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 color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.
Do not touch the hot muffler or engine dur-
ing or immediately after engine operation;
they can cause serious burns.
EJU30921
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 is equipped with the Yamaha
Engine Management System (YEMS) that
includes an off-throttle steering (OTS) sys-
tem. 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 sharp-
ly if you apply throttle while turning the han-
dlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the water-
craft will no longer turn in response to han-
dlebar input until you apply throttle again or
you reach trolling speed.
Practice turning in an open area without
obstacles until you have a good feel for this
maneuver.
This watercraft is water-jet propelled. The
jet pump is directly connected to the en-
gine. This means that jet thrust will produce
some movement whenever the engine is
running. There is no “neutral” position. You
are in either “forward” or “reverse”, de-
pending upon the shift lever position.
Do not use the reverse function to slow
d o w n o r s t o p t h e w a t e r c r a f t a s i t c o u l d c a u -
se you to lose control, be ejected, or im-
pact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and broken
legs, ankles, and other bones. You could
also damage the shift mechanism.

WARNING
EWJ00283
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
ECJ01870
Do not use leaded gasoline. Leaded
gasoline can seriously damage the en-
gine.
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.
Use only gasoline with a minimum pump
octane number of 91 or a minimum re-
search octane number of 95. Low-oc-
tane gasoline can seriously damage the
engine.
Your Yamaha engine has been designed to
use premium unleaded gasoline with a pump
octane number [(R+M)/2] of 91 or higher, or a
research octane number of 95 or higher. Ifknocking (or pinging) occurs, use a gasoline
of a different brand.
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
the fuel meets the minimum octane ratings.
E-85 is a fuel blend containing 85% ethanol
and therefore must not be used in this water-
craft. All ethanol blends containing more than
10% ethanol can cause fuel system damage
or engine 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, stop the engine. Do not
stand or sit on the watercraft. Never refu-
el while smoking, or while in the vicinity
of sparks, open flames, or other sources
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 40 for seat removal
and installation procedures.) Recommended fuel:
Premium unleaded gasoline with a
minimum octane rating of
91
(Pump octane number) = (R + M)/2
95 (Research octane number)

maining moisture in the engine compart-
ment with a dry cloth.
(4) Securely install the stern drain plugs by
tightening them until they stop. NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads and the
O-rings on the plugs to remove any
foreign materials, such as dirt or sand.
Otherwise, the stern drain plugs could
be damaged, allowing water to enter
the engine compartment. Check the
O-rings on the stern drain plugs and
make sure that the plugs are tightened
securely before launching the water-
craft. Otherwise, water may flood the
engine compartment and cause the
watercraft to submerge.

EJU40044
Draining the bilge water on water
A small quantity of bilge water will remain in
the engine compartment even after the bilge
water is drained on water. To completely
drain the bilge water, remove the watercraft
from the water and drain the bilge water on
land.
Jet vacuum bilge draining system
While the watercraft is operating, bilge water
in the engine compartment is drawn in by the
vacuum that is generated in the jet pump and
discharged from the watercraft through the
jet thrust nozzle.
To drain the bilge water on water:
Operate the watercraft as straight as possible
and above planing speed for at least 2 minu-
tes. NOTICE: Do not run the engine at full
throttle for at least 1 minute after the en-
gine has been restarted. Bilge water in the
engine compartment can splash into theengine, which can result in severe dam-
age.
[ECJ00554]
Electric bilge draining system
Bilge water in the engine compartment is
drawn in by the operation of the electric bilge
pump and discharged from the watercraft.
To check for proper operation of the electric
bilge draining system, make sure that bilge
water is being discharged from the electric
bilge pilot outlet.
To drain the bilge water:
Start the engine to operate the electric bilge
pump.
TIP:
The electric bilge pump continues to operate
for a short time after the engine stops.

EJU33255Turning the watercraft
WARNING
EWJ00772
Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.
When operating at higher speeds, make
gradual turns or slow down before turn-
ing. Sharp high-speed turns may cause
the watercraft to slide sideways or spin,
throwing the operator and passenger(s)
overboard, which could cause an injury.
Steering control depends on the combination
of handlebar position and the amount of
throttle.Water sucked in through the intake grate is
pressurized by the impeller in the jet pump.
As the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.
B. Less throttle produces lower thrust, so
the watercraft will turn more gradually.
C. 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. You may still have
some turning ability immediately after re-
leasing the throttle lever, but once the

Post-operation care
WARNING
EWJ00331
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create
a fire hazard.
After using the watercraft, always take it out
of the water, clean it, and store it. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deteriora-
tion of the jet pump and hull. Marine organ-
isms and corrosion are some of the
conditions that can shorten the life of many
watercraft components.
EJU37564Flushing the cooling water passages
NOTICE
ECJ01880
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for
more than 15 seconds without supplying
water, otherwise the engine could over-
heat.
Flush the cooling water passages to
prevent them from clogging with salt,
sand, or dirt.
(1) Place the watercraft in a horizontal posi-
tion.
(2) Remove the seats and watertight stor-
age compartment. (See page 40 for seat
removal and installation procedures and
page 45 for information on the watertight
storage compartment.)(3) Connect the garden hose adapter to a
garden hose.
(4) Loosen the flushing hose connector cap
and remove it. Insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.
(5) Connect the garden hose to a water tap.
(6) Make sure that the area around the wa-
tercraft is clear, and then start the en-
gine. Immediately after the engine starts,
fully turn the water supply on so that wa-

thrust nozzle.
(7) Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
perform the procedure again from step 6.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00123]
(8) Turn the water supply off.
(9) Discharge the remaining water out of the
cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(10) Stop the engine.
(11) Remove the garden hose adapter, and
then securely install the flushing hose
connector cap by tightening it until it
stops.
(12) Securely install the watertight storage
compartment and seats in their original
positions.
EJU33736Cleaning the watercraft
(1) Remove the seats. (See page 40 for seat
removal and installation procedures.)
(2) Rinse the engine and engine compart-
ment with a small amount of water.NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.
[ECJ00572]
(3) Drain the water from the engine com-
partment. (See page 50 for information
on draining the bilge water.)
(4) Wipe the engine and engine compart-
ment with a dry cloth.
(5) Wash down the hull, deck, and jet pump
with fresh water.
(6) Wipe the hull, deck, and jet pump with a
dry cloth.
(7) Wipe all vinyl and rubber components,
such as the seats and engine compart-
ment seals, with a vinyl protectant.
(8) To minimize corrosion, spray metallic
parts of the hull, deck, and engine with a
rust inhibitor.
(9) Allow the engine compartment to air dry
completely before installing the seats.
(10) Securely install the seats in their original
positions.
