[Give] your opinions on [using twin four-cycle motors to re-power a Boston Whaler OUTRAGE 22]. California waterways dictates CARB-THREE STAR compliance. I would like just input on twin four-cycle motors. The [Boston Whaler OUTRAGE 22] will be used for fishing and skiing on fresh water lakes and fishing and diving offshore islands here in Southern California.

Regards,

Dave

How much HP do you want on the transom?

Twin 130's.

Go with a dealership that is local and whom you trust. Buy their brand and live happily ever after.

Everything else is just opinions.

Since I know you will get them, I'll start.

Screw the blah blah....

Get twin E-TEC 130's and don't pay the weight and performance penalties for the 4 cycle engines. You can brag to the Greenies in Cali that your motor's technology won the EPA Award for clean air excellence - no other outboard maker can claim that.

The motors will exceed CARB 3-star compliance and deliver performance and quiet, virtually smoke-free operation. They will troll all day without complaint, and instantly give you the kick needed to get home and power through the afternoon slop.

Peter: Minimum horsepower to pull waterskier's. Will 90's get that done?

Side note: Dealer network around here is very good for all brands of outboards.

Most of the 4-strokes that would best suit your needs are going to be just shy or just over 400 lbs and will range from 75 HP to 115 HP. Your Outrage is rated to 240 HP (unless it is a Whaler-Drive model, and then you have more options), so 115 will define the upper end of HP. One thing I would encourage you to consider is counter-rotating engines and this feature is often not available on lower HP motors in this class. Most 115 HP models of any manufacturer will offer this. Since weight between the 75-115 HP motors is comparable, I'd opt for some counter-rotating 115 HP motors (pick your manufacturer-Yamaha, Mercury, Suzuki) if it has to be 4-stroke. The Honda 115 is a good engine, but it is a pig at more than 500 LBS

I believe the lightest weight 4-stroke 115 is the Mercury Verado block EFI. I think the lightest weight 90 4-stroke is a Honda or Suzuki, but they may be a little light on top end speed if that is what you're after. I would want twin 115's.

115 Optimax's might very well be worth a look, at 370#. SOS here says they are a great engine.

Since we are talking about any engine, I would not recommend the Yamaha F115 for one reason.

The vapor separator tank (VST) is mounted inboard of the intake manifold. It is a 2-3 hour job to service. Since it should be inspected/cleaned each year, it's a pain. No other Yamaha has this design.

Other than the above, it is flawless. It's weight is 402 lbs dry in case you are wondering.

I agree that twin 115's are the lowest I'd go. I hate to say that as I'm thinking of putting my 90's on a 22' hull, but really can't justify it - it is too little power.

Too bad you aren't okay with the DFI 2-strokes because E-TEC or OptiMax would be good options in the 115 HP range.

I suggest you go with the STRONGEST dealer in your area - since you have all options open, pick on quality of service and customer satisfaction.

If you intend to use the boat for water skiing, you will have a minimum of three people associated with the boat (two in and one on skis). I don't think twin 90 4-strokes are going to be up to the task. I think 2 x 115 HP is needed and all the 4-stroke 115s at 400+ lbs are too heavy. Frankly, I don't think there are any good clean and green, twin outboard motor options for Outrage 22. Even the DFI 2-strokes at 375 lbs, which would have a nice hole shot compared to the 4-strokes, are putting too much weight on the transom.

Since you are going to use the boat for diving, I think using twin four-cycle motors is a good choice. The transom will be so low that divers will be able to re-enter the boat easily.

I would have thought the max HP rating of 240 HP for 22' Outrages of this era was derived in part by the availability of 120 HP engines from both Johnson and Evinrude which would combine for 240 HP. Since the hull was designed for twins, this seems to make sense. The 120 HP JohnnyRudes of this vintage were 370+ lbs a piece, pretty close to the weight we are talking for twin 4-strokes. Was this hull really incapable of properly handling twins within its HP rating when it was designed knowing what was available at the time?

The Outrage 22 was designed in the mid 1970s with the first production year being on or around 1978 as I recall. It was the cross-flow V4s, not the loop charged V4s, that were available at the time the Outrage 22 was designed.

The OMC loop charged V4 ("V4 Looper"), which came out as 120 and 140 HP models and later consolidated to a 130 HP model, weigh 365 lbs. They were not introduced to market until 1985.

