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.
EJU32750Engine 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:
ECJ00420

For the first 5 hours of operation or 2
tankfuls of fuel, premix the fuel in a fuel-
to-oil ratio of 25:1.

After break-in, premix the fuel in a fuel-
to-oil ratio of 50:1 for normal operation.
(1) Launch the watercraft, start the engine,
and then board the watercraft. (See page
33 for engine starting procedures.)
(2) Run the engine at the lowest possible
speed for 5 minutes.
(3) Gradually apply throttle to 3/4 or less.
(4) Operate the watercraft at 3/4 throttle or
less for the first tankful of fuel.
(5) Fill the fuel tank once more with fuel in a
fuel-to-oil ratio of 25:1, and then 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.
EJU32820Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles around you.
After the watercraft is in the water, turn it
around so that the bow faces the direction you
wish to go. Start the engine, and then slowly
move away from the launching area. If there
are waves, someone should make sure that
the watercraft is not pushed into the trailer af-
ter launching the watercraft.
EJU32830Starting 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.
(1) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep.
