EJU36882Engine oil level
Check the engine oil level before each use.
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.
NOTICE
ECJ01001
Make sure that debris and water do not en-
ter 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 level
position on land with the engine stopped.
TIP:
If the engine was running, allow the engine oil
to settle by waiting 5 minutes or more before
checking the oil level.
(2) Remove the seats. (See page 23 for seat

tween the minimum and maximum level
marks.
(4) If the engine oil level is below the mini-
mum level mark, perform steps 5–7 to
add enough oil so that the oil level is be-
tween the minimum and maximum level
marks on the dipstick. If the engine oil lev-
el is significantly above the maximum lev-
el mark, have a Yamaha dealer service
the watercraft.(5) Remove the engine oil filler cap.
(6) Pour engine oil into the filler hole. Wait
approximately 5 minutes until the engine
oil settles.
TIP:
The difference between the minimum and
maximum level marks on the dipstick is equal
to approximately 1 liter of engine oil.
(7) Repeat steps 3–6 until the engine oil is at
the proper level.
(8) Install the engine oil filler cap, and then
install the seats.
EJU32420Water separator

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.
EJU32452Bilge
Check the bilge for moisture and fuel residue.
NOTICE: Excessive water in the engine
compartment can splash into the engine,
which can result in severe damage.
[ECJ00341]
This watercraft is equipped with a convention-
al jet vacuum bilge draining system and an
electric bilge draining system. The electric
bilge draining system is operated when the
engine is running. When excess water reach-
es the water inlet of the electric bilge pump,
the water is discharged from the electric bilge
pilot outlet at the stern.
A small quantity of water will remain in the
bilge and should be drained manually. To
drain any residual water, beach the watercraft
and perform the following procedure.
To drain water from the bilge:
(1) Remove the stern drain plugs.
(2) Raise the bow of the watercraft until the
water drains.(3) After the water has drained, wipe the
bilge with dry rags to make sure that it is
thoroughly dry.
(4) Install the stern drain plugs. NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads 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. Make
sure that the stern drain plugs are
tightened securely before launching
the watercraft. Otherwise, water may
flood the engine compartment and
cause the watercraft to submerge.

EJU32651Jet intake
Carefully check the jet intake for weeds, de-
bris, or anything else that might restrict the in-
take of water. If the jet intake is clogged, clean
it. (See page 83 for jet intake cleaning proce-
dures.)
If the watercraft is operated while the jet in-
take is clogged, cavitation could occur, reduc-
ing jet thrust, and possibly damaging the jet
pump. In some cases, the engine may over-
heat because of lack of cooling water, and
damage to the engine could result. Cooling
water is fed to the engine by the jet pump.
EJU32661Engine shut-off cord (lanyard)
Check that the engine shut-off cord (lanyard)
is not frayed or broken. If the cord is dam-
aged, replace it. WARNING! Never try to re-
pair the engine shut-off cord (lanyard) or
tie it together. The engine shut-off cord
(lanyard) may not pull free when the oper-
ator falls off, allowing the watercraft tocontinue to run and cause an accident.
