Engine Compatibility
This filter is widely listed for most Mercury outboards and MerCruiser engines using a remote-mounted water-separating fuel filter setup. Dealer fitment notes also call out exceptions, including certain 1992 MerCruiser 4.3L Gen II engines with an in-line fuel filter, 1.6L Vazer engines, and some references also exclude 3.0L MPI applications, so exact fitment should always be confirmed by engine model and serial number before ordering.
Serial Number Fitment Notice
Please confirm compatibility by your exact Mercury or MerCruiser serial number and by verifying that your engine uses a remote-mount water-separating fuel filter system. That matters more than appearance alone on fuel-system parts.
When This Part Needs Replacement
Replace this filter during routine fuel-system service, at least once each season, or whenever contaminated fuel or water intrusion is suspected. Water-separating filters help protect engine efficiency and fuel economy by removing water and fuel-borne contaminants before they reach the engine.
Installation Notes
This is the filter canister only for compatible remote-mount systems. Install only on applications that call for 802893T / 35-802893T, and service it at the interval recommended in the owner’s manual.

Parts Desk Insight
On MerCruiser fuel systems, a water-separating filter is one of the simplest maintenance parts that can prevent much bigger problems. Keeping a fresh filter on the engine is a smart move anytime you are dealing with seasonal storage, unknown fuel quality, or a boat that sits for stretches. This is a practical service inference supported by Mercury’s emphasis on water removal and regular replacement.
