticipated would be attractive to buyers, especially performance minded buyers, and as 2-strokes disappear. This is proving to be correct, and generally, performance minded buyers don't care much about fine tuning economy at wide open throttle. They just want to win and go fast! The other thing the supercharger gives is the ability to get more HP out of an engine, when the time comes. Everyone I have talked to who has driven a Verado raves about it.

Do we really think a 2.6 liter Verado can only put out 275HP? Can a 1.7 liter Verado put out more than 175 HP?
How easy is it to add cubes and HP. Almost every manufacturer begins at smaller cubes, and then increases them on same block. These things have real potential.

I think the 4-stroke buyers are not interested in super quiet running and performance will continue to buy the Japanese products. Are the Japanese companies working on supercharging, incidentally?
Anybody know? I can't imagine they'd go so low as to copy Mercury.

Verados have already captured the attention of other brand boaters, even if they publically don't like them. When you see a Verado powered boat, everybody comes around and looks, and with their premium pricing, everybody knows this is a guy who can afford the best. At the Whaler events, everyone wnats to try out the Verado powered boats, not the Optimax powered boats, as they are considered old school now

The marketing department has done a nice job of creating the illusion that the Verado is a performance motor, but as soon as you look at the numbers that the Verado puts up, they are not indicative of a performance motor. Rather, what those numbers show is a motor that is up to 25 percent heavier and consumes up to 30 percent more fuel to make its rated HP than the competition. That is not any way to win races. In races, light weight and fuel efficiency matter. The Verado should really be thought of as a moderate speed cruising motor with creature comforts at best.

If it were so easy to add HP to the Verado platform, why didn't they just come out with a 525 lb 250 HP 4-cylinder Verado right from the start. If they had done that, they might have had something worth talking about in terms of performance. If they turned up the boost on the 4-cylinder Verados to achieve 250 HP, where would that leave all of the early adopters of the 6 cylinder versions? Why would Brunswick go through all the trouble of redesigning their boats to accomodate the extra weight?

All outboard motor manufacturers, except for Mercury, seem to adhere to the age old notion that there is "no replacement for displacement". Suzuki had an opportunity to go the supercharged route with its new 150/175s and it opted for displacement. I wonder why? Supercharging certainly isn't necessary for either 2 or 4-stroke outboards that have sufficient displacement. These motors are not used in stop and go traffic.

Interestingly, the things that people rave about on the Verado (DTS and power steering) really have nothing to do with the Verado outboard. I tend to think that people look at the Verados because they can't believe how big they are compared to what they are used to seeing on the transom.

Verado has captured the attention and everybody comes around to see them because you just don't see them around. As much as I looked this summer on the Great Lakes(Michigan & Erie) I haven't seen one privately owned Verado. I tend to cruise with my E-TEC at 4500rpm and above and fuel consumption is great. The 28gph of the Verado is excessive to say the least. I think the extra weight they carry will hurt them especially with the Bass Boat people. Even with the supercharger they can't beat the acceleration of the E-TEC. The Suzuki engines are indeed making an impression with boaters.

Well, I certainly agree with that to a certain degree, but I'm not so sure that it translates into a solid marketing strategy. Afterall, everyone would want to test drive a Maybach, or a Lotus, or a Ferrari if that were available to them at an auto show, but I don't see any of those companies selling a lot of vehicles. As for being "the guy that can afford the best" - well I guess that attitude does come with owning a Whaler too...

"performance minded buyers don't care much about fine tuning economy at wide open throttle. They just want to win and go fast"

True too, but hey, boating isn't all about performance - not for the majority of the boat buying public. Again, that mindset is going down this narrow market path, and a strong argument can be made (dependent on what type of racing is done) that it's not the winner in all kinds of races - especially where fuel usage might be a factor.

I'm not bashing Verado - I like it. I just think that a lot of what Mercury has been doing is performance minded - it goes with their strong heritage for performance. We Americans scratch our heads sometimes about this because everything is a pissing contest.

