EJU32400Engine oil level
Check the engine oil level before each use.
CAUTION:
ECJ00390
When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and 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. (See page 66 for procedures
on supplying water.)
Make sure that the engine has enough
oil, but do not overfill it. If there is too lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter can be-
come saturated with oil, permanently
damaging the filter and reducing engine
performance. Follow the checking pro-
cedure carefully.
Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
To check the engine oil level:
(1) Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.
