Features and functions
35
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.
EJU31550Hour meter/voltmeter
NOTE:
To switch the display between the hour meter
and the voltmeter, push the select button for
at least 1 second after the meter is displayed
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.
EJU31560Fuel 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” light
begin to blink. The buzzer also starts sound-
ing 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.

If the oil pressure does not rise to specifica-
tion, the “WARNING” light and the oil pres-

Operation
45
EJU32280Pre-operation check points EJU32310Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seat. (See page 26 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.
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.
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.
EJU32390Fuel level
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
73 for check points and correct procedures.)
(1) Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.(2) Remove the seat. (See page 26 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 42 for
filling procedures.)
(4) Install the fuel tank filler cap and the seat.
EJU32400Engine oil level
Check the engine oil level before each use.
CAUTION:
ECJ00390

When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and wind can cause the
watercraft to move and lead to a colli-
sion.

When checking the engine oil level on
land, supply water to the cooling water
passages. (See page 66 for procedures
on supplying water.)

Make sure that the engine has enough
oil, but do not overfill it. If there is too lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter can be-
come saturated with oil, permanently
damaging the filter and reducing engine
performance. Follow the checking pro-
cedure carefully.

Make sure that debris and water do not
enter the oil tank 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 horizontal posi-
tion or launch the watercraft, and then
start the engine.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.

Maintenance and care
74
CAUTION:
ECJ00190
If oil is leaking or the oil pressure warning
indicator comes on when the engine is
running, immediately shut the engine off
and have a Yamaha dealer check the wa-
tercraft. Continuing to operate the engine
under such conditions could cause severe
engine damage.
EJU34310Air filter element
Have a Yamaha dealer check and clean or re-
place the air filter element every 12 months or
every 100 hours of operation.
EJU34320Checking the jet thrust nozzle angle
Check the handlebars and jet thrust nozzle for
smooth operation.
Turn the handlebars as far as possible to the
right and left and check that the difference of
distances A and B between the jet thrust noz-
zle and the nozzle is within specification.
If the steering is stiff or misadjusted, have a
Yamaha dealer service it.
EJU34350Checking the shift cable (for VX
Deluxe/VX Cruiser)
Place the shift lever in the reverse position.
Make sure that the reverse gate makes con-
tact with the stopper.Difference of A and B:
Maximum 5 mm (0.20 in)
