level decreases.
TIP:
The fuel level is most accurate when the wa-
tercraft is sitting level on a trailer or in the wa-
ter.
EJU35061Hour meter/voltmeter 
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.
EJU36811Fuel level warning indicator 
If the fuel remaining in the fuel tank drops to
about 18 L (4.8 US gal, 4.0 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.
TIP:
Press any button on the multifunction informa-
tion center to stop the buzzer.

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 56 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.
TIP:
Press any button on the multifunction informa-
tion center to stop the buzzer.
EJU36821Engine overheat warning indicator 
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the “WARN-
ING” indicator light and the engine overheat
warning indicator blink, and then come on.
The buzzer also begins to sound intermittent-
ly, and then it sounds continuously. After the
light and indicator start to blink and the buzzersounds, the engine speed is limited to help
prevent damage.
If this occurs, immediately reduce the engine
speed, return to shore, and then check for wa-
ter discharge at the port (left) cooling water pi-
lot outlets 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. (See page 95 for more informa-
tion.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-
ate at higher speeds could result in severe
engine damage.

EJU32280Pre-operation check points EJU32331Engine compartment 
WARNING
EWJ00460
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak or
a loose electrical connection.
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seats. (See page 25 for seat removal and
installation procedures.) Leave the engine
compartment open for a few minutes to allow
any fuel vapors to escape.
While the engine compartment is open, check
for loose electrical connections.
EJU32350Hull and deck 
Check the hull and deck for cracks and other
damage. If any damage is found, have a
Yamaha dealer repair the watercraft.
EJU36871Fuel level 
Make sure that there is sufficient fuel in the
fuel tank before each use.
Also, check the fuel system for leakage,
cracks, and malfunctions. (See page 83 for
check points and correct procedures.)
(1) Open the hood and remove the fuel tank
filler cap to release any pressure thatmight have built up in the fuel tank. (See
page 26 for hood opening and closing
procedures.)
(2) Remove the seats. (See page 25 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 52 for
filling procedures.)
(4) Install the fuel tank filler cap, and then
close the hood and install the seats.
EJU36882Engine oil level 
Check the engine oil level before each use.
WARNING
EWJ00340
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ01001
Make sure that debris and water do not en-
ter the oil filler hole. Debris and water in
the engine oil can cause serious engine
damage.
To check the engine oil level:
(1) Place the watercraft in a precisely level
position on land with the engine stopped.
TIP:
If the engine was running, allow the engine oil
to settle by waiting 5 minutes or more before
checking the oil level.
(2) Remove the seats. (See page 25 for seat
removal and installation procedures.)
(3) Remove the dipstick, wipe it clean, and
then insert it back into the dipstick tube
completely. Remove the dipstick again
and check that the engine oil level is be-
