Re: Re-power SUPER SPORT 15 with 115-HP

I agree with the post above. I have the same boat and engine, a 1988 15 with a Yamaha F70. I know plenty of people who have wanted to get more speed out of a 15. And while I understand the fascination with having a little 'hot rod' on the water, the hull in its original design is just not meant for ...

I have to play the devil's advocate here. From my understanding, this 60 E-TEC H.O. is merely a de-tuned 75-HP--or an even more, a de-tuned 90-HP. With the exact same weight, how would those motors work? I think you'd be looking conservatively at 20 more horsepower for the 90, which is a lot on a li...
