Depending on the engine crankshaft size, the propeller may need tobe reamed to a larger size using GPMQ5005 (SAE) orGPMQ5007 (Metric).
Four-stroke engines are typically higher torque engines and shoulduse the larger props indicated in the range.Recommended prop ranges will vary depending on your particular engineand airplane.The Chart below represents average prop usage and should be used asOnly a General Guideline.
