(3) Remove the seats, and then check thefuel level. (See page 69 for seat removal
and installation procedures.)
(4) Loosen the fuel filler cap and remove it.
(5) Slowly add fuel to the fuel tank.
(6) Stop filling when the fuel level reaches approximately 50 mm (2 in) from the top
of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it
heats up, heat from the engine or the sun
can cause fuel to spill out of the fuel tank.
Do not leave the watercraft with a full
tank in direct sunlight. (7) Wipe up any spilled fuel immediately with
a dry cloth.
(8) Securely install the fuel filler cap by tight- ening it until it clicks.
(9) Securely install the seats in their original positions.

(4) Insert the dipstick back into the dipsticktube completely. Remove the dipstick
again and make sure that the engine oil
level is between the minimum and maxi-
mum level marks.
(5) If the engine oil level is significantly above the maximum level mark, consult
a Yamaha dealer. If the engine oil level is
below the minimum level mark, add en-
gine oil.
(6) Loosen the engine oil filler cap and re- move it. (7) Slowly add engine oil.
TIP
The difference between the minimum and
maximum level marks on the dipstick is equal
to approximately 1 L (1.06 US qt, 0.88 Imp.qt)
of engine oil.
(8) Wait approximately 5 minutes to allow
the engine oil to settle, and then check
the engine oil level again.
(9) Repeat steps 3–8 until the engine oil is at the proper level.
(10) Securely install the engine oil filler cap by tightening it until it stops.
(11) Securely install the seats in their original positions.

Draining the bilge waterECJ01302
Do not run the engine at full throttle when
bilge water remains in the engine com-
partment. The bilge water can splash into
the engine, which can result in severe
damage.
EJU44262Draining the bilge water on land
To drain the bilge water on land:
(1) Loosen the stern drain plugs and removethem.
(2) Raise the bow of the watercraft, such as by placing the watercraft on a slope, to
drain the bilge water from the engine
compartment.
(3) After the bilge water has drained from the stern drain plug holes, wipe up any re-
maining moisture in the engine compart-
ment with a dry cloth.
(4) Check that the stern drain plugs and O- rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs.
NOTICE: Before installing the stern
drain plugs, clean the drain plug
threads and the O-rings on the plugs
to remove any foreign materials, such as dirt or sand. Otherwise, the stern
drain plugs could be damaged, allow-
ing water to enter the engine compart-
ment. Check the O-rings on the stern
drain plugs and make sure that the
plugs are tightened securely before
launching the watercraft. Otherwise,
water may flood the engine compart-
ment and cause the watercraft to sub-
merge.
[ECJ00364]
(5) Securely install the stern drain plugs by
tightening them until they stop.
EJU40536Draining the bilge water on water
A small quantity of bilge water will remain in
the engine compartment even after the bilge
water is drained on water. To completely
drain the bilge water, remove the watercraft
from the water and drain the bilge water on
land.
Jet vacuum bilge draining system
While the watercraft is operating, bilge water
in the engine compartment is drawn in by the
vacuum that is generated in the jet pump and
discharged from the watercraft through the
jet thrust nozzle.
To drain the bilge water on water:
Operate the watercraft as straight as possible
and above planing speed for at least 2 min-
utes. NOTICE: Do not run the engine at full
throttle for at least 1 minute after the en-

age.
[ECJ00554]EJU42433
Transporting on a trailer
When transporting the watercraft on a trailer,
secure the tie downs to the trailer through the
bow eye and stern eyes.
NOTICE: Do not at-
tach ropes or tie downs to any part of the
watercraft other than the bow eye and
stern eyes to secure the watercraft to the
trailer. Otherwise, the watercraft may be
damaged. Wrap the ropes or tie downs
with towels or rags where they touch the
body of the watercraft to avoid scratches
or damage.
