PERIODIC MAINTENANCE SCHEDULE
Daily and periodic maintenance is important to keep the engine in good operating condition. The following
is a summary of maintenance items by periodic maintenance intervals. Periodic maintenance intervals vary
depending on engine application, loads, diesel fuel and engine oil used and are hard to establish
definitively. The following should be treated only as a general guideline.
Establish a periodic maintenance plan according to the engine application and make sure to perform the
required periodic maintenance at the intervals indicated. Failure to follow these guidelines will impair the
engine’s safety and performance characteristics, shorten the engine’s life and may affect the warranty
coverage on your engine. Contact your authorized Yanmar Marine dealer or distributor for assistance when
checking items marked with a ●.
