About This Part
Mercury 8M0082911 is a genuine OEM air filter for Mercury 1.7L EFI FourStroke outboards in the 75–115 HP range. The air filter is a critical component of the engine’s fuel injection system — it prevents airborne contaminants from entering the throttle body and combustion chambers, protecting injectors, throttle plates, and internal engine components from abrasive wear. A clogged or deteriorated air filter restricts airflow, reduces fuel efficiency, and can cause rough running or hard starting on EFI engines. Replacing it with a genuine OEM filter ensures the correct fit, filtration rating, and airflow characteristics for this engine family.
Compatible Applications
Designed specifically for the Mercury 1.7L (1731cc) EFI FourStroke platform. Always confirm fitment using your engine serial number before ordering — other Mercury 75–115 HP platforms use different air filter assemblies.

Serial Number & Fitment Notice

Part Number Reference
- Current Part Number: 8M0082911
- Mercury Reference: 35-8M0082911
Service Interval
Mercury recommends inspecting the air filter annually or every 100 hours of operation, whichever comes first. Replace the filter whenever it shows visible contamination, restriction, or damage, or as part of a scheduled annual service. Operating in dusty or high-particulate environments may require more frequent replacement.
When to Replace
Replace the air filter when the engine shows any of the following:
- Rough idle or hesitation under load
- Reduced fuel efficiency
- Hard starting on an otherwise well-maintained engine
- Visible contamination, oil saturation, or physical damage to the filter element
- Annual service interval reached
Installation Notes
Ensure the air filter housing and sealing surfaces are clean before installing the new filter. Confirm the filter seats fully and the housing cover is properly secured before starting the engine. Do not run the engine without the air filter installed.

Parts Desk Insights
Best Use Case: This air filter is the correct choice for annual service or a 100-hour service on a 1.7L Mercury EFI FourStroke in the 75–115 HP range. It pairs well with a fuel filter replacement and spark plug service for a complete annual tune-up on this engine family. Customers doing a full service should also inspect the throttle body for carbon buildup while the air filter housing is open — it’s easy access and worth checking at the same time.
Common Issues: The most frequent problem is ordering an air filter by horsepower alone without confirming the engine displacement and serial number. Mercury has produced multiple 75–115 HP FourStroke platforms over the years, and the air filter assemblies are not interchangeable between platforms. The 1.7L (1731cc) EFI platform covered by this filter has a specific serial number range — engines outside that range require a different part. Always confirm using the serial number before ordering.
