If the overheat warning is ignored, engine
and exhaust system heat may increase, par-
ticularly if the watercraft is operated at
higher speeds. When this occurs, the warn-
ing light, the engine overheat warning indi-
cator and the buzzer will change from
intermittently to continuously on, and the
overheat system will stop ignition to the
engine to reduce the risk of severe over-
heating. The engine cannot be started until
it cools down, so it may be necessary to
have the watercraft towed back to the
beach. (See “Towing the watercraft” on page
5-7 for towing procedures.)
NOTE:@ Press the select button on the multifunction
information center to stop the buzzer.

Exhaust temperature warning
system
This model is equipped with an exhaust
temperature warning system.
If the exhaust temperature gets too hot,
the warning light and exhaust temperature
warning indicator begin to blink, and the
buzzer sounds intermittently.
When this occurs, reduce engine speed
and beach the watercraft to allow the
exhaust system to cool down.
WARNING@ Hot muffler surfaces can cause serious
burns. Do not touch any muffler surface
during or after engine operation. The cat-
alytic converter gets hotter after the
engine stops.

CAUTION:@ Do not run the engine over 4,000 r/min
to check the meter for operation on
land. The engine could overheat or the
catalytic converter could result in seri-
ous damage.
Use the specified resistor-type spark
plug and cap, otherwise the meter may
function erratically.

NOTE:@ All display light up and the buzzer sounds
twice after the engine starts. Then, the

meter and voltmeter, push the select
button1 for at least 1 second after the

@
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.
The voltmeter displays 12 volts or more
when the battery voltage is within specifica-
tion.
If the voltage displayed is low, beach the
watercraft and, if necessary, have a Yamaha
dealer check the charging system.

Fuel warning indicator
If the fuel remaining in the tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the
lowest two fuel level segments, the fuel
warning indicator and the warning light
begin to blink. The buzzer also starts sound-
ing intermittently.
The warning signals will be cleared when
the engine restarts after refilling fuel.

Oil warning indicator
If the oil remaining in the tank drops to
about 1.7 L (0.45 US gal, 0.37 Imp gal) or
the oil filter is clogged, the oil warning indi-
cator and the warning light begin to blink.
The buzzer also starts sounding intermit-
tently.
If the oil warning indicators begin to blink,
refill with engine oil as soon as possible.
The warning signals will be cleared when
the engine restarts after refilling engine oil.
NOTE:@ If the warning indicators blink with adequate
oil in the tank, have a Yamaha dealer check
the oil filter for dirt and clogs.

Check engine warning
indicator
If a sensor malfunction or a short circuit is
detected, the warning light and indicator
begin to blink and the buzzer sounds inter-
mittently.
If this occurs, reduce the engine speed,
beach the watercraft, and have a Yamaha
dealer check the engine.

Engine overheat warning
indicator
If the engine starts to overheat, the warn-
ing light and engine overheat warning indi-
cator begin to blink, and the buzzer sounds
intermittently.
If the watercraft continues to be operated
at higher speeds after the warning system
has been activated, the warning light,
engine overheat warning indicator and the
buzzer will change from intermittently to
continuously on. (See “Engine overheat
warning system” on page 2-12 for further
details.)
The warning signals will turn off when the
engine is started after it has cooled down.
NOTE:@ When the warnings overlap each other, their
priority is as follows:
1. Final overheat warning
2. Fuel level warning
3. Oil level warning
4. Initial overheat warning
5. Exhaust temperature warning
6. Check engine warning

Fuel and oil
This engine uses Yamaha’s oil injection
system, which provides superior lubrication
by ensuring the proper oil ratio for all operat-
ing conditions. No fuel premixing is neces-
sary except during the engine break-in
period. Simply pour gasoline into the fuel
tank and oil into the oil tank.
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.
EJU19122
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.

Filling the oil tank
WARNING@ Do not add gasoline to the oil tank.
Fire or explosion could result.
Oil in the bilge is a serious fire hazard.
Wipe up any spilled oil immediately.
@
CAUTION:@ Do not allow the oil tank to become com-
pletely empty. If the oil tank becomes
empty the oil injection pump must be
bled to ensure proper oil flow, otherwise
engine damage may occur. If bleeding of
the oil pump is necessary, have a
Yamaha dealer bleed it.
@
1. Remove the seat to watch the oil level.
(See page 2-5 for seat.)
2. Open the oil tank filler cap, and very
slowly add engine oil to the oil tank.
3. Stop filling when the oil just reaches the
top of oil tank visible.
Oil tank capacity:
5.5 L (1.5 US gal, 1.2 Imp gal)
