EJU31050Hood
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 to the open position,
and then pull up on the hood latch to un-
latch the hood.(2) Grasp the hood using the handgrips pro-
vided at the front and rear 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 that the
two projections at the front of the hood fit
under the two stays on the deck.
(2) Push down on the hood latch, and then
turn the knob to the lock position.

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.

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
