I don't disagree with anything that's been said so far - everybody has
made great points. But I'm firmly in the camp of horsepower vs rpm.

With less horsepower, all else being equal, it makes sense to me that
the engine will transmit less direct power to the prop, thus more
slippage, thus less speed.

Well, this is fine how-do-you-do! We disagree.

The magic part of this exercise is the 6000 RPM. Again, all else equal,
including prop pitch, both boats are going to move the same distance in the
same time.

The bigger engine will get to 6000 RPM faster ... and *it* will probably
produce more prop slip in the process. Not unlike burning rubber in your
Vette. Get fatter or sticky-er tires and your slippage will decrease.
