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.
EJU01911
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 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. If tem-
porarily leaving the watercraft with a
full fuel tank, do not leave it in direct
sunlight. Leave it in a well-ventilated
area with the watercraft in a horizontal
position.

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.
