Serial Number Fitment Notice
Oil filter fitment can vary by engine model, production range, filter mount, and original part number. Always confirm 861475 / 21549544 against your Volvo Penta engine serial number, original filter, or parts diagram before ordering.
When This Part Needs Replacement
Replace the oil filter during scheduled oil changes, seasonal maintenance, winterization, or any time the filter is overdue, damaged, leaking, corroded, or contaminated. A fresh oil filter helps reduce abrasive contamination in the lubrication system and supports longer engine life.
Installation Notes
Install according to the Volvo Penta service manual for the specific engine. Clean the sealing surface, lightly oil the new filter gasket, thread the filter onto the original filter mount by hand, and tighten as specified. After refilling the engine with the correct oil, run the engine, check for leaks, shut down, and recheck the oil level before returning the engine to service.
