To go back to the original post. The reduction gear is determined by 3 things: prop diameter, engine rated rpm and intended hull speed. Prop diameter is the biggest factor. Depending on the number of blades and blade design, the diameter will limit the speed the prop can turn. All props have a maximum blade tip speed (in feet per second) that they can turn before cavitation occurs. The new Acme props have been able to increase this for a given size. Hydrodynamics is fascinating stuff!

Re: V drive question
Thanks, I think I have it now. A Velvet drive has the engine facing forward with a tranny and a shaft going straight to the stern-is that correct?

Re: V drive question
Inline, conventional, straight drive are all names for drives where the transmission bolts to the back of the engine and has a prop shaft running through the bottom of the boat, through a strut, with a prop on the end.
Velvet drive, paragon, hurth, twin disc are all brands of transmissions. Some also make v drives.