But a strong wind is blowing on the fuel price front. And much of the "economy" arguments and marketing is carrying over strongly from the automobile industry. True, most who can afford a Verado aren't affected by this as much, but by the time you're a teenager, most guys have figured out that it's tough to pee into the wind....

The trouble is that Mercury should have developed a competitive engine at a similar displacement/weight as the competition, and THEN added a supercharger for buyers who might want that as an option. THAT would have been the home run that they needed to hit. As it stands now, I think that Mercury left the door open more than just a crack for the competition, including Evinrude with a non 4-stroke option.

I've seen ONE Verado powered boat on the water this year that I don't know for sure was not a demo or company-owned boat. It was on a 220 Dauntless in Grand Haven this spring. All of the other Verado powerplants I've seen were in showrooms or on Demo boats (for the Boston Whaler Rendezvous). To balance this report, I haven't seen ANY E-Tec powered boats on the water yet (Demo OR privately owned). I've seen many Suzuki 4-strokes and Yamaha 4 strokes, however, and I'm seeing a lot of the Johnson 4 strokes around.

Perhaps it will just take some time for these motors to trickle down to the local boating population. It's quite possible that one of these new motors may find its way onto my transom in the next year or so...but I'd like to test drive a boat powered with an E-Tec first.

One reason that Mercury went with a relatively small displacement (1.7-L) in the in-line four-cylinder version of the Verado was to avoid having to use balancing shafts to smooth out the inherent vibration in that design. The larger displacement in-line four cylinder engines need to use balancing shafts to counter vibration. The new Suzuki 150- and 175-HP in-line four cylinder engines are a good example. They have 2.7-Liter displacement and twin balancing shafts. (The in-line six cylinder is inherently balanced and does not need balancing shafts.)

Also, these Verado engines need to wind up to 6,400 revolutions per minute of the crankshaft to get to their top boat speeds, and at those kinds of reciprocating motion speeds--1,000 revolutions per minute faster than most other outboard engines--any vibration is going to be a problem.

As for these continued rumors about more horsepower from the Verado, I have grown tired of the wait. This talk has been circulating for years--literally for over two years!--and still nothing has come of it. As I said six months ago, if Mercury has more horsepower for the Verado, let's see it, please; we are all weary of just hearing about it.

The observation that the Digital Throttle and Shift is a big selling point is very cogent. The problem is that this sort of technology is adaptable to any engine, and I believe that the new Honda and Yamaha motors will be offering it, at least the throttle control part.

The power steering is interesting, but OMC was offering power steering (which ran off engine power, not electrical power) years ago. I can see where a boat rigged with twin 250-HP motors (or triple motors) could be a bear to steer, but for the average Boston Whaler owner, power-assist steering is not a deal maker or a deal breaker.

In all the tests that I have read, the naturally aspirated four-stroke motors tend to be the fuel economy leaders, better than the Verado and the E-TEC. If fuel economy is your benchmark, look for a Honda, a Yamaha, or a Suzuki four-stroke.

Jim - Mercury doesn't need more HP out of the Verado yet. The 275 is already the highest TRUE HP recreational outboard on the market, and if SE FLorida is any indication, they are big sellers. Most of the Verados I am seeing down there are the 275 size. If someone else comes out with a higher HP 4-stroke, I'm sure the Verado wil be there. Initially, the Verado was supposed to introduce at 300HP, but they felt there was no need for it currently.

Supposedly there is a 340 HP racing division version in the works, but they're still getting the bugs out of it. I can't think of any recreational engine where the racing versions don't put out more HP.

There are also some hotter performance Optimax's being developed, I understand.

Everyone seems to be ignoring Peter Morgan's post where he indicates the Verado has the BEST fuel economy where most people use their engines. It seems the only shot people can take at the Verado is full throttle economy, if anybody cares about that, and 50# of weight over the other 4-strokes. Talk about marketing hype, who really cares except the Evinrude lobby?

