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. And
keep your surroundings pleasant for the peo-
ple and wildlife that share the waterways:
don’t litter!
When you ride responsibly, with respect and
courtesy for others, you help ensure that our
waterways stay open for the enjoyment of a
variety of recreational opportunities.

Fuel and oil
This watercraft is equipped with a 4-stroke en-
gine. Conventional 2-stroke engine oil cannot
be used.
The engine utilizes an electronic fuel injection
system to deliver the optimal air-fuel ratio re-
quired by the engine. By ensuring the optimal
combustion conditions, this system is able to
increase startability and improve fuel econo-
my.
EJU31841Gasoline
WARNING
EWJ00280
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 reaches approxi-
mately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily 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 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.
CAUTION:
ECJ00310
Use only fresh gasoline that has been
stored in clean containers.
EJU31860Gasohol
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.
Gasohol containing methanol is not recom-
mended by Yamaha because it can cause
fuel system damage and engine performance
problems.Recommended gasoline:
Regular unleaded gasoline with a mini-
mum octane rating of
86 (Pump octane number) = (R +
M)/2
90 (Research octane number)

EJU32400Engine oil level
Check the engine oil level before each use.
CAUTION:
ECJ00390

When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and wind can cause the
watercraft to move and lead to a colli-
sion.

When checking the engine oil level on
land, supply water to the cooling water
passages. (See page 63 for procedures
on supplying water.)

Make sure that the engine has enough
oil, but do not overfill it. If there is too lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter can be-
come saturated with oil, permanently
damaging the filter and reducing engine
performance. Follow the checking pro-
cedure carefully.

Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
To check the engine oil level:
(1) Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.
