If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 51
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is re-
started.
EJU43720Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator, the check engine
warning indicator, and the “WARNING” indi-
cator light blink, and the buzzer sounds inter-
mittently for 30 seconds. At the same time,
the maximum engine speed is limited.
If the oil pressure warning is activated, imme-
diately reduce the engine speed, return to
shore, and then check the engine oil level.
(See page 53 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
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 overheatwarning is activated, the maximum engine
speed is limited.
If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is
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 95 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.
