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 thefuel 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.
To fill the fuel tank:
(1) Before refueling, turn off the engine. Do
not stand or sit on the watercraft. Never
refuel while smoking, or while in the vicin-
ity of sparks, open flames, or other sourc-
es of ignition.
(2) Place the watercraft in a well-ventilated
area and in a horizontal position.
(3) Remove the seats, and then check the
fuel level. (See page 25 for seat removal
and installation procedures.)
(4) Open the hood. (See page 26 for hood
opening and closing procedures.)
(5) Remove the fuel tank filler cap, and then
slowly add fuel to the fuel tank. Stop filling
when the fuel level reaches approximate-
ly 50 mm (2 in) from the top of the fuel
tank. Do not overfill the fuel tank. Be-
cause 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. Recommended fuel:
Regular unleaded gasoline with a mini-
mum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)

Operating your watercraft EJU32961Getting 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, the Riding Instruction card, and all
labels on the watercraft. Pay particular atten-
tion to the safety information on page 10.
These materials should give you an under-
standing 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.
EJU33001Learning to operate your watercraft
Before operating the watercraft, always per-
form the pre-operation checks listed on page
50. 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 (lanyard) to
your left wrist and keep it free from the handle-
bars so that the engine stops if you, the oper-
ator, 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.
