If the overheat warning is ignored, engine
heat may increase, particularly if the water-
craft is operated at higher speeds. When
this occurs, the warning light and engine
overheat warning indicator begin to blink
rapidly, the buzzer sounds continuously, 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.)
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 the reset button on the multifunction
information center to stop the buzzer.

Handgrip
The handgrip 1 provides a handhold for
boarding the watercraft.
CAUTION:
Do not use to tow objects, lift watercraft,
or attach tie downs, otherwise damage
could occur.

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.
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. 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 just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow.
●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.
