Engine break-in
NOTICE
ECJ00431
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 56
for information on checking the engine oil
level.)
(2) Launch the watercraft and start the en-
gine. (See page 72 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 30 minutes, operate with the
engine speed below 5000 r/min.
(5) For the next 1 hour, operate with the en-
gine speed below 6000 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.

EJU32333Engine compartment check
WARNING
EWJ00461
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak.
Ventilate the engine compartment. Leave the
engine compartment open for a few minutes
to allow any fuel vapors to escape.
Make sure that there is no damage inside the
engine compartment.
EJU34214Fuel system checks
WARNING
EWJ00381
Leaking fuel can result in fire or explosion.

Check for fuel leakage regularly.

If any fuel leakage is found, the fuel sys-
tem must be repaired by a qualified me-
chanic. Improper repairs can make the
watercraft unsafe to operate.
Make sure that there is no damage, leakage,
or other problem in the fuel system.
Check:

Fuel filler cap and seal for damage

Fuel tank for damage and leakage

Fuel hoses and joints for damage and leak-
age

Fuel tank breather hose for damage and
leakage

Check the fuel level in the fuel tank.
Add fuel if necessary. (See page 54 for infor-
mation on filling the fuel tank.)
EJU32423Water separator check
Make sure that no water has collected in the
water separator. If water has collected in the
water separator, drain it. (See page 31 for in-

tions supplied by the fire extinguisher manu-
facturer. Always keep the fire extinguisher in
the fire extinguisher container.

stalling 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 com-
partment. Make sure that the stern drain
plugs are tightened securely before

EJU40210Riding position
Operator riding position
The operator should grip the handlebars firm-
ly with both hands and sit astride the seat with
both feet on the floor of the footwell.
Passenger riding position
The passenger(s) should hold on firmly, either
to the person in front of them or to the hand-
grip provided, and sit astride the seat with
their feet on the floor of the footwell. Never al-
low a passenger to ride in front of the opera-
tor. (See page 17 for information on the riding
position when pulling a water-skier.)
EJU32802Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles around you.
If the watercraft is launched from a trailer,
someone should make sure that waves do not
push the watercraft into the trailer.
EJU36344Starting the engine on water
WARNING
EWJ01530
Do not apply throttle when anyone is at the
rear of the watercraft. Turn the engine off
or keep it at idle. Water and debris exiting
the jet thrust nozzle can cause severe inju-
ry.
To start the engine:
(1) If the lock mode is selected for the
Yamaha Security System setting, select
the unlock mode. (See page 27 for
Yamaha Security System setting proce-
dures.)
(2) Move the watercraft to an area that is free
from weeds and debris, and has a water
depth of at least 60 cm (2 ft) from the bot-
tom of the watercraft. NOTICE: Never
run the engine in water that is less
than 60 cm (2 ft) deep from the bottom
of the watercraft, otherwise pebbles or
sand could be sucked into the jet in-
take, causing impeller damage and en-
gine overheating.
