Will be re-powering my 1985 Montauk soon and can't decide what motor to use. I have read through the posts here and have learned a lot about weight and horsepower issues. My question to the group is: If money is no object, would you re-power with a Honda 90 or a lighter 2 stroke such as a Yamaha 90? Thanks.

If money is no object then what about the other variables like,

Hole shot (will you be using it primarily as a ski boat?)
Weight (how the boat sits in the water)
Ease of service (how easy will it be to find small-town mechanics to repair it)

If those factors are very important then go with the 2-stroke. On the other hand, go with the 4-stroke if you value

Reliability (starting at the first turn of the key)
Quiet (you will barely hear it running at idle speed)
No smoke (and no oil to add to reservoir or fuel)
Fuel economy (assuming you are not running at WOT, you can get a lot more mileage out of a tank of gas with a 4-stroke).

With the above criteria, my vote would go to a 90hp E-TEC.
Hole shot, weight, ease of service, quiet, no smoke, fuel economy, it has it all.
Reliability is the only question, because they havn't got a track record yet.
However, my opinion is that the simplicity of the E-TEC should deliver the reliability.
If I was repowering a Montauk, that would be my #1 choice.

It might be worthwhile considering just what speeds and loads you use. While you can juggle around the various 90hp, they are easily beaten in economy by a smaller engine. Everything down to a 50 or 60 is usable depending on what you are doing.

Also, if a aux engine is also in your future, now is when to consider that. Even if it will be a while. Particularily consider weight. If you use up your weight allowance with the main engine then a aux may be out of the question or you will be limited to only very small ones.

If you have any areas you boat that might become four stroke only you need to consider that too.

I've a 85 Montauk powered by a F50 Yamaha four stroke. I'm adding a T9.9 Yamaha four stroke aux. For my uses that's probably close to ideal. The combo will get me into horsepower limited lakes, for instance.

I would go with a Johnson 90hp 2 stroke. Oh, by the way, that is exactly what I did. I have had the motor 2 years now and it is great. It's a rock solid engine with a proven history and for the Montauk, it has PLENTY of power. When I bought my motor, the E-TEC wasn't available. If I had it all to do over again, I would have a hard time chosing between the E-TEC 90 and the Johnson 90.

Thanks for the replies. I'm leaning toward the Honda 90 but am worried about how the boat will handle with 373 lbs. on the transom? Thanks again.

Big Wally, you're not giving us enough information. Do you plan on mounting the engine on a jackplate with setback? Will you ever have an aux. engine? Is your battery located in the stern? How much fuel will you carry? How will you use the boat? How much other weight will you carry? Do you ever plan on letting the boat sit in the water with the plug out?

The boat will not be as quick and responsive as it would be with a smaller, lighter engine. But it will still be unsinkable and it will have plenty of power when you need it.

Isn't one of the Cetacea pages devoted to an Alaskan Montauk with a Honda 90?

I'll be using the boat for harbor cruising and inshore fishing around Huntington Beach and Long Beach, CA. I wont be mounting an auxillary engine but I do have a small bait well (1/2 scoop - 20 gallons?) that I use occasionaly which is located near the transom. I have two batteries located inside the console

A quiet and smokeless four stroke sounds great for harbor cruising but I don't want the trim of the boat to look funny or the boat to handle weird with all the weight.

I feel that a Honda 90 would be a very quiet and reliable motor with plenty of power. I'm just worried about how the boat will handle/look.
Thanks

David Jenkins posted 12-18-2004 01:43 PM ET (US)     Profile for David Jenkins  Send Email to David Jenkins     
It is going to sit back heavy with the bait well, BigWally. Will you be using setback plate as well? What engine do you have on it right now? Why don't you add dead weight to what you have right now (to get it up to the Honda's weight) and add water to the bait well and fuel to the tank and see how she sits like that. If you are happy with the way it sits at the dock, I bet that you will be satisfied with the way it handles underway.
BigWally posted 12-18-2004 02:21 PM ET (US)     Profile for BigWally  Send Email to BigWally     
That sounds like a good idea about adding weight to the back to see how it will sit. Anyone know what a johnson 88 SPL weighs? Not sure what year the motor is. It's probably the original (1985). I'm not sure if I'll be using a setback plate yet. Thanks again for all the information.

Big Wally =

Legobusier has an 1986 ish Montauk with a recent year Honda 90 4 stroke. Search for threads.

The boat sits a bit lower due to weight but it is not a problem.

His website is

http://www.covingtonhendrix.com/Montauk_II/

There are more photos at that address but change the "montauk II to a single I.

