EJU32281
Pre-operation check points EJU40684Pre-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 hood. (See page 22 for hood
removal and installation procedures.)
(2) Perform the checks and make sure that
there are no malfunctioning items or oth-
er problems.
(3) After completing these checks, install the
hood in its original position.
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.
EJU34206Fuel 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:

Carburetor for leakage

Fuel filler cap and seal for damage

Fuel in fuel tank for water and dirt

Fuel tank for damage and leakage

Fuel hoses and joints for damage and leak-
age

Fuel filter for leakage

Fuel cock for leakage

Fuel tank breather hose for damage and
leakage
Releasing the pressure in the fuel tank
Release the pressure in the fuel tank before
each use.
To release the pressure in the fuel tank:
(1) Loosen the fuel filler cap slowly and re-
move it to release any pressure in the fuel
tank.
(2) Install the fuel filler cap and tighten it se-
curely.
EJU32363Fuel level check
Check the fuel level in the fuel tank.

EJU41180Lubrication points
Lubricate moving parts with water-resistant
grease. (See page 53 for information on the
main lubrication points.)
Intermediate housing
Fill the intermediate housing with water-resis-
tant grease through the grease nipple using a
grease gun.
EJU34225Checking the fuel filter
Check the fuel filter. The fuel filter should be
replaced if water or dirt is found in the filter.Have a Yamaha dealer replace the fuel filter if
necessary.
EJU34377Checking the spark plugs
WARNING
EWJ00350
Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks to
escape, which could result in a fire or ex-
plosion.
Remove and check the condition of the spark
plugs.
The condition of a spark plug can indicate
something about the condition of the engine.
For example, if the center electrode portion is
very white, this could indicate an intake air
leak or carburetion problem in that cylinder.
Do not attempt to diagnose any problems
yourself. Have a Yamaha dealer service the
watercraft.
