EJU43901Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator, the
check engine warning indicator, and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. After 5 sec-
onds, the engine overheat warning indicator
and the “WARNING” indicator light stop
blinking and remain on, and the buzzer
sounds continuously. After 30 seconds, the
buzzer stops. While the engine overheat
warning is activated, the maximum engine
speed is limited.
If the engine overheat warning is activated,
immediately reduce the engine speed, return

being discharged from the cooling water pilot
outlet while the engine is running. If there is
no discharge of water, stop the engine, and
then check the jet intake for clogging. (See
page 106 for information on the jet intake.)
NOTICE: 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.
