Cooling System Indicator

COOLING SYSTEM
INDICATOR
Water should flow from the cooling
system indicator while the engine is
running. This shows that water is
circulating through the cooling
system.
If water stops flowing while the
engine is running, that indicates a
cooling system problem, such as
clogged water intakes, which will
cause engine overheating.

OTHER FEATURES

Rev Limiter

The engine is equipped with a rev
limiter to prevent the possibility of
mechanical damage from excessive
engine speed.
The rev limiter may be activated
during operation, limiting engine
speed, if the outboard motor is tilted
excessively, or when propeller
ventilation occurs during a sharp turn.
If the rev limiter is activated, check
the tilt angle of the outboard motor.
Improper propeller selection may also
cause the rev limiter to activate.
Check to see if the correct propeller is
installed.
CONTROLS AND FEATURES

Anode

The anode is made of a sacrificial
material that helps to protect the
outboard motor from corrosion.
There is an anode on the
antiventilation plate.
