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.
CAUTION:
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU36140Engine break-in
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.
CAUTION:
ECJ00440
Be sure to check the engine oil level be-
fore operating the watercraft for the first
time. (See page 53 for engine oil checking
procedures.)
(1) Launch the watercraft and start the en-
gine. (See page 61 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 8000 r/min.
(3) Proceed with normal operation.
CAUTION:
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
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 33 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.
EJU36340Starting the engine
WARNING
EWJ00560
Never start the engine or let it run for any
length of time in an enclosed area. Ex-
haust fumes contain carbon monoxide, a
colorless, odorless gas that may cause
loss of consciousness and death within a
short time. Always operate the watercraft
in an open area.

To replenish the battery:
(1) Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
(2) Refill the battery with distilled water if
necessary.
CAUTION:
ECJ00240
Normal tap water contains minerals that
are harmful to a battery. Use only distilled
water for replenishing the battery.
To recharge the battery:
CAUTION:
ECJ00250
Do not attempt to charge a battery hastily.

It is recommended to have a Yamaha dealer
charge the battery. If you charge the battery
yourself, carefully read the battery charger in-
structions before charging and follow the
points below.
(1) Remove all of the battery caps.
(2) If the electrolyte level is low, add distilled
