EJU37250Information display
The information display shows watercraft op-
erating conditions.
EJU37261Hour meter/voltmeter
The hour meter/voltmeter can be used as an
hour meter or a voltmeter.
TIP:
The hour meter is selected at the Yamaha
factory.
Hour meter
The hour meter shows the hours of engine op-
eration that have elapsed since the watercraft
was new.To switch to the hour meter from the voltme-
ter:
Push the “Hour Volt” button for at least 1 sec-
ond. The display switches from the voltmeter
to the hour meter.
Voltmeter
The voltmeter shows the battery voltage.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage has dropped significant-
ly, “LO” is displayed on the voltmeter. If the
battery voltage has risen significantly, “HI” is
displayed. If “HI” or “LO” is displayed, immedi-
ately return to shore and have a Yamaha
dealer service the watercraft.

ond. The display switches from the hour
meter to the voltmeter.
EJU37270Fuel level meter
The fuel level meter is provided for convenient
fuel level checking while riding.
The fuel level meter has four segments which
show the amount of fuel remaining in the fuel
tank. The display segments of the fuel level
meter disappear one at a time as the fuel level
decreases.
TIP:
The fuel level is most accurate when the wa-
tercraft is sitting level on a trailer or in the wa-
ter.
EJU37280Fuel level warning
If the fuel remaining in the fuel tank drops to
about 18 L (4.8 US gal, 4.0 Imp. gal), the low-
est fuel level segment, the fuel indicator, and
the “WARNING” indicator light blink, and the
buzzer sounds 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:
Push the “Hour Volt” button to stop the buzz-
er.
EJU37290Oil pressure warning
If the oil pressure drops significantly, the
“WARNING” indicator light and the oil pres-
sure warning indicator blink, and the buzzer
sounds intermittently. At the same time, the

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 23 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 72 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 24 for hood opening and closing
procedures.)
(2) Remove the seats. (See page 23 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 41 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 23 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-
