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 50
for information on checking the engine oil
level.)
(2) Launch the watercraft and start the en-
gine. (See page 66 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.

ment and seats in their original positions.
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 48 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 30 for in-
formation on draining the water separator.)