Why is everyone so threatened by the Verado that they have to blast it constantly? It's the best outboard on the market today, period. Nothing else has technology that even comes close. Why don't we give Boston Whaler a chance to sell a few Whalers with Verado power and see how they are received. So far, Verado owners here seem happier than the E-tec owners here, with fewer problems.

I can't think of any Verado fans picking apart the intimate details of the Evinrudes, like the Evinrude people are doing to the Verado. Talk about "looting". No engine is a perfect solution, and one just has to decide for themselves which features mean the most for their application.

A real credit to the Japanese engine fans here is that they are staying out of this Verado trashing.

LHG, I think people trash the Verado because you say things like the Verado "is the best outboard on the market today, period. Some people may not feel the same way as you.

I am brand loyal to Honda and think they make a fantasatic product but I am not going to say that Honda makes the best outboard on the market today. It will only provoke others to say that it is inferior to the brand they are loyal to.

All of the new generation outboards have similar performance and fuel economy (except the Verado at wot). The ETEC, Verado, Yamaha, Suzuki and Honda all make fine motors and we should acknowlege that fact instead of claiming one is better than the other.

I'm sorry Larry but I could not find one post from an actual owner of a Verado on this forum. Please point them out to me!!
Has someone given performance data from thier boat with a Verado on it here????
Other than the weight and reported fuel economy I have not trashed the Verado. Have you purchased one! I don't think so!

Amen! Perry. And Honda does make a good engine. I in fact have recently been looking at boats with Merc engines on them. Unless I'm missing something, the Boston Whaler is not meant to be a boat contending in Off Shore Racing. But it sounds like you think yours will, with the Verado on it.
You have a right to your opinion but that is all it is!! A skewed opinion!!!!!!!

I haven't heard many Verado owners at all on this site, there don't seem to be a lot of them around here. It probably has something to do with the fact that this platform is more difficult to implement in a repower scenario on a Classic Boston Whaler boat.

I have heard a lot about Yamaha, Evinrude and Suzuki repowers here. Given the volume of the reports, hearing a few nits to pick aren't all that unusual. I expect there to be some nits from Verado owners as well, however as I said before, there don't seem to be too many here. Any problems on the new boats are probably promptly handled at the dealer, given the fact that Whaler has an excellent dealer distribution network.

A casual observation after monitoring this and numerous other boating and outboard forums - While lots of people love to pile on and Merc bash, people are lambasted like they just insulted the holy grail of outboard technology when anything negative is stated about E-tec or Bombadier for that matter.

Only someone without a pulse would not understand the fact that all engines - regardless of technology - will have a problem here and there. Further, all manufacturers will produce a "lemon" from time-to-time. If you want a Verado, buy one and if you want an E-tec, good for you, buy one. Make your decision and be happy. There is no no shortage of Verado's hanging on the back of go-fast bass boats in certain parts of the country and these guys could give a hoot less that it gets "X" amount less fuel economy at WOT than an E-tec, Opti, or whatever.

Perry, I have to accept your criticism, as I agree "Best" was a poor choice of words, and too difficult to quantify.
(Even though JD Powers likes to use it)

But I do think the Verado offers the highest technology today, as my next sentence indicates, which what *I* meant by "best". This produces the quietest 4-stroke running sound, that many have confirmed, and excellent 4-stroke throttle response. The DTS controls, Smartcraft instrumentation, super smooth steering, pedestal transom mount, and supercharger are all features that nobody else yet has. Even the Revolution-4 props that these engines often run are in a class by themselves. They are so far out they look like no other 4 blade prop.

I think there are several Verado owners here already, probably posting more in the Post classic section. 320 Outrage and 305 owners come to mind, and they seem to be really getting popular on other new Whaler sales also. One of these days, I will join that select group too.

