WARNING
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.