IMO - Go Honda if you can afford it, or 2nd choice is Yamaha.

There you go, Big Wally. A picture tells 1000 words. WIth no setback plate and with the battery (batteries?) moved under the console, it looks fine. You might want to have legobusier send you another photo of the boat with him standing in the stern. Then you will know how it will sit with 20 gallons of water in your live bait well. See if he can have the picture taken from the stern so you can see the drain holes in the splashwell. Are they under water? How far? And you might confirm that he is using a stainless prop so that weight will be the same as yours. And finally, you might want to ask him how high he has the engine mounted. Looks like 3 holes up from the photos.

Looks like you got your mind made up but for what it's worth I have a 200hp E-TEC and my dealer sells both Honda and Evinrude. My 200hp E-TEC is quieter than my neighbors 90hp Honda. The 90hp E-TEC is quieter,cleaner and accelerates faster than both the Yamaha and Honda. It is also 55lbs lighter. No maintenance for three years.(3yr warrenty) I'm happy and my dealer says no problems in 2 yrs so far. Oh' did I mention the better mpg you will get at lower rpms. Good Luck!

The MONTAUK classic 17 is rated for 410-lbs. on the transom.

See:

Fourdfish, are your splashwell drain holes under water? Is you battery in the console? Do you use a setback plate?

If the variables are the same and one engine would allow BigWally to keep the plugs out of the splashwell drains and the other engine would require him to plus ghe drains, then it seems to me that this would be a significant reason to test drive an E-TEC.

Easy, real easy .... Honda 90!

In 1996 Whaler even rigged a Montauk with this same combination. The review was in Saltwater Sportsman Mag.

I don't believe the classic Montauk was ever rated for transom weight. I asked someone who bought one of the last and it didn't have a max motor weight plate. What probably happened was that a web developer got the 410 lb spec for the much larger and heavier 170 Montauk, and put it on the website too early.

It definitely appears the Honda 90 is a bit too much weight in this photo:

http://www.covingtonhendrix.com/Montauk/images/Mvc-132s.jpg

Look closely at how much of the bow and the original bottom paint is raised out of the water.

This is just my humble opionion, but I wouldn't put anything heavier than an E-Tec 90HP on the classic Montauk, especially one with a bait well at the transom. YMMV.

Moe--That is a good point regarding the specified weight limit on the transom of a MONTAUK 17 being tied to a web page. I wonder if there is a printed brochure with that weight listed? I have a few in my collection and will check to see if the 410-pound figure is also listed there.

Hi guys.. Thanks to Phil for emailing me regarding this thread. I'm home with the flu today so forgive me if this is not the most coherent response you've ever read.

As Phil pointed out, I have a '98 Honda on my '87 Montauk and personally think it's fine. The splash wells are under water by about 1/2" or so but performance and handling are great IMO. It's certainly a heavy engine, but I don't think it adversly effects the performance of the boat.

There was also a article in Powerboat Magazine (or something similar..can't remember which) that reviews this exact setup - Honda 90 on a classic Montauk. They gave it very high marks as well. I have a copy of it at the office that I can fax to anyone that would like to see it - just email me if you want it. Another forum member here sent it to me a few months back.

Hole shot is good and top speed is about 42. I do have a stainless prop as David was wondering. I can post the specs of the prop if you like.

Also, fuel tank (Pate 24) is under the RPS and battery is under the console, so that helps the weight distribution.

I would not hesitate for a second on the Honda. If I still own this boat when it's time for me to repower, I'll most likely stick with the Honda.

Feel free to contact me directly with questions if you like as I may not be monitoring this thread due to my drug induced state :)

Thanks,
Chris

I have the E-TEC 90, with a 4.5-inch set back bracket, and the battery in the stern. The splashwell is dry. Top speed 42.5 MPH(ish). Quiet as a church mouse, and starts right up. I took a chance when I bought this engine, with no longevity history, but with a full warranty to 4/13/11, I figured I'd go for it. I have no regrets, and love this set-up.

E=TEC 90 on my 1985 Montauk burns less fuel than my old three cylinder 70 used to, gets up to 41+ mph, carries three adults and two big dogs with no issues swinging a 15inch stiletto prop. After some initial problems, I am so far pleased with the performance. So far no problems in colder weather. My only current issue with the motor is a cracked plastic lower cowling around two of the bolts that hold it on (this cowling has been removed several times)(one of these days I will get it back into the dealer and see what BRP has to say about that); also, those same bolts that hold the cowling together are not stainless so there is some corrosion.

As clarity returns....David correctly pointed out above the article which I referenced was in Saltwater Sportsman - Feb 1996 - A Honda rigged by Whaler on a '96 Montauk. Again, if anyone is interested in it, let me know & I'll fax it out.

