Serial Number Fitment Notice

Service kit fitment can vary by horsepower, engine family, model year, and serial number. Always confirm 8M0097854 against your engine serial number, Mercury parts diagram, or owner’s manual before ordering.

When This Part Needs Replacement

Use this kit during the scheduled 100-hour service interval, seasonal maintenance, or when replacing the oil filter, in-line fuel filter, and gearcase drain seal components as part of routine outboard service. Fresh filters and drain seals help maintain clean oil, clean fuel delivery, and proper sealing at serviced drain points.

Installation Notes

Follow the Mercury owner’s manual or service manual for the correct 100-hour maintenance procedure. This kit includes the service parts, but Mercury 4-Stroke oil and Mercury gear lube are sold separately. After service, check for leaks, verify oil and gearcase fluid levels, and confirm proper engine operation before returning the outboard to use.

Parts Desk Insight

This kit is built specifically around the 2.1L Mercury 75–115 HP FourStroke platform, so serial number is the key check. It is a convenient kit when the engine is due for 100-hour service, but oil and gear lube still need to be ordered separately to complete the maintenance.
