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
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.

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.
NOTICE
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU36661Engine break-in
NOTICE
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
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.
TIP:
Be sure to check the engine oil level before
operating the watercraft for the first time. (See
page 45 for engine oil checking procedures.)
(1) Launch the watercraft and start the en-
gine. (See page 53 for engine starting
procedures.)
(2) For the first 5 minutes, run the engine at
trolling speed only. For the 30 minutes of
operation after that, keep the engine
speed below 5000 r/min. For the 1 hour of
operation after that, keep the engine
speed below 6000 r/min.
(3) Proceed with normal operation.
EJU32801Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles behind you.
Use the remote control transmitter to select
the unlock mode. (See page 31 for Yamaha
Security System lock and unlock mode selec-
tion procedures.)
After the watercraft is in the water, start the
engine. Shift into reverse and move the water-
craft back slowly. If there are waves, some-
one should make sure that the watercraft is
not pushed into the trailer before backing
away.
EJU36341Starting the engine
(1) If the lock mode of the Yamaha Security
System is selected, use the remote con-
trol transmitter to select the unlock mode.
(See page 31 for Yamaha Security Sys-
tem lock and unlock mode selection pro-
cedures.)
(2) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep from the bottom of the watercraft.
NOTICE: Never operate in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise
