maximum engine speed is limited.
If the oil pressure warning is activated, imme-

shore, and then check the engine oil level.(See page 45 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.

formation center to stop the buzzer.
EJU31609Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. Then, the en-
gine overheat warning indicator and the
“WARNING” indicator light stop blinking and
remain on, and the buzzer sounds continu-
ously. At the same time, 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 be-
ing 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
84 for information on the jet intake.) NOTICE:
If you cannot locate and correct the cause
of the overheating, consult a Yamaha deal-
er. Continuing to operate at higher speeds
