Engine Compatibility

Designed for Mercury 15 HP and 20 HP carbureted FourStroke outboards. This kit is intended for the carbureted 15/20 HP FourStroke platform and should not be matched by horsepower alone where EFI or later engine variants may require different service parts.

Serial Number Fitment Notice

Oil change kit fitment can vary by engine model, production year, carbureted versus EFI configuration, and serial number. Always confirm 8M0081914 against your Mercury engine serial number, owner’s manual, original oil filter, or parts diagram before ordering.

When This Part Needs Replacement

Use this kit during scheduled oil service, seasonal maintenance, winterization, or any time the engine oil and oil filter are due for replacement. Routine oil changes help reduce internal wear, remove contaminated oil, and protect the engine during both operation and storage.

Installation Notes

Follow the Mercury owner’s manual or service manual for the correct oil change procedure. Warm the engine as directed, drain the old oil safely, replace the oil filter and drain plug seal, refill with the supplied Mercury 25W-40 4-Stroke oil, then run the engine and check carefully for leaks. Recheck oil level after shutdown before returning the outboard to service.
