Oil pressure warning indicator
If the oil pressure does not rise to specifi-
cation, the “WARNING” indicator light and
the oil pressure warning indicator begin to
blink and the buzzer sounds intermittently.
At the same time, the engine speed is lim-
ited to help prevent damage.
If this occurs, reduce the engine speed,
return to shore, and then check the engine
oil level. (See page 3-7 for engine oil level
checking procedures.) If the oil level is low,
add enough engine oil to raise it to the
proper level. If the oil level is sufficient, have
a Yamaha dealer check the watercraft.
NOTE:@ Press any button on the multifunction meter
to stop the buzzer.

Engine overheat warning indicator
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the
“WARNING” indicator light and the overheat
warning indicator blink, and then come on.
The buzzer also begins to sound intermit-
tently, and then it sounds continuously. After
the light and indicator start to blink and the
buzzer sounds, the engine speed is limited
to help prevent damage.
If this occurs, immediately reduce the
engine speed, return to shore, and then
check for water discharge at the port (left)
cooling water pilot outlet. If there is no dis-
charge of water, check the intake grate and
impeller for clogging.
WARNING@ Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
@
CAUTION:@ 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 any button on the multifunction meter
to stop the buzzer.

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.
