Pre-operation check pointsEJU42384Pre-launch checks
Perform the pre-launch checks in the pre-op-
eration checklist while the watercraft is on
land.
To perform the pre-launch checks:
(1) Remove the seats and removable water-tight storage compartment. (See page 69
for seat removal and installation proce-
dures and page 75 for information on the
removable watertight storage compart-
ment.)
(2) Perform the checks and make sure that there are no malfunctioning items or oth-
er problems.
(3) After completing these checks, securely install the removable watertight storage
compartment and seats in their original
positions.
EJU32334Engine compartment checkEWJ00462
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.
EJU34215Fuel system checksEWJ00382
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 77 for infor-
mation on filling the fuel tank.)
EJU32424Water 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 28 for in-
formation on draining the water separator.)