If you, reading this, were to buy a new Boston Whaler, would you get a 4-stroke or Optimax on it? Mercury is saying that by next year, 85% of you would opt for 4-stroke, either conventional EFI or supercharged EFI Verado.

bigjohn1-- I guess the salmon and off shore fisherman who actually put on far more miles than the bass boat people (sometimes 28-35 or more miles there and back even before trolling all day) also don't care about fuel economy??? I think not!!! The average Joe with big outboards doesn't care either???? That is not what I hear at the ramp! The big Charter boats have taken it on the chin lately and will from now on! They can only pass so much on to the customers.
Larry-- JD Powers actually does some real scientific polling, not a personnel opinion. They get paid big for it.When they say best they have numbers to prove it.
The new boats come with Mercs on them because Mercury owns Whaler. Not rocket science there!!
If Mercury says 85% want the 4 strokes, that sounds like thier death sentence for the Optimax.

The resident BRP lobbyist shows up once again!!!!???? Be careful when drawing comparisons between bass fishermen and salmon/off-shore guys. I am not comparing them - just stating an opinion based on my first-hand observations of the Western Ky/Western Tennesse area on the Ohio and Tennesse Rivers along with various lakes in both states. I'll grant you that off-shore guys (myself included) are very concerned about fuel efficiency. My comments stand though,

"There is no no shortage of Verado's hanging on the back of go-fast bass boats in certain parts of the country and these guys could give a hoot less that it gets "X" amount less fuel economy at WOT than an E-tec, Opti, or whatever."

Most (notice I said most and not all) Bass Boats want to go fast and beat competing boats to a prized fishing hole.
Many of the non-tournament "regular" guys want bragging rights at the ramp for having the fastest ride vice the most fuel-eeficient ride. Generally speaking, there is a
different boating "culture" on that side of the fence.
If you don't like it, get over it????!!!!!

Sorry Bigjohn, But the title of this post is fuel consumption.
If you look, I didn't say anything about the E-TEC in my last post. As far as fuel is concerned, if you put the kind of miles I do in my boat and spend the amount of time I do on the water, fuel economy would be an important factor. Which is the point of this particular discussion on fuel consumption! I will take your word that you saw a lot? of Verados in the area you describe. I haven't been down that way in a while.I've fished a bunch of lakes down that way. As far as comparison why not. Since we were talking about fuel economy I would still say the bass boaters don't put nearly as many miles in a day as we do so why would economy be a big concern. That again is the title of this post.

I just read two interesting performance reports on Verado-powered boats, and both were very strong in their praise of the fuel economy. I'll dig those up and post some figures.
LHG posted 10-05-2005 02:49 PM ET (US)     Profile for LHG    
All of the misleading comments on supposedly bad fuel economy of the Verado is coming from the Evinrude group, who think all of us run our outboards continuously at wide open throttle.

The fact is most of us don't, and where we run them, the Verado fuel economy is excellent. For that ocassional burst of speed, to blow away the local Yamaha F225 or E-tec, who cares about the 1/2 gallon of extra gas required!

Fuel economy is quite a concrete topic--it is a number. If it is high or low, it is a number and not very subjective. So it is hard to be mislead.

In POWERBOAT REPORTS (October 2005) the editors gush about the fuel economy of a DONZI 35 with a pair of 250-HP Verado outboards. The boat runs most efficiently at 4,500 RPM (nearly 40-MPH) where it gets 1.6-MPG. They compare this to several other large center consoles they tested:

DONZI 35, Verado 250's = 1.6 MPG at 40 MPH
PURSUIT 3480, Yamaha 250's = 1.3 MPG at 40 MPH
PALMETTO CUSTOM 33, Yamaha 300 HPDI's = 0.9 MPG
SEA-VEE 34, 250-HP Suzuki = 1.3 MPG
HYDRA-SPORTS VECTOR 3300, Yamaha 250's = 1.1 MPG

But the problem with this comparison is there is no basis to compare the engines as each is on a different boat.

TRAILER BOATS reports on an ANGLER 2900CC wth a pair of 250-HP Verado engines. This boat tops out at 2.2 MPG at 31 MPH. The editors do note that the rigged up Verado engines add 1,400 pounds to the transom. That is a bit much for most Boston Whalers to handle.

