Gear Drive Ratio

This is basically a question for WaterThunder, but other opinons are more than welcome. I'm leaning towards purchasing one of your aluminum powerplants and I want to know what ratio of gear drive you recommend. I thought I saw a post a while back where you recommended a 2.37, but I can't remember what motor you were referring to. Also what kind of prop and how many blades?? I want to put it on a 14 X 8 aluminum hull and run dry with about 4 people. Thanx........
 
waterthunder, in older posts you made mention of the gear drive being a torque multiplier..if you dont mind could you explain the basics??
it seems easy to understand with a 2-1 if a engine is turning 5200
then the prop would be at 2600 rpm....then does the that double torque?
a small block would go from 350 to 700 ft pounds? is that why everybody with belt drives spins bigger props?


thanks for your patience
