Impeller Removal and Installation

If the driveshaft 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 impeller, always shift outboard to neutral position and remove spark plug leads when
servicing the propeller.
REMOVAL
1. Shift outboard to neutral (N) position.
2. Remove spark plug leads to prevent engine from starting.
3. Remove the water intake housing that is fastened with six screws.
4. Straighten the bent tabs on the impeller nut retainer and remove the impeller nut.