David Jenkins posted 12-21-2004 08:00 PM ET (US)     Profile for David Jenkins  Send Email to David Jenkins     
So with one engine (the E-TEC 90) you can leave the splashwell unplugged, even with the battery in the stern and a 4-inch setback plate.

And with the other engine (the Honda 90) the drains to the splashwell are underwater, even with the battery in the console and no setback plate!

For me, this would be of great significance, especially since there are times that you will be using a live bait well and you may be loaded down with even more weight, such as extra fuel, 3 or 4 crew members, ice and gear. For safety reasons and to avoid nasty scum etc, I like to keep the spash well unplugged and dry at all times.

Let us know what you decide to do and how it works out.

Just a thought, If you are looking for speed and fuel performance, what about the Merc 115 fourstroke at 386 lbs.? This is the motor that I am considering. You can get it online at edsmarinesperstore.com for $6999 plus shiping.

I have a Merc 115 4-stroke EFI on my 2000 Montauk and think this is an excellent combination. Weight distribution and balance are always important on a small boat. The 115 4S purrs like a kitten and delivers very good low/high range operation. Lightly loaded (one person), trimmed properly, I reached 49.5 mph, GPS, with a 17" S/S propeller, at WOT. More importantly, cruising at 3500-4000 rpms will yield very good speed and economy. If you are planning on mounting a bait tank, it should be more mid-ship. If you are planning to mount a kicker motor on the transom, I would consider the E-TEC which would be lighter. If will not regret the Merc 115 4S, and, it you are a Californian, I believe all you can get would be a 4-stroke or DFI. Hope all this first hand info helps.

Dogfish2. Do you have your 115 4s on a jackplate? Also is your hull the old style montauk or the 170 montauk? Any info you may have would help.

Following up on a point raised above:

The classic MONTAUK 16-foot 7-inch hull is shown in the printed 2002 catalogue and is listed with a specified maximum engine weight of 410-lbs.

(Note that in the literature that year they referred to the classic 17-foot MOTAUK as the "170 MONTAUK", but this was prior to that name being applied to the new hull which was introduced in 2002, but after the catalogue for that year was printed.)

dogfish2 posted 12-28-2004 12:19 AM ET (US)     Profile for dogfish2  Send Email to dogfish2     
There is no jackplate on the transom of my Montauk, which is the older hull and not the 170 Montauk. I do have Lenco Trim Tabs which certainly assist with the boat's performance. But, they are not really necessary. I believe a jackplate would add more weight to the transom than I like, and make the total weight of the Merc (386 lbs) plus 35 lbs or so, around 420 lbs. Also, you really don"t need to enhance performance with the 115. The 386 lbs is not really a problem for the Montauk. The motor looks a lot larger than its counterparts because Merc uses the same cowling for its larger DFI motors. Not breathing oil/gas exhaust fumes is great. Please let me know if you need any more information.

Hi everyone,

I just read above that some of you use plugs in the splashwell is that correct ? And my second question is why ? Thirdly, Whaler when delivering a new boat in the 17 - 15 foot classic range would not send plugs for the splashwell. I am just cusrious as to why you would plug the well.

Another question for Dogfish2: Did you put the lenco trim tabs on because of the weight of the motor? Or just as a performance enhancer? Are they adjustable while in operation? Thanks.

The Lenco Trim Tabs were installed for performance. They are also great when running thru a cross-chop. The weight of the 115 Merc really isn't a problem, but with any light boat, balance and weight distribution are important. Glad to answer any other questions you may have.

A reliable source told me that E-Tec motors are just about to have a promotional 7 year warranty. He said to look for it in January 2005, coinciding with an infomercial. He said his E-Tec, which I got to see, outperformed everything on the water.
He also said that friends of his who are guides were having issues with the exhaust from 4 strokes, some being unable to complete all day fishing trips due to headaches, nausea, etc.
dogfish2 posted 01-03-2005 05:13 PM ET (US)     Profile for dogfish2  Send Email to dogfish2     
Sounds like those guides either need maintenance on their 4 strokes or new motors. Never heard of anyone with properly functioning, 3-star CARB rated motor having exhaust problems. That's great news concerning the extended warranty on the ETEC's.
ratherwhalering posted 01-04-2005 12:54 PM ET (US)     Profile for ratherwhalering  Send Email to ratherwhalering     
Curtis, that promotional warranty is probably similar to the one offered last year on the E-TEC. Purchasers were given the option of a cash rebate, or an additional 4 year extended warranty. The factory warranty is valid for 3 years, and thereafter a third party administrator (Premium Marine Protection) takes over. This is not an extended manufacturer warranty, but a "dealer warranty" that is administered by a third party. There is a $25.00 deductable for warranty repairs.

