Over-Rev Limiter
This outboard motor is equipped with
an engine over-rev limiter which limits
the maximum engine rpm. This over-
rev limiter protects the engine from
mechanical damage.
The over-rev limiter may be activated
by putting the propeller in a light load
condition or propeller ventilation.
When the
over-rev
limiter
is activated,
the engine rpm will become unstable
or erratic. Should this occur, reduce the
throttle opening and wait for the
engine rpm to stabilize, then increase
the
throttle opening.
On the power trim/tilt type motors
lower the trim angle on high speed
turns to reduce the possibility of
propeller ventilation.
If the over-rev limitter activates when
trim/tilt angle is correct, stop the
engine and check for mounting
problems and propeller damage.
If mounted improperly, fix it.
If the propeller is damaged, replace it.