The OMC cross-flow charged V4s ranging from 85 to 140 HP (crankshaft HP) weigh anywhere from about 275 to about 305 lbs depending on how they are configured. Thus, at the time the Outrage 22 was designed, a pair of OMC V4 115s wouldn't put more than about 600 lbs on the transom.

Every Outrage 22 that I have seen equipped with a pair of V4 loopers appears to ride low in the stern.

The current specifications for the Guardian 22 show a maximum transom weight of 720 lbs. The transom on the Guardian 22 is 5 inches higher than it is on the Outrage 22. If one wants to modify the transom of their Outrage 22 to raise it 5 inches, then I think the so modified Outrage 22 could accomodate 720 lbs on the transom and provide enough freeboard between the top of the transom and the waterline. Without such a modification, I wouldn't go much over 600 lbs.

Anyway you cut it, in this day of greatly improved and super heavy outboards over the old stinky 2-strokes, a pair of 115's is going to weigh between 750-lbs to 825-lbs no matter what they are. A cut transom 22 outrage in good, dry condition can easily handle that weight as long as it doesn't have the 129 gallon fuel tank sloshing fuel to the stern.

If it were my boat, I would seriously consider installing a pair of 2-stroke Merc 90's while they are still available brand new. At 100 HP each, these would move a 22 right along very well, with good low end power and only a total weight of 610-lbs. What a bargain in price, HP and economy. The additional cost of fuel will take years and years to justify the higher cost and additional weight of the clean engines.

Larry -- Apparently you didn't catch the original poster's location ==> CALIFORNIA. As of 2008, Mercury withdrew low budget brand new 2-stroke outboard motors from the market in CALIFORNIA.

I'd jump on Dave's suggestion-Twin 130 E-tecs, or twin 115 H.O.'s, provided they are available in counter-rotating models. All the favorable attributes of 4-strokes and the best power-to-weight ratio of the bunch. Your skiers will appreciate the holeshot.

Is the desire for twins due to the fact you might want an emergency way to get home should one engine break down in the southern California ocean? If that is the reason, would you consider one large 4 stroke 250 (pick your brand... I owned a Yamaha F250 that was flawless, as well as two F150's)), and a kicker to serve in the emergency role?
L H G posted 05-27-2009 08:39 PM ET (US)     Profile for L H G    
Peter, if it were my boat, it wouldn't be in California!

First, California is putting itself and it's own citizens in financial trouble, and now the rest of Nation is rushing to follow in their environomental footsteps so we all can be there too! It's really too bad they can't still buy a 2-stroke, and save a few bucks here and there. The 2-stroke outboard was never as bad as they made it out to be, and still isn't.

You don't need Cr engines in 115hp range if you have hydraulic steering. My bud has twin 115 Suzukis and steering is fine. Suzuki does offer 115's in CR fashion now though. Janis has a 22 with twin 115 Yamahas which weigh close to 370 each and boat rides and sits fine. I would probbaly stay away from Suzuki though at 416 each and lean towards the other brands. Place by me has new 115 E-tec leftovers for $7k each. Personally I would put a single 225 or 250 Suzuki on it and get SeaTow.

You don't ever "need" counter-rotating engines; it's just very nice to have them, especially if they are available. The maneuverability issue alone is worth seeking them out. I had a Grady White with twin, non counter-rotating 175's. That thing was no more maneuverable than a single, and when the wind is whipping in tight quarters and you have bimini top up, you'll appreciate the CR engines. You can mitigate some of the down side of not having them-like hydraulic steering and adding trim tabs to even out any torque lean the boat may experience, but for me, once I got a hold of CR twins, there's no going back. I am thankful I have this feature every time I go out.

My 1990 [22-footer with standard notched transom] was powered with twin Yamaha F100's. It ran great. With full 77 gallon fuell tank and minimal gear, [top speed was] 35- to 38-MPH. I only ran stock, three-blade aluminium propellers, 17-pitch. It was actually pretty quick out of the hole and I could easily yank up a slalom skier. Very quiet and fuel efficient. On the down side, it was stern heavy. Sitting static at my dock, the transom well would not drain and the two rear plugs had to be in so 1- to 2-inches of water would not sit in the rear compartments. I sold the engines with the idea of one large single. I narrowed it down to Yamaha F225 or F250 with a small kicker, 250 Verado, twin Yamaha 115's (counter rotated and heavier than the F100's), or Mercury 250 Optimax XS. This was two years ago, and the boat has been "naked" since then. It gets down to the costs and economy of scale. Although I am a big Mercury fan, the resale in Hawaii for Mercury transoms is terrible! Yamaha rules. The new F250 with variable timing is my first choice, but again, costs rule. I am looking at a pair of F90's, used, for a good price. I realize I will be full circle back to my F100's, however, there will be a 250 four-cycle on her transom, hopefully, in the near future.