The best comparison was when the Verado was tested head-to-head with two other engines all on the same boat. There it was bested by the naturally aspirated and larger displacement Suzuki for best fuel economy.

As the old saying goes, there are lies, damn lies, and statistics.

The only conclusion I can draw from the PBR comparison is that the Donzi 35 is lighter than all of the other boats.

Did Trailer Boats report a top speed for the Angler?

The big 29-foot ANGLER hit 60.6-MPH with the 500-HP Verado pair. That speed dipped fuel economy to 1.2-MPG. Propellers were 23-inch-pitch MIRAGEplus three-blades.

One problem in all of these fuel consumption tests: the optimum fuel economy does not always occur at the same engine or boat speed. For example, I looked up the results of the Yamaha 250-HP four-stroke twins on the Pursuit mentioned above. They had better fuel economy--about 1.5-MPG-- at a lower boat speed, around 25-MPH.

I guess you need to decide what boat speed is the most important for you. If you think you'll be running 40-MPH all the time, compare fuel consumption at those speeds. If you think you'll cruise at 25-MPH, compare fuel consumption there.

Also, the propeller choice can really influence fuel economy. With the right propeller, and engine can look more fuel efficient.

LHG posted 10-06-2005 01:36 PM ET (US)     Profile for LHG    
As interesting as all of this fuel data is from the boating "rags" and boat/engine manufacturers, I think, in the end, the fuel economy of any 3 star engine, 2 or 4 stroke, is so close that this makes fuel economy almost impossible to judge as an overriding purchasing factor.

After just plain old brand loyalty, I think ease of operation, and quiet running at cruising speed and the MOST important factors, since that is what you live with hour after hour. Next would come reliability (something that can really wreck your boating enjoyment) and convenience of service access. Then performance and engine appearance, and finally this close match in fuel economy at the speeds you normaly operate.

In addition, all of this pretty much only applies to the used boat, re-power market, since almost all name brand boats no longer offer much choice in power. With Whalers, it's now either an Optimax 2-stroke or a 4-stroke, all in black

Fuel economy does vary quite a bit between motors is tested using the ICOMIA duty cycle which all manuafacturers comply with. The boating magazines should also list the ICOMIA fuel consumption averages along with their mpg and/or gph results at different speeds. That way everyone is on a level playing field, no matter which engine is being compared.

The ICOMIA duty cyle is the same series of times at different power outputs, I don't have exact figures handy, but it is the same duty cycle used in the emissions testing for all outboards.

There was raw data of a Swedish magazine’s 250 shootout posted on The Hull Truth last month:

Boat: Anytec 750 SP aluminium boat, 7.50 m x 2.26 m, weight 950 kg without outboard, weight with outboard and 4 persons onboard approx 1600 kg. Motors: E-TEC 250, Verado 250, Suzuki 250 and Yamaha 250.

I’ve taken this data and produced comparative graphs of mpg versus boat speed (i.e. in the same format as I have previously posted on this forum). Unfortunately, the figures were taken at 500rpm increments from maximum rpm down to 3500rpm or so. What is really interesting is that as we all know by now, the Verado was a gas-hog at WOT, but at the sort of cruising speed that most of us feel comfortable with in the open ocean, i.e. around 25 to 30 mph, the Verado looks like being tops. Trouble is, the data doesn’t go down to low enough rpm for the curves to peak and decline.
Anyone interested in seeing the graphs is welcome to email me at tlco@xtra.co.nz and I’ll email my pdf file.

LHG- Larry-- The title of this topic is fuel economy. ATF asked for the real data which Mercury does not offer. Not brand loyalty, weather you wear black, and not your personnel opinion on which is more powerful. Why can't you offer more than your personnel opinion. The real data that is available from independent sources suggests that the Verado has significantly poorer fuel economy than the others. I know the price of gas doesn't mean anything to you!

