EJU30850
Hazard information

When transporting or storing your water-
craft, always turn the fuel cock knob to
“OFF”, 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 color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.
EJU30880
Watercraft characteristics

Jet thrust turns the watercraft. Releasing
the throttle lever completely produces only
minimum thrust. If you are traveling at
speeds above trolling, you will have rapidly
decreasing ability to steer without throttle.
You may still have some turning ability im-
mediately after releasing the throttle lever,
but once the engine slows down, the water-
craft will no longer respond to handlebar in-
put until you apply throttle again or you
reach trolling speed.
Practice turning in an open area without ob-
stacles until you have a good feel for this
maneuver.

This watercraft is water-jet propelled. The
jet pump is directly connected to the engine.
This means that jet thrust will produce some
movement whenever the engine is running.
There is no “neutral” position.

Keep away from the intake grate while the
engine is on. Items such as long hair, loose
clothing, or PFD straps can become entan-
gled in moving parts, resulting in severe in-
jury or drowning.

Never insert any object into the jet thrust
nozzle while the engine is running. Severe
injury or death could result from coming in

Operation
WARNING
EWJ00510
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
EJU32750Engine break-in
The engine break-in period is essential to al-
low the various components of the engine to
wear and polish themselves to the correct op-
erating clearances. This ensures proper per-
formance and promotes longer component
life.
CAUTION:
ECJ00420

For the first 5 hours of operation or 2
tankfuls of fuel, premix the fuel in a fuel-
to-oil ratio of 25:1.

After break-in, premix the fuel in a fuel-
to-oil ratio of 50:1 for normal operation.
(1) Launch the watercraft, start the engine,
and then board the watercraft. (See page
33 for engine starting procedures.)
(2) Run the engine at the lowest possible
speed for 5 minutes.
(3) Gradually apply throttle to 3/4 or less.
(4) Operate the watercraft at 3/4 throttle or
less for the first tankful of fuel.
(5) Fill the fuel tank once more with fuel in a
fuel-to-oil ratio of 25:1, and then proceed
with normal operation.
CAUTION:
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
EJU32820Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles around you.
After the watercraft is in the water, turn it
around so that the bow faces the direction you
wish to go. Start the engine, and then slowly
move away from the launching area. If there
are waves, someone should make sure that
the watercraft is not pushed into the trailer af-
ter launching the watercraft.
EJU32830Starting the engine
WARNING
EWJ00560
Never start the engine or let it run for any
length of time in an enclosed area. Ex-
haust 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.
(1) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep.

Trouble recovery
67

The bow must be kept up out of the wa-
ter during towing to prevent water from
entering the engine compartment.
WARNING
EWJ00810

The watercraft should only be towed in
an emergency.

The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down. A
good rule of thumb is a towline that is
three times the combined length of the
towing boat and the watercraft.

The operator of the towing boat must
keep speed to a minimum and avoid traf-
fic or obstacles which could be a hazard
to the rider on the watercraft.
EJU34730Submerged watercraft
If the watercraft is submerged or flooded with
water, follow the procedure below and consult
a Yamaha dealer as soon as possible. Failure
to do so could result in serious engine dam-
age!
In an emergency:
(1) Beach the watercraft and remove the
hood. Turn the watercraft over far enough
to drain the water from the engine com-
partment.
CAUTION:
ECJ00700
Turning the watercraft on its side with the
hood removed could cause damage to the
steering pole. Use two people to provide
enough support to make sure that the
steering pole is not damaged.
(2) Turn the watercraft upright again.
(3) Turn the fuel cock knob to “OFF”.
(4) Remove the spark plugs and dry them
with a cloth.
(5) Without reinstalling the spark plugs,
crank the engine until all of the water in
the cylinders has been drained.
(6) Install the spark plugs and the hood.
(7) Turn the fuel cock knob to “ON”.
(8) Launch the watercraft into the water, and
then run the engine for at least 10 min-
utes. If the engine does not start, repeat
steps 3–8.
(9) Shut the engine off.
(10) Turn the fuel cock knob to “OFF”, remove
the silencer cap, and then spray a rust in-
hibitor into the carburetor while cranking
the engine.
(11) Have the watercraft inspected by a
Yamaha dealer as soon as possible.
