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

Exhaust temperature warning
indicator
If the exhaust system becomes too hot,
the warning light and exhaust temperature
warning indicator begin to blink, and the
buzzer sounds intermittently. (See “Exhaust
temperature warning system” on page 2-13

A front storage compartment and a glove
compartment are provided.
NOTE:@ Make sure that the storage compartments
are properly secured before operating the
watercraft.
The storage compartments are not
designed to be waterproof. If you carry
objects that must be kept dry, such as the
manuals, put them in a waterproof bag.

Front storage compartment
The front storage compartment 2 is
located at the bow.
To open the front storage compartment,
push the hood latch 1 down, and then open
the hood.
NOTE:@ The front storage compartment can be
removed to access the engine compart-
ment.

Yamaha Adjustable Sponson
(YAS)
The sponsons 1 have adjustable posi-
tioning to allow the operator to enhance
either straight-line performance or turning
performance according to the preference
and operating conditions. (See page 4-22
for adjustment procedures.)
Up position A:
There will be less water resistance in this
position, so straight-ahead acceleration
when on plane and top speed will be
enhanced.
Down position B:
This position will give the watercraft more
“hook” which will enhance turning perfor-
mance.

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.
