When the motor is out of the water,
being transported, or in storage, always
remove the negative (-) battery cable to
prevent accidental starting of the
engine. Accidental starting when the
motor is out of the water will cause
water pump failure, overheating and
damage to the engine due to a lack of
cooling water.

DO NOT disconnect the electrical har-
ness when operating the motor. This
model will continue to run and can be
started with the electrical harness dis-
connected. Remove all spark plug con-
nectors from the spark plugs when
servicing the engine or propeller.
When your outboard motor i s in s torage,
thi s i s a good opportunity to have it s er-
viced or overhauled by your dealer.
