Hood
The hood is secured at the rear by a
latch.
Lift the steering pole and support it with
the lock pin before removing the hood.
To remove the hood:
1. Turn the latch knob 1 to the open posi-
tion, and then pull up on the hood latch 2
to unlatch the hood.
2. Grasp the hood using the handgrips 3
provided at the front and rear side of the
hood. Lift the hood up and to the rear to
remove it.
To install the hood:
1. Position the hood on the deck so the two

Cooling water pilot outlet
This watercraft is equipped with a cooling
water pilot outlet on the port (left) side of the
watercraft.
When the engine is running, cooling
water is circulated in the engine, and then it
is discharged from the pilot outlet. To check
for proper operation of the cooling system,
check that water is being discharged from
the pilot outlet. If water is not being dis-
charged from the outlet, cooling water may
not be circulating in the engine. When this
occurs, stop the engine and check for the
cause. (See pages 2-9 and 5-3 for further
instructions.)
NOTE:@If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlet after the engine is started.

EJU00356
Steering system
Your watercraft can be steered by turning
the handlebars 1 the same direction you
wish to travel. When the handlebars are
turned, the angle of the jet thrust nozzle 2
is changed, and the direction of the water-
craft is changes accordingly. Since the
strength of the jet thrust determines the
speed and direction of a turn, the throttle
must always be open when attempting a
turn, except at trolling speed.

Steering pole
The steering pole varies in height with the
operator’s posture, enabling the operator to
assume various riding positions.
When removing the hood for pre-opera-
tion checks, maintenance, etc., lift the steer-
ing pole 1 and use the lock pin 2 to
support it. Move the lock pin into the detent.
Make sure the lock pin is returned to the
stowed position after installing the hood.

Filling the fuel tank
CAUTION:@Be careful when refueling. Avoid getting
water or other contaminants in the fuel
tank. Contaminated fuel can cause poor
running or engine damage.
@
1. Lift the steering pole and support it with
the lock pin.
2. Remove the hood.
3. Open the fuel tank filler cap, and slowly
add the premixed fuel to the fuel tank.
4. Stop filling when the fuel level just
reaches the bottom of the filler tube.
NOTE:@●The hood must be removed in order to
watch the fuel level in the fuel tank while
adding fuel.
●Be careful not to spill fuel or overfill the
tank.
●Do not fill into the filler tube because fuel
could overflow.
@
Fuel tank capacity:
Total: 18 L (4.8 US gal, 4.0 Imp gal)
Reserve: 5.5 L (1.45 US gal, 1.21 Imp gal)

Pre-operation check points
Engine compartment
Ventilate the engine compartment, before
each use. To ventilate the engine compart-
ment, lift the steering pole and support it
with the stopper pin, then remove the hood.
Put the hood aside for a few minutes to allow
any fuel vapors to escape. Also, check for
loose electrical connections.
WARNING@Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or loose electrical connection.
@
EJU00427
Fuel system
Check the fuel system for leakage, cracks or
malfunctions before each use. (See page 4-10
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, and then check the
fuel level in the tank. Replenish if neces-
sary. (See page 3-4 for filling instruc-
tions.)
3. Close the fuel tank filler cap securely.

Fire extinguisher
Check that there is a full fire extinguisher
on board. The fire extinguisher container 1
is on the hood under the steering pole.
To open the fire extinguisher container:
1. Grasp the tab 2, pull the band to the
rear, and then pull up.
2. Lift the container about 30 degrees from
the stored position.
3. Remove the cap to reach the fire extin-
guisher.
CAUTION:@Do not force the fire extinguisher con-
tainer up more than 30 degrees from the
storage position, otherwise the container
or hood could be damaged.
@
To close the fire extinguisher container:
1. Reinstall the cap and tighten it securely
after inserting the fire extinguisher into
the container.
2. Reinstall the container on the hood and
secure it with the band.
NOTE:@●See the instructions supplied by the fire
extinguisher manufacturer for checking
the fire extinguisher. Always keep the
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.

Throttle
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 complete range, and spring back to
the idle position when released.
WARNING
Before starting the engine, always check
the operation of the throttle lever. It
should move smoothly through its full
range of operation, and should spring
back to the idle position when released.
EJU00448
Steering system
Check for looseness in the handlebars.
Turn them as far as possible to the right and
left to make sure that operation is smooth
and unrestricted throughout the whole
range. Make sure that the jet thrust nozzle
also changes directions as the handlebars
are turned, and that there is no free play
between the handlebars and the jet thrust
nozzle.
EJU00449
Steering pole
Check for looseness in the steering pole.
Move it up and down to make sure operation
is smooth and unrestricted throughout the
whole range. Make sure the steering pole
does not have any side play.
