iFJF Fuel/Water Separator Kit 10-Micron — Replacement for Mercury, 90 GPH Spin-On Filter

This replacement kit delivers reliable filtration for inboard, sterndrive and outboard fuel-injection systems that require a 10-micron element. Engineered to flow up to 90 gallons per hour, the kit balances high contaminant capture with the fuel demand of modern marine engines. It replaces multiple Mercury part numbers, offering an affordable option for routine maintenance and improved fuel-system longevity.

How does this separator protect my engine on the water?

The iFJF kit traps water and particles that can damage injectors, carburetors and other fuel-system components. By removing contaminants down to 10 microns with over 90% efficiency, it lowers the risk of clogs and premature wear without restricting normal fuel flow.

• 10-micron filtration removes fine particles and entrained water droplets.
• Maintains up to 90 GPH flow to meet high-demand engines.
• Reduces injector fouling and fuel-line corrosion risk.

Which Mercury parts does this replace and is installation straightforward?

This kit is compatible with several Mercury part numbers so it fits many common service intervals. Installation is typical for spin-on separators; the filter must be tightened by hand during installation to ensure a proper seal and avoid leaks.

• Replaces: Mercury 35-807172, 35-60494-1, 35-802893Q01 and others.
• Standard spin-on fitment for quick swap-outs during maintenance.
• User must hand-tighten the filter when installing to secure the seal.

Will this filter starve my engine of fuel at high rpm?

No — the element is sized to support heavy fuel demand while offering effective contaminant capture. With a flow rating of 90 GPH, it feeds most marine motors without compromising performance under load.

• 90 GPH flow rating supports high-consumption engines.
• 10-micron efficiency without excessive restriction.
• Suitable for inboards, sterndrives and outboards with fuel injection systems.

What maintenance schedule should I follow for best results?

Inspect the separator at each service interval and replace the element when contaminated or per manufacturer recommendations. Regular checks after winter storage or heavy sediment exposure will keep the fuel system operating reliably.

• Check during routine service or at manufacturer-specified intervals.
• Replace if you detect water, strong fuel odors, or performance issues.
• Keep a spare filter on board for quick swaps during boating season.

Who is this for: The iFJF 802893Q01 kit is intended for boat owners, marine mechanics and fleet operators who need a dependable, direct-fit replacement for Mercury fuel-water separators. It suits anyone running fuel-injected inboard, sterndrive or outboard systems who wants a balance of fine filtration and high flow to protect fuel components and maintain engine performance.
