NOTE:
For installation, reverse the removal proce-

Engine oil level check
1. Check:
Engine oil level
Checking steps:
CAUTION:
When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, or obstacles. The
water current or wind can cause the
watercraft to move and lead to a colli-
sion.
When checking the engine oil level on
land, supply water to the cooling water
passages.
Make sure that engine has enough oil
but do not overfill. If there is too little
oil, the engine can be damaged. If there
is too much oil, the air filter can
become saturated with oil, perma-
nently damaging the filter and reduc-
ing engine performance. Follow the
checking procedure carefully.
Make sure that debris or water does
not enter the oil tank filler hole. Debris
or water in the engine oil can cause
serious engine damage.

5. Remove the air filter element and check it
for dirt and oil. Replace the air filter ele-
ment if there is any oil buildup.
CAUTION:
Do not start the engine with the air filter
case removed, otherwise the engine
could be damaged.
If cleaning the air filter element, use cold
or lukewarm water and let it air dry com-
pletely. Do not use detergent or a solvent
to clean the air filter element, or dry it with
heat or compressed air, otherwise it
could be damaged.
