Purging Air From the Engine Oil Tank

IMPORTANT: DTS helm configuration must be completed before performing the
following procedure.
1. Loosen the fill cap on the engine oil tank.
2. Start the engine.

Propeller Installation

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.