Peter, that is very informative data you provide. I really like the fact that the test you refer to used identically loaded boats for true head-to-head comparisons. Can you recall the name of the actual magazine which ran the test?
I watch closely both the Verado and E-tec technologies as they both seem to be cutting edge and the wave of the future. I think that for the prospective new boater buyer
with his heart set on Merc, nothing in that report is going to stop him and the same can be said for one with his heart set on an E-tec. I can think of more than a few situations where - assuming your data is valid - a person may well choose Verado over E-tec, the off-shore commercial charter business being one. For a guy making a living off daily charters, and with today's gas prices, a few more mpg is a big deal. As you correctly infer, the overwhelming majority of outboard-powered off-shore boats rarely see WOT speeds.

PJM was kind enough to send me his PDF file per my request. I've taken a look at it and have spotted a problem that makes it difficult to conclude that any of the 4 engines tested is the most economical at cruise or at any other speeds. PJM has also spotted the problem.

The problem I find with the test is that its hard to judge the motor's actual peformance because the results are masked by the use of different propellers on each motor. While the magazines like to do their testing with propellers from the manufacturer, the problem is that there are significant differences in performance from propeller to propeller. Some are designed to run well at high speeds while others are configured for cruising or general all around performance. This should be easy to understand simply by looking at Jim's propeller test report, see continuouswave.com/ubb/Forum4/HTML/001019.html .

In the case of the E-TEC, it uses a 14 1/2D x 24P Raker, a highly raked propeller typically used on light weight bass boats. In the case of the Verado, it is equipped with a 14 3/4D x 21P Mirage Plus, a propeller you might expect to find on a cruising boat such as a Whaler, but not on a bass boat. The Suzuki was equipped with a 16D x 24.5P and the Yamaha had a 14 1/2D x 23P Pro Series propeller. I'm not very familiar with the propellers used by the Suzuki and the Yamaha but the Yamaha Pro Series propeller is said to be a bass boat propeller meant for running the motor high on the transom and at high trim. Interestingly, the Yamaha appears to be mounted the lowest of all of the motors according to the report from PJM but yet achieved the highest top speed.

The Verado 250 was the slowest motor with the highest fuel consumption (26.9 GPH v. 22.3 GPH for the lowest) at WOT of the bunch tested and I have to wonder whether the Mirage hampered its top end when put up against bass boat propellers. To use a near equivalent propeller to the Raker or Yamaha Prop Series, the testers should have used a Mercury Tempest Plus I believe but that probably would have probably reduced its cruising economy.

The long and short of it all is that its difficult to conclude with any accuracy which of the motors would be most economical to run with an optimized propeller which I tend to think would be the same propeller for all motors.

First, a thank you to Peter for the pointer to that old thread. I enjoyed reading it, and found the most interesting content to be the fellow who mentioned that he bought gasoline at $1.05/gallon in August of 2002. My oh my, how things have changed. Gasoline at $4/gallon--the price it was selling for at a small marina last weekend up north--makes everyone much more interested in fuel consumption figures.

The influence of the propeller on fuel consumption is a major factor. In the test data mentioned by PJM, the Verado has the best fuel economy around 30-MPH. I think this is due to the MIRAGEplus propeller being used.

Unfortunately, because these four 250-HP engines have different ratios in their gearcases, you cannot test them all with the same propeller. But you could, as Peter suggests, at least test them all with propellers of similar characteristics. If this were done, the influence of the propeller design would not be as great on the outcome of the fuel economy figures.

Actually I thought I had put a link to your propeller test continuouswave.com/whaler/reference/propellerWDSingle.html but apparently the copy and paste function did not take and used the last link I had copied and inserted in another thread yesterday. Nonetheless, it does show how things have changed quickly.

