Removal
1) Remove the cotter pin from the propeller shaft and discard.
2) Wedge a piece of 1" x 4" wood between the propeller blade and the starboard side of
the strut and rudder.
3) Loosen the nylon locknut and unthread it until it is flush with the end of the prop
shaft.
4) Use a propeller puller to separate the prop from the taper on the shaft. Holding the
prop with one hand, remove the nylon locknut and discard.
5) Remove the propeller, then remove the key from the keyway. Inspect the keyways
and key for any damage.
Installation
Before installing the prop, look at the keyway on the shaft and in the propeller. The key
should slide freely in both keyways. DO NOT use the prop nut to advance the prop onto
shaft.
If the key has slight damage or burrs, remove them by filing the flat sides or replace the
key. DO NOT file the key beyond its normal shape or size.
1) Rotate the shaft until the keyway is "up."
2) Place the key in the shaft keyway. Align the keyway in the prop to the key. The prop
will only slip on in one direction. Once the prop starts to go on the shaft, push the
propeller "solidly" on the shaft and make sure you feel that it is seating properly.
3) Wedge a piece of 1" x 4" wood between the propeller blade and the port side of the
strut and rudder.
4) Install a new nylon locknut and torque the nut to maximum of 30 ft-lbs (40.7 N•m).
5) Install new cotter pin. Bend the retaining ends of the cotter pin in the opposite
directions. Make sure the cotter pin is snug and cannot rotate.
