I've got the 2.68 ratio with < 400hp on motor and swing a 80" two blade SW around the 2mark turning 5k. Hull is 13'. what hull are you running?

Depends on the size of boat you want to put it on. How much weight are you trying to push? Was your engine built for an airboat or is it a pull out from a car or truck?
