EJU35930Steering system
Your watercraft can be steered by turning the
handlebars in the direction you wish to travel.
When the handlebars are turned, the angle of
the jet thrust nozzle is changed, and the direc-
tion of the watercraft is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn, ex-
cept at trolling speed.
The angle of the jet thrust nozzle can be ad-
justed to suit operator preference. (See page
53 for adjustment procedures.)
EJU31270Steering pole
The steering pole varies in height with the op-
erator’s posture, enabling the operator to as-
sume various riding positions.
When removing the hood for pre-operation
checks, maintenance, etc., lift the steering
pole and use the lock pin to support it. Move
the lock pin into the detent. Make sure that the
lock pin is returned to the stowed position af-
ter installing the hood.
EJU36000Bow rope hole
The bow rope hole is located at the bow of the
watercraft.

to-oil ratio could result in fouled spark
plugs, smoky exhaust, and heavy car-
bon deposits.
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.
EJU31910Filling the fuel tank
CAUTION:
ECJ00290
Be careful when refueling. Avoid getting
water and other contaminants in the fuel
tank. Contaminated fuel can cause poor
running and engine damage.
(1) Lift the steering pole and support it with
the lock pin.
(2) Remove the hood. (See page 18 for hood
removal and installation procedures.)
(3) Remove the fuel tank filler cap, and then
slowly add the premixed fuel to the fueltank. Stop filling when the fuel level just
reaches the bottom of the filler tube.
(4) Install the fuel tank filler cap and the
hood.
NOTE:
The hood must be removed in order to view
the fuel level in the fuel tank while adding fu-
el.
Be careful not to spill fuel or overfill the fuel
tank.
Do not fill up the filler tube because fuel ex-
pands as it warms up and could overflow.

Pre-operation checks EJU31990Pre-operation check list
Before operating this watercraft, perform the checks in the following check list. See the accom-
panying text in this chapter for details on how to perform the checks.
WARNING
EWJ00410
If any item in the pre-operation check list is not working properly, have it inspected and
repaired before operating the watercraft, otherwise an accident could occur.
NOTE:
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.
ITEM ROUTINE PAGE

ment. Check for fuel vapors and loose electrical con-
nections.28

EJU32280Pre-operation check points EJU32290Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, lift the
steering pole and support it with the lock pin,
and then remove the hood. (See page 18 for
hood removal and installation procedures.)
Leave the engine compartment open for a few
minutes to allow any fuel vapors to escape.
While the engine compartment is open, check
for loose electrical connections.
WARNING
EWJ00460
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak or
a loose electrical connection.
EJU32350Hull and deck
Check the hull and deck for cracks and other
damage. If any damage is found, have a
Yamaha dealer repair the watercraft.
EJU32360Fuel system
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
52 for check points and correct procedures.)(1) Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
(2) Remove the hood. (See page 18 for hood
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 26 for
filling procedures.)
(4) Install the fuel tank filler cap and the
hood.
EJU32420Water separator
Check the water separator for water. The wa-
ter separator retains any water that may have
entered through the fuel tank breather hose if
the watercraft was capsized. Normally, the
water separator is empty.
If water remains in the water separator, drain
it by removing the drain screw. Place a drain
pan under the water separator to catch the

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.
EJU32430Bilge
Check the bilge for moisture and fuel residue.
CAUTION:
ECJ00340
Excessive water in the bilge can splash
into the carburetor and engine, which can
result in severe damage.
EJU32480Battery
Check the battery condition and the electro-
lyte level.
Check that the battery leads are tightened se-
curely and that there is no corrosion on the
battery terminals.
WARNING
EWJ00450
The battery must always be fully
charged and in good condition. Loss of
battery power may leave you stranded.
Never operate the watercraft if the bat-
tery does not have sufficient power tostart the engine or if it shows any other
signs of decreased power.
Be sure to connect the breather hose to
the battery. Fire or explosion could re-
sult if the breather hose is damaged, ob-
structed, or not connected properly.
Make sure that the battery is securely held in
place.
EJU32500Fire 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.

CAUTION:
ECJ00400
Do not force the fire extinguisher contain-
er up more than 30 degrees from the stor-
age position, otherwise the container and
hood could be damaged.
(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.
NOTE:
To check the fire extinguisher, see the in-
structions supplied by the fire extinguisher
manufacturer. Always keep the fire extin-
guisher in the fire extinguisher container.
Always carry a fire extinguisher on board. A
fire extinguisher is not standard equipment
with this watercraft. If you do not have one,
contact a Yamaha dealer or a fire extin-
guisher dealer to obtain one meeting the
proper specifications.
EJU32590Throttle 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.
WARNING
EWJ00490
Before starting the engine, always check
the operation of the throttle lever.
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
turned, and that there is no free play between
the handlebars and the jet thrust nozzle.
EJU32620Steering pole
Check the steering pole for looseness.
