To run E85, yes you do need to re-jet your carbs. Depending on the engine you may need to upgrade your fuel system, because you need to burn approximately 30% more at the same power level.
It would not be good for your run of the mill motors. People running 1000 hp engines on race gas, though, could save a lot of money running E85.
Fuel vaporization with Ethanol varies a lot due to temperature, which might require some re-tuning. I would think that the range of temperatures boats operate in would be constant enough to come up with a "good enough" tune, though. Plus even high hp boat motors aren't as close to the ragged edge as alcohol drag cars.
