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.
If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
CAUTION:@ Use only fresh gasoline that has been
stored in clean containers.

Gasohol
There are two types of gasohol: gasohol
containing ethanol and that containing meth-
anol.
Gasohol containing ethanol can be used
if ethanol content does not exceed 10% and
the fuel meets minimum octane ratings.
Gasohol containing methanol is not rec-
ommended by Yamaha because it can
cause fuel system damage or engine perfor-
mance problems.
EJU10441
2-stroke engine oil
If YAMALUBE 2-W oil is not available,
another 2-stroke engine oil with an
NMMA-certified TC-W3 rating may be used. Recommended gasoline:
Regular unleaded gasoline with a
minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)
Recommended engine oil:
YAMALUBE 2-W oil

Mixing fuel and oil
CAUTION:@ Avoid using any mixture of gasoline
and oil other than those designated.
Make sure gasoline and oil are thor-
oughly mixed in the correct ratio, oth-
erwise the following problems may
occur. Too little oil in the fuel mixing
ratio could result in major engine trou-
ble, such as seizure. Too much oil in
the fuel mixing ratio could result in
fouled spark plugs, smoky exhaust, or
heavy carbon deposits.
@
Pour 2-stroke engine oil 1 into a clean
container, and then add gasoline 2. To mix
them thoroughly, shake the container from
side to side.
Fuel mixing ratios (gasoline to oil)
Break-in period
(first two tankfuls): 25 : 1
After break-in: 50 : 1

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. Lift the steering pole and support it with
the lock pin.
2. Remove the hood.
3. Open the fuel tank filler cap, and slowly
add the premixed fuel to the fuel tank.
4. Stop filling when the fuel level just
reaches the bottom of the filler tube.
NOTE:@ The hood must be removed in order to
watch the fuel level in the fuel tank while
adding fuel.
Be careful not to spill fuel or overfill the
tank.
Do not fill into the filler tube because fuel
could overflow.
@
Fuel tank capacity:
Total: 18 L (4.8 US gal, 4.0 Imp gal)
Reserve: 5.5 L
(1.45 US gal, 1.21 Imp gal)
