...interesting thought here....
I buddy (here on the forums) races hydroplanes. He runs a 2.6/2.7 litre 12 valve V6 Alfa Romeo engine on a methanol/alcohol mix and 14:1 compression making about 330 horses...
Any event, one of the problems that he was faced with was that the engine turns in the wrong direction for the carve direction that most (all) boat propeller manufacturers cuts there blades to...
Randy solved the problem by building a nose-drive for the crank-pulley end of the motor and now he runs it BACKWARDS in the hull!!!
Spin that S2000 around!!!
Cool project by the way.
