dures.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-
ate at higher speeds could result in severe
engine damage.

Storage pouch
A storage pouch is provided on the underside
of the hood for the owner’s/operator’s manual,
tool kit, and other small items.
Bend the owner’s/operator’s manual slightly
to insert it into the storage pouch, and then
add the tool kit and any other small items.
Fold the pouch, and then wrap the strap
around it. Install the storage pouch on the

Pour 2-stroke engine oil into a clean contain-
er, and then add gasoline. To mix them thor-
oughly, shake the container from side to side.
EJU31912Filling the fuel tank
(1) Lift the steering pole and support it with
the lock pin.
(2) Remove the hood. (See page 17 for hood
removal and installation procedures.)
(3) Remove the fuel tank filler cap, and then
slowly add premixed fuel to the fuel tank.
Stop filling when the fuel level just reach-
es the bottom of the filler tube. Do not fill
up the filler tube. Because fuel expands
when it heats up, heat from the engine or
the sun can cause fuel to spill out of thefuel tank. Do not leave the watercraft with
a full tank in direct sunlight.
(4) Wipe up any spilled fuel immediately.
(5) Install the fuel tank filler cap and the
hood. Make sure that the fuel tank filler
cap is securely closed before operating
the watercraft.

Pre-operation checks EJU31991Pre-operation check list
Before operating this watercraft, perform the checks in the following check list.
WARNING
EWJ00411
Failure to inspect or maintain the watercraft properly increases the possibility of an ac-
cident or damage to the watercraft. Do not operate the watercraft if you find any prob-
lem. If a problem cannot be corrected by the procedures provided in this manual, have
the watercraft inspected by a Yamaha dealer.
TIP:
Pre-operation checks should be made each time the watercraft is used. These checks can be
completed in a short time. It is worth the time spent to ensure safety and reliability.

draining water or use a dry cloth to soak up
any water that could spill into the watercraft. If
any water spills into the watercraft, be sure to
wipe it up with a dry cloth. Also, be sure to in-
stall the drain screw after draining the water
separator.
EJU32432Bilge
Check the bilge. Wipe up any remaining mois-
ture or fuel residue with a dry rag. NOTICE:
Excessive water in the engine compart-
ment can splash into the engine, which
can result in severe damage.
[ECJ00341]
EJU32482
Battery
Check the battery electrolyte level and check
that the battery has sufficient power to start
the engine easily. WARNING! Never operate
the watercraft if the battery does not have
sufficient power to start the engine or if it
shows any other signs of decreased pow-
er. Loss of battery power may leave you
stranded.
[EWJ01240]
Recharge the battery or replace it if it is not in
good condition. (See page 57 for battery re-
charging procedures.)
Also, check that the battery leads are tight-
ened securely and that there is no corrosion
on the battery terminals. Check that the
breather hose is securely connected to the
battery and that it is not pinched. WARNING!
Fire or explosion could result if the breath-er hose is damaged, obstructed, or not
connected properly.
[EWJ00451]
Make sure that the battery is securely held in
place.
EJU32501Fire extinguisher
Check that there is a full fire extinguisher on
board.
The fire extinguisher container is located on
the hood under the steering pole.

To open the fire extinguisher container:
(1) Grasp the tab, pull the band to the rear,
and then pull it up.
(2) Lift the container about 30 degrees from
the storage position. NOTICE: Do not
force the fire extinguisher container
up more than 30 degrees from the
storage position, otherwise the con-
tainer and hood could be damaged.
[ECJ00401]
(3) Remove the cap to access the fire extin-
guisher.
To close the fire extinguisher container:
(1) Insert the fire extinguisher into the con-
tainer, and then install the cap and tighten
it securely.(2) Lower the container on the hood to its
storage position and secure it with the
band.
To check the fire extinguisher, see the in-
structions supplied by the fire extinguish-
er manufacturer. Always keep the fire
extinguisher in the fire extinguisher con-
tainer.
Always carry a fire extinguisher on board.
A fire extinguisher is not standard equip-
ment with this watercraft. If you do not
have one, contact a Yamaha dealer or a
fire extinguisher dealer to obtain one
meeting the proper specifications.
EJU32591Throttle lever
Check the throttle lever for proper operation.
Squeeze and release the throttle lever several
times to make sure that there is no hesitation
in its travel. It should be smooth over the com-
plete range and spring back to the idle posi-
tion when released.
EJU32600Steering system
Check the handlebars for looseness.
Turn the handlebars as far as possible to the
right and left to make sure that operation is
smooth and unrestricted throughout the
whole range. Also, make sure that the jet
thrust nozzle moves as the handlebars are

steer away from a boat or other obstacle
that comes into your path.
EJU33301Beaching the watercraft
(1) Make sure that there are no boats, swim-
mers, or obstacles near the beach. Re-
lease the throttle lever about 90 m (300 ft)
before you reach the intended beaching
area.
(2) Approach the beach slowly and stop the
engine before reaching land.
Remember, you need throttle to steer.
(3) Get off the watercraft and pull it up on the
beach. NOTICE: Small pebbles, sand,
seaweed, and other debris can be
sucked into the jet intake and impair
or damage the impeller. Always stop
the engine and get off the watercraft
before beaching it.
[ECJ00491]
EJU37190
Operating in weeded areas
Always avoid operating your watercraft in ar-
eas where weed growth is thick. If traveling in
weeded areas is unavoidable, operate the en-
gine alternately at partial throttle and full throt-
tle. Weeds tend to accumulate more at a
steady speed and at trolling speed. If weeds
clog the intake area and cause cavitation,
clean the jet intake and impeller. (See page
63 for cleaning procedures.)
EJU33362
Post-operation care
To keep your watercraft in top shape, always
take it out of the water after using it and per-
form the following procedures. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deterioration
of the jet unit components and hull finish. Ma-
rine organisms and corrosion are some of the
conditions that can adversely affect the life of
many watercraft components.
(1) Remove the watercraft from the water.
(2) Wash down the hull, steering pole, han-
dlebars, and jet unit with fresh water.
(3) Remove the hood and check the engine
compartment for water. To drain excess
water, turn the watercraft onto its port
(left) side. If necessary, turn the water-
craft upside down to drain the water com-
pletely. Place a suitable clean cloth or
carpeting underneath the watercraft to
protect it from abrasions and scratches.
NOTICE: Always turn the watercraft
over onto its port (left) side, otherwise
the water could flow back through the
muffler into the engine. When turning
the watercraft onto its side or invert-
ing it, support the bow and secure the
steering pole, otherwise the steering
pole and handlebars could be bent or
damaged.
[ECJ00581]
TIP:
This watercraft is equipped with an automatic
bilge draining system that removes water
from the engine compartment while you are
underway. However, some residual water will
remain, therefore, wipe it up with a clean
cloth.
(4) Place the watercraft in a horizontal posi-
tion.
