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:@ This model is equipped with a catalytic
converter.

When the exhaust temperature warn-
ing system is activated, reduce engine
speed (below 4,000 r/min) and beach
the watercraft.

If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate
at higher speeds could result in severe
engine damage.

NOTE:@ Press the select button on the multifunction
information center to stop the buzzer.

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.

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.

Lubrication
WARNING@ Do not spray flammable rust inhibitor
products on engine surfaces while the
engine is hot. The sprayed substance or
propellants could catch fire.
@
1. Remove the spark plugs and pour
approximately one tablespoon of oil into
each cylinder.
2. Grease the spark plug threads and rein-
stall the spark plugs.
3. Crank the engine within 3 seconds using
the start switch.
4. Lubricate all cables such as the throttle
and steering cables.
NOTE:@ Use a suitable marine grease applicator to
pressure lubricate the cables and purge out
any moisture between the inner and outer
cables.
@
5. Lubricate the areas of the watercraft
specified under Lubrication points on
page 4-15.
