7. OPERATION (MOTOR PROTECTION SYSTEM)
Over-Rev Limiter
This outboard motor is equipped with
an engine over-rev limiter which
activates when the engine speed
increases excessively. The over-rev
limiter can be activated while cruising,
or when ventilation occurs during a
sharp turn.
When the over-rev limiter is activated:
1. Reduce the throttle opening immedi-
ately and check the motor angle.
2. If the motor angle is correct but the
over-rev limiter stays activated, stop
the engine and check the condition
of the outboard motor and check the
propeller for damage. Correct or
service as necessary.
Anode

which helps to protect the outboard
motor from corrosion.

anode will lead to rust and corrosion
damage to the outboard motor.
There is a small sacrificial anode in the
water passages of the engine block.
