Propeller Replacement ‑ 108 mm (4 ‑ 1/4 in.) Diameter Gearcase
If the propeller shaft is rotated while the engine is in gear, there is the possibility that the engine will crank over
and start. To prevent this type of accidental engine starting and possible serious injury caused from being struck
by a rotating propeller, always shift outboard to neutral position and remove spark plug leads when you are
servicing the propeller.
1. Shift outboard to neutral (N) position.
2. Remove spark plug leads to prevent engine from starting.
3. Straighten the bent tabs on the propeller nut retainer.
4. Place a block of wood between gearcase and propeller to hold propeller and remove propeller nut.
5. Pull propeller straight off shaft. If propeller is seized to the shaft and cannot be removed, have the propeller
removed by an authorized dealer.
