About This Kit

Mercury 8M0081917 is a genuine OEM oil change kit designed for Mercury 1.7L EFI FourStroke outboards in the 75–115 HP range. It includes everything needed for a complete engine oil service — the correct volume of marine-specific 25W-40 oil, a premium oil filter, and a drain plug seal — so you have all the right parts before starting the job. The included oil is formulated with corrosion inhibitors for on-water use and off-season storage protection, and is engineered to maintain viscosity under the high-temperature, high-rpm demands of marine operation.

Kit Contents

  • 5 litres Mercury SAE 25W-40 4-Stroke Marine Engine Oil
  • Mercury premium oil filter
  • Drain plug seal
  • Service instructions

Compatible Applications

Designed for Mercury 1.7L EFI FourStroke outboards. Confirm fitment using your engine serial number — later Mercury 75–115 HP platforms use different service parts and this kit should not be selected by horsepower alone.

  • Mercury 75 HP EFI FourStroke (1.7L) — serial range 1B366823 through 2B094995
  • Mercury 90 HP EFI FourStroke (1.7L) — serial range 1B366823 through 2B094995
  • Mercury 115 HP EFI FourStroke (1.7L) — serial range 1B366823 through 2B094995

Serial Number & Fitment Notice

This kit is specific to the older 1.7L EFI FourStroke platform within the serial number range above. Mercury 75–115 HP outboards produced outside this range may use a different oil change kit. Always confirm 8M0081917 against your engine serial number, owner's manual, or the Mercury parts catalog before ordering.

Service Interval

Mercury recommends changing the engine oil and filter every 100 hours or annually, whichever comes first. This kit is also appropriate for seasonal maintenance, winterization, or any time the oil and filter are due for replacement. Regular oil changes remove contaminated oil, reduce internal wear, and protect the engine during both active use and storage.

Installation Notes

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

Parts Desk Insights

Best Use Case: This is the right kit for a full oil change on a 1.7L Mercury EFI FourStroke in the 75–115 HP range. The 5L volume is sized correctly for this engine family, and having the filter and drain seal included means the job can be completed without a separate parts run. It's a strong choice for spring commissioning and fall winterization, and works equally well for shop service or owner-performed maintenance.

Common Mistakes: The most frequent error is selecting this kit based on horsepower alone. Mercury has produced multiple 75–115 HP FourStroke platforms over the years, and later engines use different oil change kits. The serial number range (1B366823–2B094995) is the definitive check — if the engine serial falls outside that range, a different kit is required. A second common mistake is skipping the drain plug seal replacement. The old seal compresses over time and can weep oil if reused; the new seal is included in this kit and should always be installed.
