Hazard information

Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monoxide,
a colorless, odorless gas that may cause
loss of consciousness and death within a
short time. Always operate the watercraft
in an open area.

Do not start engine on land until everyone
is away from stern. Hot water and steam
spurting from exhaust outlet can cause
serious burns.

Hot muffler surfaces can cause serious
burns. Do not touch any muffler surface
during or after engine operation. Catalytic
converter gets hotter after engine stops.

Watercraft characteristics

Jet thrust turns the watercraft. Releasing
the throttle lever completely produces
only minimum thrust. If you are traveling
at speeds above trolling, you will have
rapidly decreasing ability to steer without
throttle. This model has the Yamaha
Engine Management System (YEMS)
that includes an Off-Throttle Steering
(OTS) system. It will activate at planing
speeds should you attempt to steer the
watercraft after releasing the throttle lever.
The OTS system assists in turning by
continuing to supply some thrust while the
watercraft is decelerating, but you can
turn more sharply if you apply throttle
while turning the handlebars. The OTS
system does not function below planing
speeds or when the engine is off. Once
the engine slows down, the watercraft will
no longer turn in response to handlebar
input until you apply throttle again or you
reach trolling speed. Practice turning in
an open area without obstructions until
you have a good feel for this maneuver.

This watercraft is water-jet propelled. The
jet pump is directly connected to the
engine. This means that jet thrust will pro-
duce some movement whenever the
engine is running. There is no “neutral”
position.

CAUTION:@ This model is equipped with a catalytic
converter.

When the exhaust temperature warn-
ing system is activated, reduce engine
speed (below 4,000 r/min) and beach
the watercraft.

If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate
at higher speeds could result in severe
engine damage.
@
NOTE:@ Press the select button on the multifunction
information center to stop the buzzer.

CAUTION:@
Do not run the engine over 4,000 r/min
to check the meter for operation on
land. The engine could overheat or the
catalytic converter could result in seri-
ous damage.

Use the specified resistor-type spark
plug and cap, otherwise the meter may
function erratically.
@
NOTE:@ All display light up and the buzzer sounds
twice after the engine starts. Then, the
meter will operate normally after few sec-
onds. The current display will continue to
operate for 25 seconds after the engine
stops.

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 tem-
porarily 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 filler cap securely after
refueling.

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
CAUTION:@
Do not use leaded gasoline. Leaded
gasoline can seriously damage the
catalytic converter.

Use only fresh gasoline that has been
stored in clean containers.
@
Recommended gasoline:
Regular unleaded gasoline with
a minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)

Post-operation checks
WARNING@ Stay away from stern when engine is run-
ning on land. Hot water and steam spurt-
ing from exhaust outlet into the air can
cause serious burns.
@
Always perform the following post-opera-
tion checks after operating the watercraft.
1. Remove the watercraft from the water.
2. Wash down the hull, handlebars, and jet
unit with fresh water.
3. Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow water in the bilge to
drain out.
NOTE:@ This watercraft is equipped with a jet vac-
uum bilge draining system and an electric
bilge draining system that remove water
from the engine compartment while you are
underway. However, some residual water will
remain. (See “Bilge” on page 3-9 for more
information.)
@
4. Put the watercraft in a horizontal posi-
tion.
5. Flush the cooling system to prevent it
from clogging with salt, sand, or dirt.
(See page 4-1 for flushing procedures.)
6. Drain residual water from the exhaust sys-
tem by running the engine at 4,000 r/min
for 10 to 15 seconds.
CAUTION:@ Do not run engine over 4,000 r/min on
land. Otherwise catalytic converter could
sustain serious damage.

7. If the watercraft will be stored for a week
or more, lubricate internal engine com-
ponents to help prevent corrosion. (See
page 4-3 for lubrication procedures.)
8. Rinse the engine and engine compart-
ment with a small amount of water.
CAUTION:@ Do not use high pressure when rinsing
the engine or engine compartment as
severe engine damage could result.
@
9. Wipe the engine and engine compart-
ment dry with a clean cloth (repeat
step 3, if necessary).
10. Wipe the hull, handlebars, and jet unit
dry with a clean cloth.
11. Spray a rust inhibitor on metallic parts to
minimize corrosion.
WARNING@ Do not spray flammable rust inhibitor
products on engine surfaces while the
engine is hot. The sprayed substance or
propellants could catch fire.
@
12. Allow the engine compartment to air dry
completely before installing the seat.
NOTE:@ Cover watercraft after engine and catalytic
converter cool down.

Storage
WARNING@ Always place the watercraft upright in a
horizontal position when storing it, oth-
erwise fuel could leak out into the engine
or engine compartment, which could
result in a fire hazard.
@
Storage for prolonged periods of time,
such as winter storage, requires preventa-
tive maintenance to ensure against deterio-
ration. It is advisable to have the watercraft
serviced by a Yamaha dealer prior to stor-
age. However, the following procedures can
be performed by the owner.
EJU11941
Flushing the cooling system
Flushing the cooling system is essential
to prevent the cooling system from being
clogged with salt, sand, or dirt.
WARNING@ Stay away from stern when engine is run-
ning on land. Hot water and steam spurt-
ing from exhaust outlet into the air can
cause serious burns.
@
CAUTION:@
Do not supply water to the cooling
water passages when the engine is not
running. The water could flow back
through the muffler into the crankcase
causing severe engine damage.

Do not run the engine of the watercraft
for more than 15 seconds without sup-
plying water, otherwise the engine may
overheat.

Do not run engine over 4,000 r/min on
land. The catalytic converter could
sustain serious damage.
