Mercury – On-Engine Water Separating Fuel Filter | V6/V8 FourStroke Series | Composite Filtration | 8M0176313

Overview

Every boater has a moment when they realize just how much they depend on clean, steady fuel. Maybe it happens on a long run back through choppy water, or while idling into a quiet marina at sunset. When your engine breathes clean fuel, everything feels smoother — the throttle responds the way it should, the boat settles into its rhythm, and you can relax knowing your powerplant is being taken care of. The Quicksilver 8M0176313 Water Separating Fuel Filter is one of those small, behind-the-scenes parts that quietly protects your day on the water. It’s dependable, it’s proven, and it’s the kind of component you don’t think about until you’re glad it’s there.

Performance & Practical Benefits

A clean fuel system isn’t just about performance — it’s about trust. With this filter in place, you’ll feel the engine run smoother at idle and more responsive when you push the throttle. The 10-micron filtration level captures the fine particles that can slip past older or aftermarket filters, helping prevent the hesitation and power loss that dirty fuel can cause.

Water separation is equally important, especially for boats that spend time stored, refueled at marinas, or exposed to humidity. By trapping water before it reaches high-pressure components, the filter helps extend engine life and maintains efficiency on long-haul days. Replacement is quick and clean — a simple, straightforward maintenance step most boaters can do themselves with basic tools.

Why Buy OEM

OEM filtration is engineered specifically for Mercury’s fuel systems, which means everything — flow rate, pressure, and internal media — matches what the engine was designed to use. Aftermarket filters may “fit,” but they often miss the details that matter most: proper micron levels, consistent construction, and valves that won’t fail under marine vibration.

Choosing a Mercury Marine part ensures reliable protection, fewer fuel-system issues, and long-term performance that keeps the engine running the way it was meant to. If you want reliability without guesswork, OEM is the smart call.
