SERVICING YOUR OUTBOARD MOTOR
Anode Replacement
The anodes are located on each side
of the gear case and on the stern
bracket. They are made of a
sacrificial material that helps to
protect the outboard motor from
corrosion.
Replace the anodes when they have
been reduced to about half their
original size, or if they are crumbling.
Painting or coating the anodes will
defeat their purpose and will lead to
rust and corrosion damage to the
outboard motor. The anodes must be
exposed to the water in order to
protect the outboard motor.
Propeller Replacement
Before replacing the propeller,
remove the emergency stop switch
clip from the emergency stop switch
to prevent any possibility of the
engine being started while you are
working with the propeller.

The propeller blades may have sharp
edges, so wear heavy gloves to
protect your hands.
Operating the outboard motor at
higher altitudes will reduce available
power. This may require decreasing
the propeller pitch to maintain correct
engine RPM.
Removal
1. Remove the cotter pin, unscrew the
castle nut, remove the 18.5 mm
washer, and then remove the
propeller and thrust washer.
2. Inspect the propeller shaft for any
fishing line or debris.
