Mercury Marine Water-Separating Fuel Filter 802893T
The Mercury Marine 802893T is a genuine OEM water-separating fuel filter canister built for remote-mounted Mercury fuel-filter systems. It helps remove water and fuel contaminants before they reach the engine, protecting injectors, carburetors, and fuel pumps from moisture and debris.
Compatible Applications
- Most Mercury outboards
- Mariner outboards
- Mercury MerCruiser sterndrive and inboard engines
- 2-stroke and 4-stroke applications equipped with a compatible remote filter base
Known exclusions include certain 1992 MerCruiser 4.3L Gen II engines with an inline fuel filter, and 1.6L Vazer applications. Always confirm your engine model, serial number, and existing filter number against your owner's manual before ordering, since several Mercury fuel filters share similar spin-on dimensions but different filtration or mounting requirements.

Service Interval
Mercury recommends replacing this filter once per season, or as specified in your engine's owner's manual. Replace sooner if you notice water contamination, restricted fuel flow, corrosion, leakage, or contaminated fuel.
Installation Notes
Shut off the fuel supply and allow the engine to cool before service. Remove the old filter carefully, inspect the sealing surface, and install the new filter according to Mercury service instructions. After installation, prime the fuel system as required and check carefully for leaks before operating the engine.
Technical FAQ
Is this filter the same as the 35-802893T? Yes, 35-802893T is the full Mercury service number for the same part.
Can I use the Quicksilver 802893Q01 instead? Yes, it's the Quicksilver-branded version used in the same remote filter assemblies.
How do I know if my engine uses this filter? If you are unsure whether your remote filter base matches this canister, confirm your engine model and serial number against your owner's manual before ordering.
Parts Desk Insights
Best use case: This filter is best suited to Mercury and Mariner outboards and MerCruiser sterndrive/inboard engines running a remote-mounted water-separating filter setup, where it protects the fuel system from water and debris.
Common mistake: The most common mistake is ordering by spin-on shape alone. Several Mercury filters look identical but have different filtration ratings or mounting threads, so matching by engine model and serial number avoids a mismatch.
Sizing and fitment: This is the filter canister only, for engines already equipped with a compatible remote filter base. If you are unsure your engine has this base installed, check your owner's manual before ordering.
