Maintenance

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.
