8. Propeller Installation

The propeller fits onto the engine‘s crankshaft. If it does not fit, use a propeller reamer, tapered reamer to open the hole slightly. Do NOT oversize the hole. Once the propeller has been positioned on the shaft, use the spinner nut to retain the propeller. To tighten the nut, slide a screwdriver or other device through the hole in the end of the nut.
