Operation
53
EJU32280Pre-operation check points EJU32330Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seats. (See page 24 for seat 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.
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.
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.
EJU32380Fuel level
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
83 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 seats. (See page 24 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 50 for
filling procedures.)
(4) Install the fuel tank filler cap and the
seats.
EJU32411Engine oil level
Check the engine oil level before each use.
CAUTION:
ECJ00390

When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and wind can cause the
watercraft to move and lead to a colli-
sion.

When checking the engine oil level on
land, supply water to the cooling water
passages. (See page 76 for procedures
on supplying water.)

Make sure that the engine has enough
oil, but do not overfill it. If there is too lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter can be-
come saturated with oil, permanently
damaging the filter and reducing engine
performance. Follow the checking pro-
cedure carefully.

Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
To check the engine oil level:
(1) Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.

water passages by alternately squeezing
and releasing the throttle lever for 10 to
15 seconds, making sure not to run the
engine over 6000 r/min.
(8) Stop the engine.
(9) Remove the garden hose adapter and in-
stall the flushing hose connector cap.
EJU33600Lubrication
WARNING
EWJ00260
Do not spray flammable rust inhibitor
products on engine surfaces while the en-
gine is hot. The sprayed substance or pro-
pellants could catch fire.
(1) Remove the seats. (See page 24 for seat
removal and installation procedures.)
(2) Remove the air filter case cover and the
air filter element. (See page 84 for air fil-
ter case cover and air filter element re-
moval and installation procedures.)
(3) Spray a rust inhibitor into each intake
opening for 3 seconds.
(4) Install the air filter element in the air filter
case, and then install the air filter case
cover.
(5) Start the engine in a well-ventilated area
and let it run at idle for 15 seconds.
CAUTION:
ECJ00160
Do not run the engine for more than 15
seconds, otherwise the engine could over-
heat.
(6) Lubricate all cables such as the throttle
and steering cables.
NOTE:
Use a suitable marine grease applicator to
pressure-lubricate the cables and purge out
any moisture between the inner and outer ca-
bles.
(7) Lubricate the areas of the watercraft
specified in “Lubrication points” on page
87.
EJU36380Fuel system
WARNING
EWJ00280
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and keep
away from sparks, flames, and other
sources of ignition.

Stop the engine before refueling.

Refuel in a well-ventilated area with the
watercraft in a horizontal position.

Do not stand or sit on the watercraft
while refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level reaches approxi-
mately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do not

leave it in direct sunlight. Leave it in a
well-ventilated area with the watercraft
in a horizontal position.

Tighten the fuel tank filler cap securely
after refueling.

If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso-
line in your eyes, get immediate medical
attention.

If any gasoline spills on your skin or
clothing, immediately wash the affected
area with soap and water and change
your clothes.
Add approximately 550 ml (18.6 US oz, 19.4
Imp oz) of Yamaha Fuel Stabilizer and Condi-
tioner to the fuel tank, and then top it off with
fresh gasoline.
CAUTION:
ECJ00140
Use only Yamaha Fuel Stabilizer and Con-
ditioner, otherwise the catalytic converter
could be seriously damaged.
EJU33680Battery
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft and store it in a cool, dry place.
(1) Disconnect the negative (–) battery lead
first, then the positive (+) battery lead and
breather hose, and then remove the bat-
tery from the watercraft.
(2) Clean the battery casing using fresh wa-
ter.
(3) If the battery terminals are dirty or corrod-
ed, clean them with a wire brush.
(4) Fully charge the battery.
(5) Apply Yamaha Marine Grease or
Yamaha Grease A to the battery termi-
nals, and then store the battery in a cool,
dry place.(6) Check the battery at least once every 2
months and fully charge it if necessary.
CAUTION:
ECJ00100
Always keep the battery charged. Storing
a discharged battery can cause permanent
battery damage.
To check the condition of the battery, check
the specific gravity of the electrolyte or mea-
sure the voltage at both battery terminals.
Charge the battery if the voltage is less than
12 volts.
It is recommended to have a Yamaha dealer
check the specific gravity and charge the bat-
tery. If you maintain the battery yourself, be
sure to read and follow the instructions provid-
ed with the battery tester and charger you
use.
EJU33730Cleaning the watercraft
Clean the watercraft before storing it for a long
period.
(1) Wash down the hull, handlebars, and jet
unit with fresh water.
(2) Rinse the engine and bilge area with
fresh water. Drain all of the water and
wipe up any remaining moisture with
clean, dry rags.
CAUTION:
ECJ00110
Do not use high-pressure water when rins-
ing the engine and bilge area as severe en-
gine damage could result.
(3) Spray the engine’s exterior with a rust in-
hibitor and lubricant.
(4) Wax the hull with a non-abrasive wax.Specific gravity (for reference):
1.28 at 20 °C (68 °F)
