Engine overheat warning system
This model is equipped with an engine over-
heat warning system. If the engine starts to
overheat, “Engine Over Temp” will appear on
the LCD. The buzzer also begins to sound.
The engine speed is automatically limited to
help prevent damage. If this occurs, immedi-
ately reduce the engine speed, return to shore
or maneuver to a safe location, and check for
water discharge at the cooling water pilot out-
let.
There is a cooling water pilot outlet on the
starboard side of the hull. Check that water
comes out of the outlet while the engine is
running, particularly while applying throttle. If
you do not see any water at the outlet, cooling
water may not be circulating in the engine.
1 Cooling water pilot outlet
TIP:
If cooling water passages in the engine are
dry, it will take about 20 seconds for water to
reach the pilot outlet after starting.
If water is not circulating, something may be
clogging the intake grate. Refer to “Jet pump
clean-out procedure” on page 123.

NOTICE
If the cause of overheating cannot be
found and corrected, take special precau-
tions to avoid major engine damage while
you return to shore.
If getting a tow from another vessel is not
possible, operate engine just slightly
above idle while you return to shore. If you
can be towed, refer to “Towing the boat”
on page 126.
TIP:
Press either the M or T button on the multi-
function tachometer to stop the buzzer.
