EJU32280Pre-operation check points EJU32291Engine compartment
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.
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 17 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.
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.
EJU32361Fuel system
Make sure that there is sufficient fuel in the
fuel tank before each use.
Also, check the fuel system for leakage,
cracks, and malfunctions. (See page 51 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 17 for hood
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 25 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

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.
EJU32752Engine break-in
NOTICE
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
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.
(1) Fill the fuel tank with fuel in a fuel-to-oil ra-
tio of 25:1.
(2) Launch the watercraft, start the engine,
and then board the watercraft. (See page
32 for engine starting procedures.)
(3) Run the engine at the lowest possible
speed for 5 minutes.
(4) Gradually apply throttle to 3/4 or less.
(5) Operate the watercraft at 3/4 throttle or
less for the first tankful of fuel.
(6) Fill the fuel tank once more with fuel in a
fuel-to-oil ratio of 25:1, and then proceed
with normal operation.
(7) After break-in, fill the fuel tank with fuel in
a fuel-to-oil ratio of 50:1.
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.
EJU32832Starting the engine
(1) Remove the fuel tank filler cap to release
any built-up pressure in the fuel tank due
to fuel expansion, and then install the fill-
er cap.
(2) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep from the bottom of the watercraft.
NOTICE: Never operate in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise
pebbles or sand could be sucked into

(5) Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See
page 45 for flushing procedures.)
(6) If the watercraft will be stored for a week
or more, lubricate internal engine compo-
nents to help prevent corrosion. (See
page 46 for lubrication procedures.)
(7) Rinse the engine and engine compart-
ment with a small amount of water.
NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.
[ECJ00571]
(8) Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3,
if necessary).
(9) Wipe the hull, steering pole, handlebars,
and jet unit dry with a clean cloth.
(10) Spray a rust inhibitor on metallic parts to
minimize corrosion.
(11) Allow the engine compartment to air dry
completely before installing the hood.
EJU33421
Transporting
WARNING
EWJ00750
Always turn the fuel cock knob to “OFF”
when transporting the watercraft, other-
wise fuel could leak out into the engine or
engine compartment, which would create
a fire hazard.
Transport this watercraft using a special trail-
er that incorporates a hole into which the pin
can be inserted and locked after passing it
through the bow rope hole.
After securing the bow with the pin, secure the
stern with ropes or tie downs routed over the
gunwales. Use a rubber shock cord to secure
the steering pole to the watercraft. NOTICE:
Do not secure the steering pole with ropes
or tie downs and do not secure it to the