Larry, I do agree that on this particular test its difficult to draw great conclusions on the winner given that they were all running different propellers and different heights on the motors. However, if you look at the Whaler test reports where they run both the Optimax and the Verado with the SAME propeller, the Verado almost always seems to come up a bit short relative to the Optimax. Again, those numbers do require some interpretation because Whaler seem to have a knack for running the Verado powered boats light on fuel, in some cases quite light.

Interesting discussion going on here. It is my experience that there can be more variation in fuel economy for any given motor at any given boatspeed, using different propellers, than there is between different brands of motor using each brand's propeller. An interesting point that Peter raised in an email to me is that no shootout he'd ever seen used the same family of prop, albeit of differing pitches to allow for differing gear ratios and recommended rpm bands. He suggested that all shootouts should use the same family of prop, and run the motors' gearcase centrelines the same distance below identical hulls, and only then would we be able to make a valid comparison of fuel economy and engine performance generally. Of course, each manufacturer dyno-tests its engines -- wouldn't it be great if only they would let us have the torque, power and specific fuel consumption curves! Volvo publishes them for its diesel sterndrives.
If you really want good fuel economy in a 20ft - 24ft trailerboat, consider the all-aluminum Volvo D3 common rail diesel sterndrive, which has a dry weight of only 750lbs including heat exchanger for both block and exhaust manifold, but excluding the prop. It has a cast stainless steel exhaust elbow to eliminate the need to regularly replace the most corrosion-prone part on inboards. Power output is 181hp at the prop. Dyno test results are published on Volvo's website.

In the northern half of the U.S. diesel pricing tends to be seasonal, and rises in the fall and winter. I just noticed the following prices:

UNLEADED GASOLINE = $2.71-gallon
DIESEL = $3.14

At this sort of pricing differential (15-percent premium for diesel), the fuel economy on a diesel engine has to be rather much better than a gasoline engine to make up the added costs.

Jim H,

The prices you posted are for on-road diesel (road taxes paid). Off road diesel can be run legally in boats. Currently I'm paying 2.54 a gallon for the winter blend (on-road is 3.16 here).

Diesel competes with home heating oil in the wintertime (in terms of refinery capacity), and therefore is more expensive in the winter months when all those homes in New England, the worlds largest home heating oil market, are running their furnaces to fend off the cold grip of Winter.

Even so, I don't think it is the price of fuel keeping those diesel powered boat off Lake Michigain during the winter.

During prime boating season up north, the balance leans the other way and is well in favor of the diesel, especially considering the added efficiency over gas. Now that a 600 lb outboard motor with supercharging and inter cooling has become acceptable to the market, maybe a diesel outboard is in our future. BillS

It didn't always used to be that way. Only a couple of years ago diesel fuel used to be priced below unleaded gas around here. Within the last year or so it has been priced above premium gas. I think there are regulatory reasons for this price swing, and those regulatory reasons relate to the need to make diesel fuel from the more expensive low sulfur (sweet) crude than higher sulfur fuel.

Relative pricing for gas and diesel is all messed up right now because of the refinery outages post KatRita.

Normally, in the summer when we use our boats most, diesel is less expensive than gasoline, as the refinery runs needed to produce enough gas to meet summer demand prooduces an excess of distillate (what diesel, heating oil, kerosene and jet fuel all are).

Hello All,
Thanks for your help. I think that I am going to go with Verado. They are all great engines, but I really like the performance of the engine. I also like how quiet it is, with the new control system. I will let you all know what type of fuel economy I get with it.
Thanks again,

Re: Diesel vs Gasoline prices

Plotman has it right--I think all the refineries in North America are optimized to produce gasoline, and production of diesel, kerosene, and home heating oil are all by-products. Because demand for gasoline is not very seasonal, they are cranking out gasoline all the time. The amount of diesel, keresene, and home heating oil is therefore about the same no matter what time of year. When demand rises in the winter, there is no extra supply available, because these products are by-products. In summer, there is not much demand, so lower prices.

Roger on that influence of ice on boating in Lake Michigan in the winter.

