Fuel meter
The fuel meter is provided for convenient
fuel level checking while riding. The fuel
meter has eight segments which show the
amount of fuel remaining in the fuel tank.
NOTE:@ The fuel level is most accurate when the
watercraft is sitting level on a trailer or in the
water.

Hour meter/Voltmeter
NOTE:@ To switch the display between the hour
meter and voltmeter, push the “Vo l t / H o u r”
button 1 for at least 1 second after the
meter is displayed for more than 10 sec-
onds.
@
Hour meter
The hour meter is provided to make it
easy to follow the maintenance schedule.
The meter shows the hours of engine
operation that have elapsed since the water-
craft was new.
Vo l t m e t e r
The voltmeter is provided to display the
voltage of the battery.
When the battery voltage is normal, the
voltmeter 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.

cator light all begin to blink. The buzzer also
starts sounding intermittently.
The warning signals will be cleared when
the engine is restarted after refilling.
NOTE:@ Press any button on the multifunction meter

Fuel and oil
This watercraft is equipped with a
4-stroke engine. Conventional 2-stroke
engine oil cannot be used.
The engine utilizes an electronic fuel
injection system to deliver the optimal air-
fuel mixture ratio required by the engine.
With optimal combustion conditions, this
system is able to increase startability and
improve fuel economy.
EJU19112
Gasoline
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!
Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.
Stop engine before refueling.
Refuel in a well-ventilated area with
the watercraft in a horizontal position.
Do not stand or sit on the watercraft
while refueling in case of fire.
Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.
Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level reaches approx-
imately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do
not leave it in direct sunlight. Leave it
in a well-ventilated area with the water-
craft in a horizontal position.

Tighten the filler cap securely after
refueling.
If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.
If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
CAUTION:@ Use only fresh gasoline that has been
stored in clean containers.

EJU18320
Gasohol
There are two types of gasohol: gasohol
containing ethanol and that containing meth-
anol.
Gasohol containing ethanol can be used
if ethanol content does not exceed 10% and
the fuel meets minimum octane ratings.
Gasohol containing methanol is not rec-
ommended by Yamaha because it can
cause fuel system damage or engine perfor-
mance problems. Recommended gasoline:
Regular unleaded gasoline with a
minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)
