The fuel level meter has eight segments
which show the amount of fuel remaining in
the fuel tank.
NOTE:
The fuel level is most accurate when the wa-
tercraft is sitting level on a trailer or in the wa-
ter.
EJU35060Hour meter/voltmeter
NOTE:
To switch the display between the hour meter
and the voltmeter, push the “Volt/Hour” button
for at least 1 second after the meter is dis-
played for more than 10 seconds.
Hour meter
The hour meter is provided to make it easy to
follow the maintenance schedule.The meter shows the hours of engine opera-
tion that have elapsed since the watercraft
was new.
Voltmeter
The voltmeter is provided to display the volt-
age of the battery.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage is less than 8.0 volts,
“LO” is displayed on the voltmeter and if the
voltage is above 18.1 volts, “HI” is displayed
on the voltmeter. If “HI” or “LO” is displayed,
return to shore and, if necessary, have a
Yamaha dealer check the charging system
and the battery.
EJU35072Fuel level warning indicator
If the fuel remaining in the fuel tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the low-
est two fuel level segments, the fuel level
warning indicator, and the “WARNING” indi-
cator light begin to blink. The buzzer also
starts sounding intermittently.
If this occurs, refill the fuel tank as soon as
possible.
The warning signals will be cleared when the
engine is restarted after the fuel tank is re-
filled.

EJU35122Oil pressure warning indicator
If the oil pressure does not rise to specifica-
tion, the “WARNING” indicator light and the oil
pressure warning indicator begin to blink, and
the buzzer sounds intermittently. At the same
time, the engine speed is limited to help pre-
vent damage.
If this occurs, reduce the engine speed, return
to shore, and then check the engine oil level.
(See page 53 for engine oil level checking
procedures.) If the oil level is low, add enough
engine oil to raise it to the proper level. If the
oil level is sufficient, have a Yamaha dealer
check the watercraft.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.
EJU36401Engine overheat warning indicator
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the engine
overheat warning system will be activated
and, in some cases, the warning system will
cut the ignition to the engine.
If the “WARNING” indicator light and the en-
gine overheat warning indicator begin to blink,
and the buzzer sounds intermittently, immedi-ately reduce the engine speed and return to
shore.
If the “WARNING” indicator light and the en-
gine overheat warning indicator come on, and
the buzzer sounds continuously, the warning
system will cut the ignition. The engine cannot
be started until it cools down, so it may be
necessary to have the watercraft towed back
to the shore. (See “Towing the watercraft” on
page 97 for towing procedures.)
After the engine cools down, start the engine,
and then check for water discharge at the port
(left) cooling water pilot outlet while the engine
is running. If there is no discharge of water,
shut the engine off, and then check the intake
grate and impeller for clogging.
WARNING
EWJ00050
Before attempting to remove weeds or de-
bris from the intake grate or impeller, shut
the engine off and remove the clip from the

engine shut-off switch. Severe injury or
death could result from coming in contact
with the rotating parts of the jet pump.
CAUTION:
ECJ00951
If you cannot locate and correct the cause
of the overheating, consult a Yamaha deal-
er. Continuing to operate at higher speeds
could result in severe engine damage.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.
EJU36321Exhaust temperature warning indicator
This model is equipped with an exhaust tem-
perature warning system.
If the exhaust temperature becomes too hot,
the “WARNING” indicator light and the ex-haust temperature warning indicator begin to
blink, and the buzzer sounds intermittently.
If this occurs, reduce the engine speed and
return to shore to allow the exhaust system to
cool down.
CAUTION:
ECJ00960
This model is equipped with a catalytic
converter.
If the “WARNING” indicator light, exhaust
temperature warning indicator, and buzzer
come on, reduce the engine speed (below
6000 r/min), return to shore, and have a
Yamaha dealer check the watercraft.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.
EJU35131Check engine warning indicator
