If this occurs, reduce the engine speed, return
to shore, and then check the engine oil level.
(See page 42 for engine oil level checking
procedures.) If the oil level is low, add enough
engine oil to raise it to the proper level. If the
oil level is sufficient, have a Yamaha dealer
check the watercraft.

ING” light and the engine overheat warning in-
dicator blink, and then come on. The buzzer
also begins to sound intermittently, and then it
sounds continuously. After the light and indi-
cator start to blink and the buzzer sounds, theengine speed is limited to help prevent dam-
age.
If this occurs, immediately reduce the engine
speed, return to shore, and then check for wa-
ter discharge at the port (left) cooling water pi-
lot outlet while the engine is running. If there
is no discharge of water, shut the engine off,
and then check the intake grate and impeller
for clogging.
WARNING
EWJ00050
Before attempting to remove weeds or de-
bris from the intake grate or impeller, shut
the engine off and remove the clip from the
engine shut-off switch. Severe injury or

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)

EJU32900
Operating your watercraft EJU32960Getting to know your watercraft
Operating your watercraft requires skills ac-
quired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneu-
vers.
Operating your new watercraft can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar-
ize yourself with the operation of the water-
craft to achieve the skill level necessary to
enjoy riding safely.
Before operating this watercraft, read this
owner’s/operator’s manual, the Riding Prac-
tice Guide, and all warning and caution labels
on the watercraft. Pay particular attention to
the safety information on page 9. These ma-
terials should give you an understanding of
the watercraft and its operation.
Remember: This watercraft is designed to
carry the operator and up to 2 passengers.
Never exceed the maximum load limit or allow
more than 3 persons (or 2 persons if a water-
skier is being pulled) to ride the watercraft at
any time.
EJU33000Learning to operate your watercraft
Before operating the watercraft, always per-
form the pre-operation checks listed on page
40. The short time spent checking the water-
craft will reward you with added safety and re-
liability.
Check local laws before operating your water-
craft.Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other watercraft. Select a wide area to
learn in, where there is good visibility and light
boat traffic.
Use the buddy system—operate with some-
one nearby. Scan constantly for people, ob-
jects, and other watercraft. Be alert for
conditions that limit your visibility or block your
vision of others.
Attach the engine shut-off cord to your left
wrist and keep it free from the handlebars so
that the engine stops if you, the operator, fall
off.
Wear a personal flotation device (PFD). All
riders must wear a PFD that is approved by
the appropriate authorities and is suitable for
personal watercraft use.
Wear protective clothing. Severe internal inju-
ries can occur if water is forced into body cav-
ities as a result of falling into the water or
being near the jet thrust nozzle. Normal swim-
wear does not adequately protect against
forceful water entry into the rectum and vagi-
na. All riders must wear a wetsuit bottom or
clothing that provides equivalent protection.
Such clothing includes thick, tightly woven,
sturdy and snug-fitting apparel such as den-
im, but does not include spandex or similar
fabrics, like those used in bicycle shorts. A full
wetsuit can also protect against hypothermia Maximum load:
240 kg (530 lb)
Load is the total weight of cargo, oper-
ator, and passengers.
