High-flow replacement air filter compatible with Mercury 75–115 HP 4-stroke outboards, built to match OEM fit and filtration specs.

This ETTE air filter from JUSTSWAGDDEEFF is a direct-fit replacement for Mercury part numbers 35-897575T01, 35-897575T02 and 35-8M0082911, engineered for Mercruiser EFI 75, 80, 90, 100 and 115 horsepower 4-stroke engines. It’s manufactured from durable filter media and housing materials to restore proper airflow and engine protection after the original filter reaches end of life. The unit is sized and shaped to mate with standard Mercury airbox assemblies so installation is straightforward for DIYers and marine technicians alike.

Will this filter fit my Mercury 75–115 HP EFI 4-stroke engine?

Yes — this ETTE unit replaces the Mercury OEM numbers listed and is intended for Mercruiser 75, 80, 90, 100 and 115 HP EFI 4-stroke applications. Verify the part number on your existing filter or consult your engine’s parts manual if you’re unsure.

• Replaces Mercury part numbers: 35-897575T01, 35-897575T02, 35-8M0082911
• Compatible with Mercruiser 75–115 HP EFI 4-stroke models
• Form, fit and mounting points match OEM dimensions

How does this replacement maintain engine performance?

By restoring the designed airflow path and trapping airborne particulates, the filter helps the engine breathe as intended and reduces contaminant entry to intake components. Cleaner air supports smoother fuel combustion and helps protect injectors and sensors from premature wear.

• Media designed to capture dust and debris while allowing sufficient airflow
• Rigid frame preserves sealing surface to prevent unfiltered bypass
• Helps maintain stable EFI operation under normal boating conditions

Is installation straightforward and what should I check during replacement?

Installation is typically quick: remove the airbox cover, swap out the old filter, and reseal the cover to the manufacturer torque or clip spec. Inspect seals and the airbox interior for oil, water, or heavy deposits and replace any damaged gaskets to ensure a good seal.

• Tools: usually none or basic hand tools depending on engine model
• Check airbox gasket and mounting clips for wear
• Replace at recommended service intervals or when visibly soiled

What materials and part numbers does this filter use?

The filter combines engineered media with a durable housing to match factory part characteristics, and the listing explicitly covers the Mercury OEM numbers it replaces. Buying the correct part number helps avoid fitment issues and keeps maintenance records consistent.

• Manufacturer references: 35-897575T01, 897575T01, 35-897575T02, 897575T02, 35-8M0082911, 8M0082911
