(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

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.

EJU40182Engine unit check
Check the exterior of the engine unit for dam-
age or other problem.
EJU36886Engine oil level check
Make sure that the engine oil level is between
the minimum and maximum level marks on
the dipstick. (See page 51 for information on
checking the engine oil level.)
EJU32456Bilge water check
Make sure that no bilge water has collected in
the engine compartment. If bilge water has
collected in the engine compartment, drain it.
(See page 52 for information on draining the
bilge water.)
EJU32485Battery checks
Make sure that the battery terminals and
breather hose are not damaged and that thebattery leads and breather hose are connect-
ed properly.
WARNING! Fire or explosion
could result if the breather hose is dam-
aged, obstructed, or not connected prop-
erly.
[EWJ00452]
Make sure that the electrolyte level is be-
tween the minimum and maximum level
marks. WARNING! Never operate the wa-
tercraft if the battery does not have suffi-
cient power to start the engine or if it
shows any other signs of decreased pow-
er. Loss of battery power may leave you
stranded.
[EWJ01241]
Make sure that the battery is securely held in
place.

ter flows out continually from the jet
thrust nozzle.
(7) Run the engine at idling speed for about 3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
perform the procedure again from step 6.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00123]
(8) Turn the water supply off.
(9) Discharge the remaining water out of the cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(10) Stop the engine.
(11) Remove the garden hose adapter, and then securely install the flushing hose
connector cap by tightening it until it
stops.
(12) Securely install the watertight storage compartment and seats in their original
positions.
EJU33736Cleaning the watercraft
(1) Remove the seats. (See page 41 for seatremoval and installation procedures.)
(2) 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.
[ECJ00572]
(3) Drain the water from the engine com- partment. (See page 52 for information
on draining the bilge water.)
(4) Wipe the engine and engine compart- ment with a dry cloth.
(5) Wash down the hull, deck, and jet pump with fresh water.
(6) Wipe the hull, deck, and jet pump with a dry cloth.
(7) Wipe all vinyl and rubber components, such as the seats and engine compart-
ment seals, with a vinyl protectant.
(8) To minimize corrosion, spray metallic parts of the hull, deck, and engine with a
rust inhibitor.
(9) Allow the engine compartment to air dry completely before installing the seats.
(10) Securely install the seats in their original positions.
EJU33687Battery care
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft, check it, and then store it in a cool, dry
place.
WARNING
EWJ00792
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
