Instructions
Remove the spinner retaining screw with a Phillips head screwdriver and pull the spinner off the tip of the propeller.
Hold the propeller in one hand to keep it from spinning and use a crescent wrench to loosen and remove the lock nut and the attaching nut from the end of the propeller shaft.
Slide the old propeller off and then slide the new one onto the propeller shaft.
Thread the attaching nut onto the propeller shaft by hand. Grasp the propeller and then tighten it with the wrench. Hand thread the lock nut back in place and tighten it with the wrench.
Set the spinner in place at the tip of the propeller shaft, making sure to line up the screw holes. Replace the screw with the screwdriver.
