Ok the Yamagucci is running good. My center cyl is still down 10% compared to the other 2 but no biggie. Now....I came across a local dealer selling 99 ficht Evinrude 115's for $3500. He also has a 2001 Yamaha 115(might be a "c115") for $3100 that was used for a couple hours and guy decided on a 4 stroke instead. I think I have to do it, just on general principal. Any suggestions?

Can you get an aftermarket warranty for the 99's? You may also be able to finesse an upgrade on the 99's. I know you love a challenge.

He should GIVE you the 99 Ficht, from what I've heard! There's a reason why he still has a 3 year old engine.

Yamagucci 115 for $3100 has my vote. On the Monauk I think there is an advantage having the 115C in that you don't have a oil tank cluttering up your deck or taking up space in the console. So you burn a little more gas and have to stick oil in the gas tank, big deal.

Can a 115hp Yammie V4 fit on a Montauk? I would say that it's too big, both in weight and in Coast Guard allowable horse power.

I have a friend with a Yamaha 115c on a Montauk without any problems. Said it does 51 mph and he knows someone with a 130c that does around 60 mph. I think he had to mount the engine himself. ejb

Weight shouldn't be an issue, since this engine is about the same as a 75/80/90/100 four Stroke.

HP is not really issue in terms of the boat handling it, but may result in an insurance surcharge.

That Yammy 115 weighs 358#, Bigshot. I guarantee you severe porpoising problems. Not to mention the legal risks.

The J115 at closer to 300 would handle better, but 1999 is year two of the worst QC in OMC history. Don't overlook that dreaded phrase, "As is."

Well I bit the bullit! The 115 was NOT a C and was injected, but it was a 25" shaft(too bad). The fichts were 25"s too. Then the guy says how about a 70hp? Being I am not big on it having a 90hp I say can I see it? It was a BRAND NEW 1999 70hp Evinrude 4 stroke. No warranty but it has a prop and I paid $2855 for it, screw the warranty! I am looking into outside warranty contracts but it don't look good. JB we need to talk about your Zuki set up and how she does and what prop, etc. I am excited even though I stepped down 20hp, who cares. If I want to go fast I'll use the Baja. If I want to moon the gas stations, I'll take the 4 stroke. I will keep you all posted.

I've taken a ride in a 130hp Yammie Montauk. Damn fast and no noticeable problems. These engines actually carry less weight that some of the american V4's. That would be my choice, but then again I like speed. Good luck!

I have a 1986 115 hp Yamaha injected on 1971 Nauset. Works great since new. No porpoise. 49 mph. Had 1971 100 Johnson before that since new. Might be time for new engine.
fifteen year itch. bye

Oh man, I just lost my dinner! $2,855 for a 4-stroke 70hp Suzuki in an Evinrude box. Most excellent! Some guys have all the luck. I looked pretty hard for a "deal" on one of those. Nice job. Does she have any sisters?

I wish she did, I could make a fortune on E-Bay.

Nick, let me know if she'll pull you up on skis. I may have the line on an older Montauk that needs a repower. Regards, Jay P.S. Please strap a 25# weight on and I think you may be in my ballpark (225#).

22# weight. I have a nice 90 Yamagucci for sale!

JB - you mention above that the 358# Yamaha would cause porpoising problems on a Montauk.
I'm not sure this would be correct. Just don't want to mislead people.

For two years now, BW has been factory installing the Mercury 90HP 4 stroke on this boat, at 386#. Would they do this if porpoising could not be eliminated? I have also seen Montauks with Merc's in-line 4 100HP engine (now discontinued), which weighed 368#. Then there are those Montauks with a 300lb 90HP 2 stroke (OMC or MERC), carrying a kicker on the transom.

Ahoy, lhg. I appreciate your concern about not misleading people. I am sure you have followed the threads over the past few months that dealt with Montauk porpoising, and noted that most who have had the problem have a heavy 4 stroke aboard and porpoise before being able to reach max speed by trimming out.

Perhaps a shorter prop or simple discipline in not trimming out so far eases the problem, but I have also recieved the complaint from several Merc90 owners, including one that swapped for a DF50 Suzi to get rid of it (it did).

In my case, even though my Suzi only weighs 338#, it is on a 4" setback, which levers the weight up a notch or two.

Consequently, I expect a Montauk with over 300# on the transom to be at risk of porpoising at high speed, and I think it is a good idea to caution people about it, just as I caution people about the risks of overpowering, which a 115 Yammy would certainly do.

Bigshot - I picked up a 2000 70 HP Evinrude last year for $4500 with no prop and I love it on my Montauk. It seems to run as strong as the 90 Merc I replaced and weight is no problem. I run a 14 x 17 OMC prop and turn 5500 RPM at WOT. Enjoy...Bob M.

PS. When you mount it you will have to use the blind mounting holes on the bottom bolts.

PPS - I never porpoise, but then again I mounted the engine somewhat low...not "one hole up" as sometimes recommended to get maximum speed.
Bigshot posted 12-24-2001 09:45 AM ET (US)     Profile for Bigshot  Send Email to Bigshot     
I mount high. Is that prop you are running alum or SS. Mine has an alum and I will try it. My bud has a 17" alum off his 60hp Zuki that I can try too.
RWM posted 12-24-2001 10:01 AM ET (US)     Profile for RWM  Send Email to RWM     
The prop I use is aluminum. The Evinrude is set up to take the OMC prop. I think you might need some kind a special bushing for the Suzuki prop. There are several differences with the Evinrude vs. Suzuki. The electronics use the OMC system check, the alternator is different and also the control ends and fuel connector. Not sure about anything else...Bob M.

I called Bombardier and got the skinny. I then went to boaters surplus and got the controls w/key, wiring harness, and tach(all systemscheck OMC) For dirt cheap. Suzuki and OMC always had interchangeable props but like you said the OMC on Suzuki engine requires a thicker spacer. The Suzuki prop fits an OMC without. I had a Zuki ss prop on my 70 Johnson. I have an extra 13x17 OMC alum laying around also. If 17" is good I will have my 17" SS Yamaha prop rehubed to fit OMC for like $50. Just have to sell my Yamaha so I can mount this and see. I will ask questions later. Happy Holidays!
