"engine rpm, reduction ratio, prop size?" Are really matters for a NA, a 
designer, or a propeller manufacturer. Michigan Wheel has an online program 
that can be of some help. Start with the largest prop that achieves the 
proper tip clearance on your boat and work back to the reduction gear and 
engine horsepower. The lower the engine rpm the better.
