speeds. If this occurs, the “WARNING” light
and the engine overheat warning indicator
come on and the buzzer sounds continuously.
In addition, the warning system will cut the ig-
nition to the engine to reduce the risk of se-
vere overheating. The engine cannot be
started until it cools down, so it may be neces-
sary to have the watercraft towed back to the
shore. (See “Towing the watercraft” on page
78 for towing procedures.)
The warning signals will be cleared when the
engine is restarted after it has cooled down.
NOTE:
If multiple warnings occur at the same time,
their priority is as follows:
(1) Final engine overheat warning
(2) Fuel level warning
(3) Oil level warning
(4) Initial engine overheat warning
(5) Exhaust temperature warning
(6) Check engine warning

perature warning system.
If the exhaust temperature becomes too hot,
the “WARNING” light and the exhaust tem-
perature warning indicator begin to blink, and

return to shore to allow the exhaust system to
cool down.
WARNING
EWJ00830
Do not touch the hot muffler or catalytic
converter during or immediately after en-
gine operation; they can cause serious
burns. In addition, the catalytic converter
becomes hotter after the engine stops be-
fore cooling down.
CAUTION:
ECJ00810
This model is equipped with a catalytic
converter.

If the “WARNING” light, exhaust temper-
ature warning indicator, and buzzer
come on, reduce the engine speed (be-
low 4000 r/min) and return to shore.

If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe en-
gine damage.
The warning signals will be cleared when the
engine is restarted after it has cooled down.
