Features and functions

When the engine is running, cooling water is
circulated in the engine, and then it is dis-
charged 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 oc-
curs, stop the engine and check for the cause.
(See pages 22 and 63 for more information.)
TIP:

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.

Water discharge may not be constant at
idle, therefore, open the throttle a little to
check that water discharges properly.
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.The bow rope hole is used to attach a rope to
the watercraft when transporting, mooring, or
towing it in an emergency.
EJU36010Stern rope hole
The stern rope hole is located at the stern of
the watercraft.
The stern rope hole is used to attach a rope to
the watercraft when mooring it.
EJU31661Engine overheat warning system
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the engine
speed will be limited to about 3400 r/min.
If this occurs, immediately reduce the engine
speed, return to shore, and then check for wa-
ter discharge at the cooling water pilot outlet
while the engine is running. If there is no dis-
charge of water, check the intake grate and

Operation
25
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.

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.
