Quicksilver Water-Separating Fuel Filter 802893Q01 — 25‑Micron OEM Replacement with Gaskets for Mercury/MerCruiser

This replacement unit captures water and particulates before they reach your engine, helping preserve performance and reliability on the water. It fits a wide range of Mercury and MerCruiser applications — including 40–45 hp jet drives, 55–60 hp 3-cylinder outboards, and most sterndrive and inboard engines — and includes the filter element plus rubber gaskets for a correct seal during installation. Quicksilver manufactures this part to meet Mercury Marine original equipment standards, offering proven materials and construction for marine fuel protection.

Which engines and models is this filter compatible with?

This filter is intended for many Mercury and MerCruiser units but has specific exclusions. It is not suitable for 1992 MerCruiser 4.3L Gen II engines equipped with an inline fuel filter, nor for 1.6L Vazer or 3.0L MPI engines. Always cross-reference part numbers and your engine’s service manual before ordering.

• Fits 40–45 hp jet drives and 55–60 hp 3-cylinder outboards
• Compatible with most MerCruiser sterndrive and inboard engines
• Includes replacement filter and rubber gaskets for installation
• Not for 1992 MerCruiser 4.3L Gen II inline-filter models or certain Vazer/MPI engines

How does this filter protect engine performance?

The 25-micron element traps small particles while the water-separating design sheds free water from the fuel stream. Reducing contaminants entering the fuel system helps maintain injector and carburetor function, which supports smoother running and helps prevent power loss or engine damage caused by contaminated fuel.

• 25-micron media captures fine debris that harms fuel components
• Water-separating action removes free water before it reaches the engine
• Material blend (polyester/cellulose/glass fiber) resists breakdown and maintains flow

What materials and specifications make this a reliable OEM replacement?

Quicksilver builds this filter to Mercury Marine original equipment specifications using a layered filter media and a phenolic binder coated with silicon for durability. The construction balances filtration efficiency with consistent fuel flow, and the part undergoes marine-grade testing to withstand the corrosive, vibration-heavy marine environment.

• Polyester/cellulose/glass fiber media with phenolic binder
• Silicon coating improves media durability and moisture resistance
• Produced to Mercury Marine OEM standards for fit and function

How do I install and maintain the replacement filter?

Installation is straightforward when you follow the engine manufacturer’s service instructions: drain fuel pressure if required, replace the filter element, install the supplied rubber gaskets, and check for leaks. Routine inspection and periodic replacement prevent clogging and water accumulation in fuel systems — an inexpensive maintenance step that helps avoid costly repairs.

• Use the included rubber gaskets for a proper seal
• Follow torque and installation steps in your engine manual
• Inspect and replace per season or manufacturer interval, or sooner if contaminated fuel is suspected