BTW, I once had 14 people in the boat--I know, overloaded--and it came on plane with little effort and still ran WOT about 25-MPH! With twins, I need 20-inch shaft engines. Yamaha only offers the F115's in a counter rotation on a 25-inch shaft engine. I was going to create a 20-inch shaft left hand lower unit by changing the drive shaft on a new counter rotated drive.

Last thought, with the F100's, I could not plane on one engine. Perhaps with different propellerss, I would have been ok. Thanks and GoodLuck

I had a few moments at the helm of a Boston Whaler REVENGE 22 powered with twin four-cycle HONDA 90-HP motors. I think they were model BF90, not to be confused with the new lighter and more advanced HONDA BF90D models.

I do not recall any particular problems with the weight of the twin four-cycle motors on the transom, although with a REVENGE model the extra weight of the cabin superstructure on the forward portion of the boat tends to help offset any extra weight on the transom.

The twin HONDA BF90 motors ran very smoothly. They gave me a feel as though they were electric motors from their smooth and gradual power up, their quiet operation, and their somewhat slower throttle response. The boat ran nicely. It was not a speed demon or extremely quick to accelerate. The fuel efficiency was enviable when compared to my older carburetor two-cycle motor.

Be sure to consider this when selecting twin engines. If you can not plane on just one of the pair (with the motors propped for normal, twin engine use), you are better off with a big single and a small kicker. For this reason, I think DFI 2-strokes such as E-TEC and Optimax are a better choice for twins on an Outrage 22. I believe the low-end power of a 115-130 hp 2-stroke will get that Outrage 22 on plane with a single motor. At 390 pounds each, the E-TEC 130's are really at the limit of how much weight I would consider on a notched transom 22, and then would absolutely relocate batteries to the console, install big bilge pumps in the rear sumps and plan to run with the aft sump plugs closed all the time. My sense is that on a standard Outrage 22, transom freeboard would be on the low side. At 431 pounds, the Optimax 135 is in my opinion too heavy. The Optimax 115 at 375 pounds is a bit lighter than the E-TEC 115/130, but is only a 1.5L 3 cylinder compared to Evinrude's 1.7L V4. Either way, I think the transom can handle the weight, so long as you are willing to live with lower freeboard and plugged sumps. Note that outragesteve reports a stern-heavy condition with Yamaha F-100's, which are listed at 356 pounds per motor. It's my understanding that this motor has been reconfigured at the F-90, now listed at 369 pounds.

I repowered my Outrage 22 Cuddy (in California) a few years ago, and went through a similar analysis. My conclusion at the time was that there was no CARB 3-star outboard available that would give me the performance I wanted in twin engine configuration without a weight penalty that I felt was unacceptable. I am very happy with my choice of a 2.6L E-TEC 200 and my old 15 hp Mercury kicker. If you go with a big single, there are a lot of choices in both 2-stroke DFI and 4-stroke outboards.

Chap--Thank you for posting the link to the images showing the static trim of a Boston Whaler OUTRAGE 22 with notched transom equipped with twin two-cycle engines from OMC. Your pictures show the load on the transom and the freeboard that remains. I am certain others will find them informative. And, by God, those are some big galooping monster engines--ain't no four-cycle gonna dwarf those monsters, BABY!

Mr C,

A friend of mine had a 22' outrage, mid 80's model. He put twin 115 Suzuki 4 strokes on her and after using her a few times pulled the engines and built up the transom 5 inches as stated in a post above.

With the standard transom the boat just sat to low in the water and would take to much water over the transom. He operated the boat in a fairly rough environment. In calm waters it might have been O.K. Also the boat was hard to get on plane unless he punched it from the beginning. He had to move a lot of gear forward to be able to plane at lower RPM'S. It would also drop off plane very quickly as RPM"S were reduced. It may have been different had it been a WD model, I'm not sure of the weight capacity of a WD model.

