Checking the Engine's Lubricating Oil
1. Check for any engine oil leakage. Should an oil leak be detected, inspect the engine to locate the leak
and correct it. Tightening of fittings and bolts is considered normal maintenance and is the responsibility
of the owner.
2. Check engine's oil level with the oil dipstick at least once daily prior to engine usage. Add oil as needed.
3. Make sure the engine's oil level is maintained near, but not over, the F mark on the dipstick. If the engine's
oil drops close to the L mark, add the engine oil until the oil level reaches the F mark. Keep an eye on the
engine's oil level. After the engine is broken in, if the engine continues to consume a noticeable quantity
of engine oil, consult a competent marine mechanic.
NOTE: Maintaining the engine's oil level with the proper lubricating oil, and making sure that
the oil is changed at the proper intervals, is the responsibility of the owner/operator. Engine
damage resulting from the lack of engine oil, from the wrong type of oil, or from unclean oil is
not a warrantable issue.
