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.
EJU01042
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.

Filling the fuel tank
CAUTION:@ Be careful when refueling. Avoid getting
water or other contaminants in the fuel
tank. Contaminated fuel can cause poor
running or engine damage.
@
1. Open the hood and remove the front
storage compartment. Also, remove all
seats, so you can watch the fuel level.
(See page 2-6 for hood, and pages 2-4
and 2-5 for seats.)
2. Open the fuel tank filler cap, and slowly
add fuel to the fuel tank.
3. Stop filling when the fuel just reaches the
bottom of the filler tube on the fuel tank.
Do not fill into the filler tube, because
fuel could spill out.
Fuel tank capacity:
Total: 50 L (13.2 US gal, 11 Imp gal)
Reserve: 12 L (3.17 US gal, 2.64 Imp gal)

Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment,
remove all seats and front storage compart-
ment. (See pages 2-4 and 2-5 for front and
rear seat, and 2-14 for front storage com-
partment.) Allow the engine compartment to
remain open for a few minutes to allow any
fuel vapors to escape. Also, check for loose
electrical connections.
WARNING@ Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or a loose electrical connection.
@
EJU01242
Fuel and oil systems
Check the fuel system for leakage, cracks
or malfunctions before each use. (See page
4-9 for check points and correct proce-
dures.)
1. Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
2. Remove all seats and front storage com-
partment. (See pages 2-4 and 2-5 for
front and rear seat, and 2-14 for front
storage compartment.)
3. Check the fuel and oil levels in the tanks
and replenish if necessary. (See pages
3-3 and 3-4 for filling instructions.)
