Too blunt? Sorry, Yamaha is known for pushing the low end of the 10% variance on their engines' HP ratings!

Malcolm Tucker : He knows about motors?
Gomer Pyle : He hopped up an old V8 engine, put it on his rowboat. That thing'll do eighty. Now that's fast on water.

I mentioned the Aquasport experience because it was a bigger boat. From what I looked up just now, it was about 600 pounds heavier than the 20’ SeaCraft and it was almost there with a dead engine weight on the rear. Obviously, it’s not going to be a speed machine, but maybe doable for what one wants to do.
