Be carefull w/ putting a lot of hp into a boat that was not designed for it.
I/O type boats - if overpowered - will run sideways due to the torque of the
engine. The boat is just not designed hull wise for a big hp/torque power
plant.
They come w/ V8 but at about 250 hp or so. If you put 400+ hp in it you may
find that it does not run straight.

On a typical I/O single(Mercruiser, Volvo SX, Cobra), facing the stern
from outside the boat, the engine is turning ccw, and the prop(single,
again) is turning cw... so I really don't understand your statement - is
it torque from the prop or from the engine? If it's the engine, what is
the moment?

Rob

It is really fom the prop. You would be turning a lot bigger pitch prop
than stock which will pull on the boat more than the hull can support.

===============

Easily fixable with trim tabs in my experience.

Which creates drag and partially defeats the purpose of more hp.

I'm doing low 60's in my 5.7 19.5" and it tracks straight. A little
squirley in light chop at that speed. Definately not a boat for rough water
though, pounds like hell. I think with a little more prop I could get to
65. Or a blower :-)

I bought a brand new 23' Stingray about 10 years ago. It was a fast
boat, but it was built too light, and suffered accordingly. Read my
full review he

I had a buddy that had a 19ft rs? Bowrider with the Z-Plane hull. with a
4.6 V6 the thing would do around 50mph. But it pounded any waves it hit.
One of the hardest riding boats I was ever on. The botton was pretty
flat. I have no idea what the deadrise was.

That's what I like about the Stingray... a 50 MPH boat with just the 4.3
liter. On our little pond, the hull would be fine.

Yep most boats have a enviroment that suits them well. If lots of big
boat wakes are not a problem the one my buddy had would be great, on gas
preformance etc. Lake Lanier was not a good home for it :-)