You are probably correct, though my source did not tell me that part. I called Sports Center in Perry GA, and was quoted under 7K for the 90 hp E-Tec Saltwater, but they had not heard of a 7 year warranty yet. I am thinking this motor is the best thing out there.

Honda dealers are in the mood to deal on 2004 models. Two months ago I bought a Honda 90 with rigging, cables and gauges for $7500. It was the best deal i could get from any of the AK. dealers including Yamaha, Suzuki, OMC and Merc. The transom sits a little lower than with 84 Seahorse but it is so quiet. Still playing with props but it seems like the 17 pitch is the ticket (44 mph at 5800 rpm WOT).

I think that Eds Marine has them listed for $6,299.00, plus shipping. Eds charges a large flat fee for shipping, which may make up for their low prices. (Strangely, the 75HP E-TEC is listed for $200.00 more than the 90HP.) Be careful to negotiate the warranty with the purchase price because I have heard that the listed price includes the cash rebate, which the dealer keeps. I believe there will be a cash rebate of $4.00 per HP, so a 90HP would allow for a $360.00 cash rebate. Thus, if you want the warranty, you will have to pay $6,299.00 plus $360.00 for the extended warranty, for a grand total of $6,659.00 plus shipping.

I got my 2004 E-TEC (saltwater edition, without prop or controls) from Custom Marine in Georgia for $6,215.00, with no sales tax, including the 7 year warranty. I paid $318.00 for shipping to California, for a grand total of $6,533.00 with extended warranty. (or $6,173.00 with the standard 3 year factory warranty, had I elected the $360.00 cash rebate.)

The same package from Eds would have been $6,299.00, plus $360.00 for the warranty, plus $450.00 for shipping for a total of $7,109.00.

There are deals out there, just make sure you ask about all the details. I hope this helps others recognize some of the pitfalls of purchasing an engine from a bargain volume dealer.

Wally...

So..I saw your post today. 2 years ago I repowered my 1989 Montauk and researched a ton. Here it is:

Had 1988 Yamaha 70 on boat. Sold it on the Internet for $1200.

For 2 stroke Japanese EFI:

Contacted Tohatsu, they would not sell a motor directly to a consumer w/o dealer install, so I dropped that.

Suzuki required new props and cables controls...Was costly and power would remain at 70, 90 too heavy.

Yamaha 90 4 stroke too heavy in my opinion. Too large for boat designed in the 70's.
Not interested in OMC or Merc...too many horror stories.

Honda same problem as Yamaha concerning weight.

So....I bought a Yamaha 90 hp 2 stroke from Ed's and picked it up myself. Installed it with a friend in an afternoon using old 70 control and new tach and wiring harness and kept my aluminum and SS props from the 70.

It has only 35 hours now and is just breaking in. Does 40mph+ weighs only 264 or so. Of course this is a non efi, non 4 stroke but is a tremendous amount of smooth power in a light, reliable, proven designed engine that has sold for as low as $4800 at Ed's. Tough to beat if you are ok with a rock-solid though 2 stroke carb design.

Crusing speed is at 3500rpm and fairly fuel efficient as long as you are not hitting 5500 often! (Though it does bring tears to my eyes at this speed in excess of 40mph!

Have fun...

FYI...Yamaha F60 with EFI now might be worth looking into (light and $5500 at Ed's) but still only a 60 anyway you slice it.

Jim.

Has anyone heard if the 90HP Mercury 4 strokes will be EFI or not? With the boat shows starting, I thought they might show up. I called Mercury about a month ago and they would not say yes or no, just "not at this time".

I see Jim found that the 2001 catalog called the classic Montauk 17, a 170 and listed its max motor weight as 410 lbs. I still think this applies to the newer hull, which was delayed for some reason to mid-model year.

I know many are running the classic with heavier motors, but I'd sure stick to the 90HP E-Tec, or lighter, and even at that, relocate the battery to the console if necessary.

I believe Mike Brantley found better overall pricing, including controls, at a source other than Ed's. Search for his E-Tec thread in the Performance forum archives.

Do yourself a favor and buy the motor it was made for. 4 strokes are too heavy for the older whalers.

There is not a perfect 4-stroke engine for the 15 or 16/17 hulls but the 40 and 50 hp Honda at 203 pounds is not too much weight for the 13 and the Suzuki 140 at 410 pounds is ideal for the classic 18, 19, and 21' Outrages.
