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.
The cooling system indicator
discharge port can also become
plugged.
The engine is equipped with an
overrev limiter to prevent the
possibility of mechanical damage
from excessive engine speed.
The anodes are made of a sacrificial
material that helps to protect the
outboard motor from corrosion.
There are two anodes on the gear
case, one on the stern bracket and
two small anodes in the water
passages of the engine block.
The overrev limiter may be activated
during operation, limiting engine
speed, if the outboard motor is
trimmed or tilted up excessively, or
when propeller ventilation occurs
during a sharp turn.
If the overrev limiter is activated,
check the trim angle of the outboard
motor.
Check to see if the correct propeller
is installed.
