You also need to verify if the propeller hub size (hole in the center) fits your motor propeller shaft. Nearly all 4″, 5″ and 6″ propellers are designed for 5mm shafts. Webb25 dec. 2013 · A lot depends on what propeller diameter you are starting with. For example: if you start with a 14 inch diameter prop and go up to a 15 diameter prop, keeping the same pitch, the effective prop 'area' (discounting the hub) increases by over 15%. You could expect a 15% decrease in RPM.
