NOTE:
Before applying grease through the steering
bracket grease nipple, lock the motor in the fully
tilted up position.
ANODES AND BONDING WIRES
Anodes
The motor is protected from exterior corrosion
by anodes. These pieces of anodes control
electrolysis and prevent corrosion. The anodes
will corrode in place of the parts they are pro-
tecting. You should periodically inspect each of
the anodes and replace them when 2/3 of the
metal has corroded away.

NOTE:
Consult your authorized Suzuki Marine Dealer
for inspection and replacement of internal
anodes attached to the cylinder block/cylinder
head.
Bonding wires
Bonding wires are used to electrically connect
the engine components so they exist in a com-
mon ground circuit. This allows them to be pro-
tected against electrolysis by the anodes.
These wires and their terminals should be
checked periodically to be sure they have not
been damaged.
NOTICE
If anodes are not properly maintained, under-
water aluminum surfaces (such as the lower
unit) will suffer galvanic corrosion damage.
• Periodically inspect anodes to make sure
they have not become detached.
• Do not paint anodes, as this will render
them ineffective.
• Periodically clean anodes with a wire brush
to remove any coating which might
decrease their protective ability.
