●Attach the engine shut-off cord (lanyard)
to wrist and keep it free from the handle-
bars so that the engine stops if the opera-
tor falls off. After riding, remove the
engine shut-off cord from the watercraft to
avoid accidental starting or unauthorized
use by children or others.
●Scan carefully for swimmers, and stay
away from swimming areas. Swimmers
are hard to see and you could acciden-
tally hit someone in the water.
●Avoid being hit by another boat! You
should always take the responsibility to
watch for traffic; other boaters may not be
watching for you. If they do not see you,
or you maneuver more quickly than other
boaters expect, you risk a collision.
●Maintain a safe distance from other boats
or watercraft, and also watch for boats’ ski
ropes or fishing lines. Obey the “Safe
boating rules” and be sure to check
behind you before making a turn. (See
Safe boating rules on page 1-14.)

Hazard information
●When transporting or storing your water-
craft, always place the fuel cock knob in
the “OFF” position, otherwise gasoline
may overflow from the carburetor.
●Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monoxide,
a colorless, odorless gas that may cause
loss of consciousness and death within a
short time. Always operate the watercraft
in an open area.

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.

Pre-operation check list
Before operating this watercraft, perform the checks in the following check list. See the
accompanying text in this chapter for details on how to perform the checks.
WARNING@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 thoroughly each time the watercraft is used. This pro-
cedure can be completed in a short time. It is worth the time spent to assure safety and reli-
ability.

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.

Switches
Check the start switch 1, the engine stop
switch 2 and the engine shut-off switch 4
for proper operation. To check these
switches place the watercraft in the water to
provide adequate engine cooling. Start the
engine, and then pull the engine shut-off
cord5 to remove the clip 3 from the
engine shut-off switch. Verify that the engine
stops immediately. (See pages 3-15 to 3-18
for information on proper operation of the
start switch, the engine stop switch and the
engine shut-off switch.)
EJU00453
Cooling water pilot outlet
Check that water comes out from the out-
let while the engine is running and the
watercraft is in the water.

3. Attach the clip 1 to the engine shut-off
switch 2. Also, attach the engine shut
off cord 3 to your wrist.
WARNING@Check that the engine shut-off cord is not
frayed or broken, and keep it free from
the handlebars so the engine stops if the
operator falls off. The engine shut-off
cord may not pull free if wrapped around
the handlebars when the operator falls
off, allowing the watercraft to continue to
run and cause an accident.
@
NOTE:@It is not possible to start the engine with the
clip removed from the engine shut-off
switch.
@
4. Pull and hold the choke knob all the way
out.
NOTE:@The choke should not be used when the
engine is warm.
@
5. While lightly squeezing the throttle lever,
push the start switch.
WARNING@On this watercraft, the engine is con-
nected directly to the jet pump. Starting
the engine immediately generates some
thrust. Apply only enough throttle to
keep the engine running.
