Enjoy your watercraft
responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility to
treat these other people, and the lands, wa-
ters, and wildlife with respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you. Re-
member, for example, that the sound of your
watercraft may be music to you, but it could be
just noise to others. And the exciting splash of
your wake can make waves others won’t en-
joy.
Avoid riding close to shoreline homes and wa-
terfowl nesting areas or other wildlife areas,
and keep a respectful distance from fisher-
men, other boats, swimmers, and populated
beaches. When travel in areas like these is
unavoidable, ride slowly and obey all laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within regu-
lated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, pollution can be harmful to the
environment. Do not refuel or add oil where a
spill could cause damage to nature. Remove
your watercraft from the water and move it
away from the shoreline before refueling. Dis-
pose of water and any fuel and oil residue in
the engine compartment according to local
regulations. And keep your surroundings
pleasant for the people and wildlife that share
the waterways: don’t litter.
When you ride responsibly, with respect and
courtesy for others, you help ensure that ourwaterways stay open for the enjoyment of a
variety of recreational opportunities.

WARNING
EWJ00282

Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.

Gasoline is poisonous and can cause in-
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
NOTICE
ECJ00321

Do not use leaded gasoline. Leaded gas-
oline can seriously damage the engine.

Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the
fuel meets the minimum octane ratings. E-85
is a fuel blend containing 85% ethanol and
therefore must not be used in this watercraft.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or en-
gine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.
EJU318722-stroke engine oil
If YAMALUBE 2-W engine oil is not available,
another 2-stroke engine oil with an NMMA-
certified TC-W3 rating may be used.
EJU31902Mixing fuel and oil
NOTICE
ECJ00331
Make sure that the gasoline and oil are
thoroughly mixed in the correct ratio, oth-
erwise severe engine damage could re-
sult.
To mix gasoline and engine oil:
(1) Pour 2-stroke engine oil into a clean con-
tainer, and then add gasoline.
Recommended fuel:
Regular unleaded gasoline with a mini-
mum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)
Recommended engine oil:
YAMALUBE 2-W or TC-W3 outboard
motor oil or equivalent
Fuel-to-oil ratios (gasoline to oil)
Break-in period (first two tankfuls):
25:1
After break-in:
50 :1

(2) To mix them thoroughly, shake the con-
tainer from side to side.
EJU31915Filling the fuel tank
To fill the fuel tank:
(1) Before refueling, stop the engine. Do not
stand or sit on the watercraft. Never refu-
el while smoking, or while in the vicinity of
sparks, open flames, or other sources of
ignition.
(2) Place the watercraft in a well-ventilated
area and in a horizontal position.
(3) Remove the hood, and then check the
fuel level. (See page 22 for hood removal
and installation procedures.)
(4) Loosen the fuel filler cap and remove it.
(5) Slowly add fuel to the fuel tank.(6) Stop filling when the fuel level just reach-
es the bottom of the filler tube. Do not fill
up the filler tube. Because fuel expands
when it heats up, heat from the engine or
the sun can cause fuel to spill out of the
fuel tank. Do not leave the watercraft with
a full tank in direct sunlight.
(7) Wipe up any spilled fuel immediately with
a dry cloth.
(8) Install the fuel filler cap and tighten it se-
curely.
(9) Install the hood in its original position.

Engine break-in
NOTICE
ECJ00431
Failure to perform the engine break-in
could result in reduced engine life or even
severe engine damage.
The engine break-in is essential to allow the
various components of the engine to wear
and polish themselves to the correct operat-
ing clearances. This ensures proper perfor-
mance and promotes longer component life.
To perform the engine break-in:
(1) Fill the fuel tank with fuel in a fuel-to-oil ra-
tio of 25:1. (See page 26 “Mixing fuel and
oil” and “Filling the fuel tank” for fuel filling
procedures.)
(2) Launch the watercraft and start the en-
gine. (See page 40 for engine starting
procedures.)
(3) For the first 5 minutes, operate with the
engine at idling speed.
(4) For the first tankful of fuel, squeeze the
throttle lever slowly and operate at 3/4
throttle or less.
(5) Fill the fuel tank once more with fuel in a
fuel-to-oil ratio of 25:1, and then operate
with the engine at any speed.
After completing the engine break-in, fill the
fuel tank with fuel in a fuel-to-oil ratio of 50:1
and proceed with normal operation.

flows out continually from the cooling wa-
ter pilot outlet.
(7) Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn the
water supply off immediately and perform
the procedure again from step 6.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00122]
(8) Turn the water supply off.
(9) Discharge the remaining water out of the
cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(10) Stop the engine.
(11) Remove the garden hose adapter, and
then install the flushing hose connector
cap and tighten it securely.
(12) Install the hood in its original position.
EJU40741Cleaning the watercraft
(1) Remove the hood. (See page 22 for hood
removal and installation procedures.)
(2) Rinse the engine and engine compart-
ment with a small amount of water.
NOTICE: Do not use high-pressure
water when rinsing the engine or en-gine compartment as severe engine
damage could result.
[ECJ00571]
(3) Wipe the engine and engine compart-
ment with a dry cloth.
(4) Wash down the hull and jet pump with
fresh water.
(5) Wipe the hull and jet pump with a dry
cloth.
(6) Wipe all vinyl and rubber components,
such as the engine compartment seals,
with a vinyl protectant.
(7) To minimize corrosion, spray metallic
parts of the hull with a rust inhibitor.
(8) Allow the engine compartment to air dry
completely before installing the hood.
(9) Install the hood in its original position.
EJU33685Battery care
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft, check it, and then store it in a cool, dry
place.
WARNING
EWJ00791
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes, or clothing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten
egg, or vegetable oil. Call a physician im-
mediately.
Eyes: Flush with water for 15 minutes and
get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flames, cigarettes, etc., well away.
If using or charging the battery in an en-
closed space, make sure that it is well ven-
tilated. Always shield your eyes when
working near batteries.
