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.

speeds. If this occurs, the “WARNING” light
and the engine overheat warning indicator
come on and the buzzer sounds continuously.
In addition, the warning system will cut the ig-
nition to the engine to reduce the risk of se-
vere overheating. The engine cannot be
started until it cools down, so it may be neces-
sary to have the watercraft towed back to the
shore. (See “Towing the watercraft” on page
78 for towing procedures.)
The warning signals will be cleared when the
engine is restarted after it has cooled down.
NOTE:
If multiple warnings occur at the same time,
their priority is as follows:
(1) Final engine overheat warning
(2) Fuel level warning
(3) Oil level warning
(4) Initial engine overheat warning
(5) Exhaust temperature warning
(6) Check engine warning

Fuel and oil
This engine uses Yamaha’s oil injection sys-
tem, which provides superior lubrication by
ensuring the proper fuel-to-oil ratio for all op-
erating conditions. No fuel premixing is nec-
essary, except during the engine break-in
period. Simply pour gasoline into the fuel tank
and oil into the oil tank.
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.
EJU31850Gasoline
WARNING
EWJ00440
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 areawith 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.
CAUTION:
ECJ00320
Do not use leaded gasoline. Leaded gas-
oline can seriously damage the catalytic
converter.
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)
