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. Level Ground [A]

•Remove the dipstick [A], wipe it dry and insert it back to the dipstick tube [B], and then remove it again to check the oil level.
