tank. Contaminated fuel can cause poor
running and engine damage.
(1) Remove the seat. (See page 26 for seat
removal and installation procedures.)

slowly add fuel to the fuel tank. Stop filling
when the fuel level reaches approximate-ly 50 mm (2 in) from the top of the fuel
tank as indicated in the illustration.
(3) Install the fuel tank filler cap and the seat.

Operation

EJU32280Pre-operation check points EJU32310Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seat. (See page 26 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.
EJU32390Fuel level
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
73 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 seat. (See page 26 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 42 for
filling procedures.)
(4) Install the fuel tank filler cap and the seat.
EJU32400Engine 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 66 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.

NOTE:
If the ambient temperature is 20 °C (68 °F) or
less, warm up the engine for an additional 5
minutes.
(3) Remove the seat. (See page 26 for seat
removal and installation procedures.)
(4) Remove the oil tank filler cap, wipe the
dipstick clean, and then screw the filler
cap into the filler hole completely. Re-
move the filler cap again and check that
the engine oil level is between the mini-
mum level mark and maximum level
mark on the dipstick.
(5) If the engine oil level is below the mini-
mum level mark, add enough oil so that
the oil level is between the minimum and
maximum level marks on the dipstick,and then install the filler cap. If the engine
oil level is significantly above the maxi-
mum level mark, the oil tank is overfilled.
Have a Yamaha dealer remove the ex-
cessive amount of engine oil.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
draining water or use a dry cloth to soak up
any water that could spill into the watercraft. If
any water spills into the watercraft, be sure to
wipe it up with a dry cloth. Also, be sure to in-
stall the drain screw after draining the water
separator.
EJU32460Bilge
Check the bilge for moisture and fuel residue.
CAUTION:
ECJ00370
Excessive water in the bilge can splash
into the engine, which can result in severe
damage.

EJU32710Multifunction information center
Check the multifunction information center for
proper operation. (See page 34 for informa-
tion on proper operation of the multifunction
information center.)
EJU32740
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.
CAUTION:
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU32781Engine 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:
ECJ00440
Be sure to check the engine oil level be-
fore operating the watercraft for the first
time. (See page 45 for engine oil checking
procedures.)

(6) Gradually increase the speed to balance
the watercraft.
EJU33230Capsized watercraft
If the watercraft capsizes, turn it over immedi-
ately.
Be sure to carefully follow the procedures be-
low to prevent injury, or damage to the water-
craft.
WARNING
EWJ00670
IMPROPER UPRIGHTING CAN CAUSE IN-
JURY:

Be sure to shut the engine off by pulling
on the engine shut-off cord to remove
the clip from the engine shut-off switch.

Do not put your hands in the intake
grate.
CAUTION:
ECJ00530
If the watercraft capsizes, release the
throttle lever immediately. Oil could flow
into the air filter case and the engine could
be damaged.
(1) Remove the clip from the engine shut-off
switch.
(2) Swim to the rear of the watercraft. Pull the
watercraft over with your left hand on theride plate while pushing down on the gun-
wale with your right hand or foot.
NOTE:
If the port (left) side of the capsized watercraft
is tilting up, push down on the gunwale so that
the port (left) side is down before turning the
watercraft clockwise.
CAUTION:
ECJ00540
Do not turn the watercraft over counter-
clockwise, otherwise water can enter the
engine, which can result in severe dam-
age.
(3) Start the engine and operate the water-
craft to discharge any water remaining in
the engine compartment. (If the engine
does not start, see “Towing the water-
craft” on page 85 or “Submerged water-
craft” on page 85.)

EJU34210Checking the fuel system
WARNING
EWJ00380
Gasoline is highly flammable and explo-
sive. Failure to check for and repair any
fuel leakage could result in a fire or explo-
sion. A fire or explosion can cause severe
injury or death. Shut the engine off. Do not
smoke. Avoid spilling gasoline.
Fuel in the fuel lines is pressurized.
Fuel can spray out and cause injury or a
fire hazard if a fuel line is disconnected.
Do not run the engine with a fuel line dis-
connected.
Check the fuel system for leaks, cracks, and
malfunctions. If any problem is found, consult
a Yamaha dealer.
Check:

Fuel tank filler cap and seal for damage.

Fuel in fuel tank for water and dirt.

Fuel tank for damage, cracks, and leakage.

Fuel hoses and joints for damage, cracks,
and leakage.

Air bleeding passages for leakage.EJU34230Fuel tank
Check the fuel tank for leakage and for water
in the tank. If water is found in the fuel system,
or if the fuel tank needs to be cleaned, have a
Yamaha dealer service the watercraft.
EJU34290Engine oil and oil filter
WARNING
EWJ00340
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
CAUTION:
ECJ00180

Do not run the engine with too much or
not enough oil in the oil tank. Oil could
spray out and the engine could be dam-
aged.

Be sure to change the engine oil after
the first 10 hours of operation, and every
100 hours thereafter or at the start of a
new season, otherwise the engine will
wear quickly.
The oil filter should be replaced every
year or every 100 hours of operation.
Have a Yamaha dealer replace the oil fil-
ter if necessary.
It is recommended to have a Yamaha dealer
change the engine oil. However, if you choose
to change the oil on your own, consult a
Yamaha dealer.
NOTE:
Dispose of used oil according to local regula-
tions.