RE: gas vs. diesel prices

David is 100% correct. Another factor is that the diesel sold in the winter (at least up here) is a different blend than that sold in the summer. My understanding is that this blend is fundamentally more expensive to produce as it uses more expensive #1 fuel oil plus additional additives...

-WS

p.s. this is the biggest difference (in both amount and percentage of difference) I have ever seen between gas and diesel...2.31 vs. 3.25...ughhh!!

In the refining process, Getting diesel out of crude is amongst the first distillation processes, it is common to both fuels. Getting gasoline requires additional processing and catalytic cracking to get the long chain molecules put together that make up gas, and the synthetic base for other petro products. The factions of crude that make up gas and diesel go through the same initial processing. Diesel and heating oil come out of the process sooner, then the base goes on for additional processing to make gas. Diesel availability (and price) is driven in large part by competing for limited distillation capacity that is also uses the same base factions of the crude for home heating oil. Hence, the seasonal fall-winter bump up in diesel price as the refineries start producing and stockpiling heating oil for the winters. Diesel and Fuel oil don't compete with gasoline production, once the fuel oils come out of the faction, the remaining base and higher factions go on to cracking to make gasoline. At least, that's the way my mom explained it all to me about 25 yrs ago when she ran one of the Standard Oil test labs. BillS

Outboard motor brand loyalty for me consists of finding a decent, reliable motor of any make with a good track record--for a new model at least a couple of year's successful use by commercial fishermen, charter boat operators, rental boat companies--reasonable fuel economy, local access to a good certified mechanic, and a stand-up warranty. But then again I guess I'm just an old conservative stick-in-the-mud, more concerned with stuff like that than the truly important things like:

"When you see a Verado powered boat, everybody comes around and looks, and with their premium pricing, everybody knows this is a guy who can afford the best."

Oh my God...now I understand why everybody hasn't been coming around and looking at my Yamaha four stroke and muttering to themselves, 'Hmmmm, wow, this is a guy who can afford the best.'

Man oh man oh man...there's really a different world out there... ;-)

Anecdotal information from a recent visit to a large, reputable Boston Whaler dealership that sells all major brands of outboards:

A majority of the larger new Boston Whalers in the yard had Verados on the transom. There was also a Verado on the back of a new 180 Dauntless.

When discussing repower options for my 1989 Outrage 22 Cuddy, the unanimous consensus among the shop's staff and ownership was for a 200 or 225 E-TEC.

Regarding fuel economy, just about anything that's legal in the state of California is going to get superior milage to the conventional 2-stroke that it will be replacing. From the data I've seen, the fuel economy numbers among the competetors is close enough to call it a push, and I'm evaluating my choices on other more pertinent criteria such as weight, size, and reliability.

I hear Merc is working on even smaller, non-supercharged Verado models. It will be interesting to see where Merc goes with Optimax after spending all this time and money on Verado.
Being a Mercury specialist technician since 1979 I'm really excited to see how outboards are changing these days. I am a big fan of the new 3 cylinder Optimax engines...but I fear Verado may spell the end. And I guess that's ok if they turn out to be dependable. I don't care how "whiz-bang" a new engine is...if it's not dependable it is worthless.
As an independent shop owner my real fear is that I may be "locked out" from working on the newest motors...I hear that the latest Merc computer diagnostic system will need to be periodically updated...and this can only be done through the exclusive dealer MIDAS connection. That's a shame. I'm really not ready to retire yet. Guess I maybe limited to specializing on just the OLD stuff....like Optimax!!

There is some good information about the future of the OptiMax engine contained in:

http://continuouswave.com/ubb/Forum1/HTML/010613.html

There are some who believe that production of the OptiMax will be reduced, and the OptiMax will become a specialty or high-performance model in the Mercury line. The standard engine line up will be all four-stroke. It will be particularly interesting to see what happens in the 75, 90, and 115-HP range. The OptiMax engine has never been a great fit to that horsepower range, and all the current four-stroke engines are adaptations of power heads purchased from Yamaha, an arrangement which will end in 2006.