My 1986 22' guardian with a 1999 225hp Optimax and a 18hp 4 stroke Tohatsu kicker planes very easy, and starts to get on a plane at about 12knts. I agree with other posts above that keeping the weight down is your best option, depending on what you plan to use the boat for. Just my thoughts on this.

Aloha Sean

I was intent on putting twins on my 1989 22-foot [invented a new acronym for a Boston Whaler boat model which I think might mean "OUTRAGE"]. I cross the Gulfstream to the Bahamas alone. I kept running into knowledgeable people who were telling me no. Double maintenance, double trouble. I ended up with a 225 Yamaha 2cycle fuel injected and a 15hp 4cycle kicker. Best choice I ever made. Less fuel, less crowd on the stern, half the cost. Get youself a good Yahama225 and BoatUS towing coverage(which you will probably never use). Put the savings into Bennet trim tabs.

Thanks for the suggestion that re-power of a Boston Whaler OUTRAGE 22 with twin engines may be more expensive, more troublesome, and require more maintenance than installing a single main engine with a small auxiliary engine.

Let's examine this on the basis of purchase cost. We will use Yamaha four-cycle engines and base their price on the advertised price from a major seller, Ed's Marine Superstore.

TWIN ENGINE RIG

2 x Yamaha F115 = 2 x $7,300
TOTAL = $14,600

MAIN and AUXILIARY RIG

Yamaha F225 = $13,500
Yamaha 8-HP High-Thrust Electric Tilt = $2,300
TOTAL = $15,800

I do not see much variation in rigging costs. In each case we have two motors. We will need two sets of rigging: controls, harnesses, gauges, alarms, batteries, and so on. I would judge the rigging costs to be equal.

The initial purchase and installation costs then appears to favor the twin engine rigging by about $1,200. This contradicts the premise that using a main and auxiliary set up will be less expensive.

In terms of trouble or repairs, in each case we have two engines. One could say that with a main and auxiliary rig the majority of the time only one engine will be running. If the boat is in operation for 100 hours, in the case of a main and auxiliary their total combined running time would not be much greater than 100-hours. We have seen that it is common for typical boat operation to be at low speed almost half the time. We could speculate that the usage ratio might be 40:60 in favor of the main engine. Thus after 100 hours we would have 40 hours of run time on the auxiliary and 60 hours on the main, a total of 100 hours of engine run time

With twin engines it will be common for both engine to run during the high speed operation of the boat. During low speed operation it will only be necessary to run one engine. Each engine will have 60-hours of high speed run and 20-hours of low speed run, or a total of 80-hours. The total engine run time in 100 hours of boat operation will then be 160-hours.

On the basis of the comparison above, it is reasonable to conclude that the main and auxiliary rig may be less troublesome as its engines will have less running time on them as compared to a twin engine rig.

With regard to maintenance, the seasonal nature of most boating and the low total run time each season tend to reduce any advantage of the main and auxiliary rig over the twin engine rig. Seasonal and annual maintenance will be the same for each. Thus no particular advantage for either.

In total, the comparison of twin engine rigging compared to main and auxiliary engine rigging has mixed results on the three points of comparison: cost, trouble, and maintenance. Lower cost favors twins. Less trouble favors main and auxiliary. Maintenance is equal.

In addition to jim's analysis above, I would introduce "intangibles" as they tend to be primary reasons for choosing twin engine applications. These would include enhanced maneuvering (especially in tight docking situations) and superior single engine performance in the event of an engine failure at sea. If you want to bring fuel consumption into the equation, a specific duty cycle would need to be identified, but the likely differences would be negligible for most.

[After a dormant period of about nine months, this discussion has been revived with the following information added:]

[The] boat is a 1986 [Boston Whaler OUTRAGE 22] Cuddy with the 129-gallon gas tank. Popular opinion seems to suggest twin 90-HP [four-cycle engine] as too heavy, if not underpowered. How far away are the E-TEC 90 [High Output engines or H.O.]?

Neighbor had twin 90 Yamahas and loved them on his 22. Janis has twin 115's and it flies. Twin 130's will scream. The new Suzuki 90 is almost as light as the E-Tec 90. The e-tec 90 will preform about the same as the old Yamaha 2 stroke 90's which is just OK for a 90. Not sure about the new Suzukis as they are new. There is no talk of a 90HO e-tec that I am aware of.

An E-TEC 90 H.O. is not known to me. Try E-TEC 115-HP V4 engines as an alternative.

If you step up to 115's, most manufacturers offer counter-rotating engines.
