Answer: OK, the propeller should be tuned to the engine, allowing the engine RPM to be in the proper operating range at Wide Open Throttle. A gear reduction transmission changes this ratio, while lowering the RPM for reduces fuel use. Could you give me the HP (should be 185) Max RPM (should be 4400) gear reduction (on transmission tag) and the speed you would like to cruise. Your 13/10’s are small, a better prop for best efficiency and performance will come from this design information. We may be able to use a 4 blade for reduced vibration or the standard 3 blade may work just as well.
