Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment
remove the rear and front seats. (See pages
2-4 to 2-5 for seat removal and installation
procedures.) Allow the engine compartment
to remain open 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 a loose electrical connection.

EJU01318
Fuel and oil systems
Check the fuel system for leakage, cracks
or malfunctions before each use. (See page
4-9 for check points and correct proce-
dures.)
1. Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
2. Remove the rear and front seats. (See
pages 2-4 to 2-5 for seat removal and
installation procedures.)
3. Check the fuel and oil levels in the tanks
and replenish if necessary. (See pages

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.
@
EJU01244
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 han-
dlebars are turned, and that there is no free
play between the handlebars and the jet
thrust nozzle.
Check that the tilt adjustment is locked in
position. (See Tilt lever on page 2-12.)

Shift lever and reverse gate
Check for proper operation of the shift
lever and reverse gate.
Make sure that the reverse gate goes
down to its stopper position when the shift
lever is pulled up.
Also, make sure that the reverse gate
goes up to its stopper position when shift
lever is pushed down.
WARNING@
Make sure that the throttle is com-
pletely released and that the engine is
at idle before shifting into reverse.

Do not use the reverse function to
slow down or stop the watercraft as it
could cause you to lose control, be
ejected, or impact the handlebars.

Use reverse for slow-speed maneuver-
ing only.

Make sure that there are no obstacles
or people behind you before shifting
into reverse.

Do not touch the reverse gate while the
shift lever is being operated, otherwise
you could be pinched.

Jet unit
Carefully check the jet intake for weeds,
debris, or anything else that might restrict
the intake of water. If the intake is clogged,
cavitation could occur, reducing jet thrust,
and possibly damaging the jet pump.
In some cases, the engine may overheat
because of lack of cooling water, and dam-
age to the engine could result. Engine cool-
ing water is fed to the engine by the jet
pump. (See page 5-4 for jet intake cleaning
procedures.)
WARNING@
Keep away from intake grate while
engine is on. Items such as long hair,
loose clothing, or PFD straps can
become entangled in moving parts
resulting in severe injury or drowning.

Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds, which
may have collected around the jet
intake.

EJU01059
Engine shut-off cord (lanyard)
Check that the engine shut-off cord is not
frayed or broken. If the cord is damaged,
replace it; never try to repair it or tie it
together.

Operation
WARNING@ Before operating your watercraft,
become familiar with all controls. Con-
sult your Yamaha dealer about any con-
trol or function you do not fully
understand. Failure to understand how
controls work could cause an accident or
prevent you from avoiding an accident.
@
CAUTION:@ Make sure that stern drain plugs are
securely tightened before launching the
watercraft.
@
EJU01064
Engine break-in
The engine break-in period is essential to
allow the various components of the engine
to wear and polish themselves to the correct
operating clearances. This ensures proper
performance and promotes longer compo-
nent life.
CAUTION:@
For the first tankful of operation, pre-
mix a 50:1 mixture of fuel and oil (in
addition to the oil in the oil tank).

After break-in, use straight gasoline
for normal operation.
@
1. Launch the watercraft and start the
engine. (See pages 3-16 to 3-18 for
engine starting procedures.)
2. Run the engine at the lowest possible
speed for 5 minutes.

Launching the watercraft
Make sure that there are no obstructions
behind you.
After the watercraft is in the water, start
the engine. Shift into reverse and move the
watercraft back slowly. If there are waves,
someone should make sure that the water-
craft is not pushed into the trailer before
backing away.
EJU01248
Starting the engine
WARNING@ Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monox-
ide, a colorless, odorless gas that may
cause loss of consciousness and death
within a short time. Always operate the
watercraft in an open area.
@
1. Launch the watercraft in water free from
weeds and debris and at least 60 cm
(2 ft) deep.
WARNING@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged
object, which could result in injury.
@
CAUTION:@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise pebbles or
sand could be sucked into the jet intake,
causing impeller damage or engine over-
heating.

2. Turn the fuel cock knob to the “ON” posi-
tion.
NOTE:
Before starting the watercraft, after it has
been sitting, remove the fuel tank filler cap
to release any built-up pressure in the tank
due to fuel expansion.
3. Attach the clip 1 to the engine shut-off
switch 2. Also, attach the engine shut-
off cord 3 to your left 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 to start a cold engine.
NOTE:@ The choke should not be used when the

5. If the “LOCK” mode was chosen previ-
ously, choose the “START” mode before
starting the engine. (See pages 2-20 to
2-21 for selecting “PA D L O C” mode.)
NOTE:@
If the initial setting of the PADLOC has not
been done, the “START” mode is auto-
matically selected.

If you have previously chosen “LOCK”
mode, the engine will not start unless the
correct code is entered. This selects the
“START” mode.
@
6. While lightly squeezing the throttle lever,
push the start switch (green button).
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.
@
7. Release the start switch as soon as the
engine starts to run.
CAUTION:@
Never push the start switch while the
engine is running.

Do not operate the start switch for
more than 5 seconds, otherwise the
battery will be discharged and the
engine will not start. Also, the starter
motor may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
try again.
@
8. After the engine has warmed up, push
the choke knob in to its original position.
NOTE:@ If the choke knob is left pulled out, the
engine will stall.
