WARNING
EWJ00290
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!
● Do not smoke when refueling, and keep
away from sparks, flames, and other
sources of ignition.
● Stop the 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 tempo-
rarily leaving the watercraft with a full
fuel tank, do not leave it in direct sun-
light. Leave it in a well-ventilated area
with the watercraft in a horizontal posi-
tion.
● Tighten the fuel tank filler cap securely
after refueling.
● If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso-
line in your eyes, get immediate medical
attention.
● If any gasoline spills on your skin or
clothing, immediately wash the affected
area with soap and water and change
your clothes.

taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the

Gasohol containing methanol is not recom-
mended by Yamaha because it can cause
fuel system damage and engine performance
problems.
