EJU31090Fuel tank filler cap
To remove the fuel tank filler cap, turn it coun-
terclockwise.
NOTE:
Make sure that the fuel tank filler cap is se-
curely closed before operating the watercraft.
EJU36270Remote control transmitter
The lock and unlock modes of the Yamaha
Security System are selected using the re-
mote control transmitter. (See “Yamaha Se-
curity System ” on page 33 for information on
using the remote control transmitter.)
CAUTION:
ECJ00930
The lock and unlock modes of the Yamaha
Security System can only be selected us-
ing the remote control transmitter. Ob-serve the following precautions to protect
your remote control transmitter:

Store the remote control transmitter
carefully so it will not be lost. When op-
erating the watercraft, use the transmit-
ter holder in the watertight
compartment. If you accidentally lose
your remote control transmitter, contact
a Yamaha dealer.

While the remote control transmitter has
been designed for use in wet environ-
ments, it should not be operated under-
water or submerged for an extended
length of time. If it gets wet, dry it with a
soft, dry cloth.

Keep the remote control transmitter
away from high temperatures and do not
place it in direct sunlight.

Do not drop the remote control transmit-
ter, subject it to strong shocks, or place
any heavy items on it.

Use a soft, dry cloth to clean the trans-
mitter. Do not use detergent, alcohol, or
other chemicals.

If the remote control transmitter needs a
new battery or is not operating properly,
contact a Yamaha dealer. Do not attempt
to replace the battery yourself.

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.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.

the water is discharged from the electric bilge
pilot outlet at the stern.
A small quantity of water will remain in the
bilge and should be drained manually. To
drain any residual water, beach the watercraft
and perform the following procedure.
CAUTION:
ECJ00350
If starting the engine after the watercraft
has capsized, do not operate the engine at
full throttle when water is being dis-
charged from the electric bilge pilot outlet
at the stern. Excessive water in the bilge
can splash into the engine, which can re-
sult in severe damage.
To drain water from the bilge:
(1) Remove the stern drain plugs.
(2) Raise the bow of the watercraft until the
water drains.
(3) After the water has drained, wipe the
bilge with dry rags to make sure that it is
thoroughly dry.
(4) Install the stern drain plugs.
CAUTION:
ECJ00360

Before installing the stern drain plugs,
clean the drain plug threads to remove
any foreign materials, such as dirt or
sand. Otherwise, the stern drain plugscould be damaged, allowing water to en-
ter the engine compartment.

Make sure that the stern drain plugs are
tightened securely before launching the
watercraft. Otherwise, water may flood
the engine compartment and cause the
watercraft to submerge.
EJU32470Stern drain plugs

the battery. Fire or explosion could re-
sult if the breather hose is damaged, ob-
structed, or not connected properly.
Make sure that the battery is securely held in
place.
EJU32580Fire extinguisher
