CONTROLS AND FEATURES
COOLING SYSTEM INDICATOR
TAKING CARE OF UNEXPECTED
PROBLEMS
Water should flow from the cooling
system indicator while the engine is
running. This shows that water is
circulating through the cooling
system.
The engine is equipped with an
overrev limiter to prevent the
possibility of mechanical damage
from excessive engine speed.
The overrev 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 overrev limiter is activated,
check the trim angle of the outboard
motor.
The cooling system indicator
discharge port can also become
plugged.
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. Refer to
