Quicksilver Water-Separating Fuel Filter 802893Q01 for Mercury & MerCruiser — 25‑micron cartridge with gaskets

Quicksilver 802893Q01 is a water-separating replacement fuel filter designed to trap water and fuel contaminants to help protect Mercury and MerCruiser outboards and sterndrives.

This OEM-quality replacement fuel filter fits a range of Mercury outboards (including 40–45 hp Jet and 55–60 hp 3-cylinder models) and most MerCruiser sterndrive and inboard engines, excluding 1992 MerCruiser 4.3L Gen II inline-filtered engines and certain Vazer and MPI models. Engineered to Mercury Marine specifications, the cartridge uses a multi-fiber media to capture particles down to 25 microns and separate moisture from gasoline, and it ships with the rubber gaskets required for installation.

How does this filter protect my engine on the water?

The 802893Q01 captures solid contaminants and sheds entrained water before fuel reaches the carburetor or injectors. Removing these impurities reduces the risk of clogged jets, rough idling, and premature wear in fuel-system components. Because it meets OEM specs, fitment is reliable and performance remains consistent under marine conditions.

• 25-micron filtering element removes damaging particulates
• Water-separating design helps prevent corrosion and misfires
• OEM manufacturing ensures correct fit and sealing

What materials and construction make this filter effective?

The cartridge combines polyester, cellulose, and glass fibers bound with phenolic resin and coated with silicon for strength and fuel resistance. This layered media traps a range of particle sizes while maintaining flow to avoid starvation under load. The included rubber gaskets complete the seal to prevent bypass and maintain proper pressure in the fuel line.

• Multi-fiber media for balanced filtration and flow
• Phenolic binder and silicon coating increase durability
• Includes new rubber gaskets for a leak-free install

Which engines and models are compatible with this replacement filter?

This Quicksilver element is compatible with many Mercury and Mariner outboards and most MerCruiser sterndrive/inboard engines, specifically common 40–60 hp outboards and a broad range of sterndrive applications. It is not intended for 1992 MerCruiser 4.3L Gen II engines that use an inline filter, nor for 1.6L Vazer and 3.0L MPI engines. Always verify part cross-reference numbers and engine application before ordering.

• Fits 40–45 hp Jet and 55–60 hp 3-cylinder outboards
• Suitable for most MerCruiser sterndrive and inboard engines
• Not compatible with 1992 MerCruiser 4.3L Gen II inline-filter models, 1.6L Vazer, or 3.0L MPI engines

How simple is installation and maintenance?

Installation is straightforward for anyone familiar with routine marine maintenance: drain fuel pressure, remove the old cartridge, replace gaskets, and install the new filter. Regular replacement intervals depend on fuel quality and hours of operation—inspect during seasonal service or if you notice fuel delivery issues. Keeping a fresh Quicksilver filter on hand reduces downtime and helps maintain smooth operation.

• Includes replacement rubber gaskets for immediate installation
• Quick cartridge swap with basic hand tools
• Inspect during seasonal service or when fuel problems appear

Who is this for? The Quicksilver 802893Q01 is aimed at boat owners, mariners, and technicians who want an OEM-grade fuel filter that matches Mercury Marine standards. It's ideal for operators of compatible outboards and MerCruiser sterndrives who prioritize reliable fuel delivery, reduced contamination-related wear, and an easy, correct fit backed by a brand with decades of marine parts experience.
