Engine oil requirementsEJU41513Engine oil
NOTICE
ECJ00282
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
TIP:
When the engine is operated at high speeds,
some engine oil may be consumed. Be sure
to check the engine oil level.
Checking the engine oil level
WARNING
EWJ00341
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.
NOTICE
ECJ01002
Make sure that debris and water do not
enter the oil 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 precisely levelposition on land with the engine
stopped. If the engine was running, allow
the engine oil to settle by waiting 5 min-
utes or more before checking the oil lev-
el.
(2) Remove the seats. (See page 41 for seat removal and installation procedures.) (3) Remove the dipstick and wipe it clean.
(4) Insert the dipstick
back into the dipstick
tube 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.
Recommended engine oil type:
SAE 10W-30, 10W-40, 20W-40,
20W-50
Recommended engine oil grade: API SE,SF,SG,SH,SJ,SL

(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 water
NOTICE
ECJ01302
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.
EJU40035Draining 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-1Engine oil filler cap

maining moisture in the engine compart-
ment with a dry cloth.
(4) Securely install the stern drain plugs by tightening them until they stop. 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, allowing water to enter
the engine compartment. Check the
O-rings on the stern drain plugs and
make sure that the plugs are tightened
securely before launching the water-
craft. Otherwise, water may flood the
engine compartment and cause the
watercraft to submerge.

EJU40044
Draining 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-
gine has been restarted. Bilge water in the
engine compartment can splash into the engine, which can result in severe dam-
age.
[ECJ00554]
Electric bilge draining system
Bilge water in the engine compartment is
drawn in by the operation of the electric bilge
pump and discharged from the watercraft.
To check for proper operation of the electric
bilge draining system, make sure that bilge
water is being discharged from the electric
bilge pilot outlet.
To drain the bilge water:
Start the engine to operate the electric bilge
pump.
TIP:
The electric bilge pump continues to operate
for a short time after the engine stops.

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. Do not transport the water-
craft with the shift lever in the reverse po-
sition. Otherwise, the reverse gate may hit
an obstacle, which could cause damage.

Engine break-in
NOTICE
ECJ00432
Failure to perform the engine break-in
could result in reduced engine life or even
severe engine damage.
The engine break-in is essential to allow the
various components of the engine to wear
and polish themselves to the correct operat-
ing clearances. This ensures proper perfor-
mance and promotes longer component life.
To perform the engine break-in:
(1) Check the engine oil level. (See page 51for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en- gine. (See page 68 for information on
starting the engine.)
(3) For the first 5 minutes, operate with the engine speed at 2000 r/min.
(4) For the next 90 minutes, operate with the engine speed below 5000 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.

EJU32334Engine compartment check
WARNING
EWJ00462
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.
Ventilate the engine compartment. Leave the
engine compartment open for a few minutes
to allow any fuel vapors to escape.
Make sure that there is no damage inside the
engine compartment.
EJU34215Fuel system checks
WARNING
EWJ00382
Leaking fuel can result in fire or explosion.
Check for fuel leakage regularly.
If any fuel leakage is found, the fuel sys-
tem must be repaired by a qualified me-
chanic. Improper repairs can make the
watercraft unsafe to operate.
Make sure that there is no damage, leakage,
or other problem in the fuel system.
Check:
Fuel filler cap and seal for damage
Fuel tank for damage and leakage
Fuel hoses and joints for damage and leak-
age
