WARNING
Watercraft operation with insufficient, deteriorated,
or contaminated engine oil will cause accelerated
wear and may result in engine seizure, accident,
and injury.
Oil Level Inspection
This watercraft engine is equipped with a semi-dry sump.
In the semi-dry sump engine, the oil level difference is very
large between the level measured after just stopping and
that after leaving for a long time.
It is necessary to check the specified amount of oil is in
the engine before starting the engine every day. At this
time use the cold mark of the level gauge. Then run the
engine to lubricate the engine parts sufficiently. After that
it is necessary to check the level by using hot mark of the
level gauge.
Preliminary Check
•
Remove the seat (see Hull/Engine Hood chapter).
•
Whenever checking the engine oil level, keep the water-
craft level side to side and fore to aft as much as possible.

the dipstick tube [B], and then remove it again to check
the oil level.

level lines on the dipstick [C] (Use level lines when engine
is cold).
