Mercury – Water Separating Fuel Filter | Marine Filtration Series | High-Efficiency Element | 8M0154763

Overview

When you spend real time on the water, you learn quickly that it’s often the smallest parts that make the biggest difference. Fuel is the lifeblood of your engine, and when water sneaks into the system, things can go south fast. That’s why a dependable fuel filter feels less like a maintenance item and more like a quiet guardian sitting between you and an unexpected breakdown. The Quicksilver 8M0154763 Water Separating Fuel Filter delivers that kind of confidence — the kind you notice most when your engine fires up clean, smooth, and ready for another run offshore or across the bay.

Performance & Practical Benefits

You can feel the difference a proper water-separating filter makes, especially when you’re pushing through chop or running at steady cruise for miles at a time. A clean fuel supply means your engine stays responsive, your throttle feels crisp, and you don’t have to wonder whether a surge or stumble is lurking around the next turn.

The 8M0154763 uses a tight 10-micron element to capture contaminants that slip past larger, cheaper filters. More importantly, it strips out water — the quiet enemy that causes corrosion, poor combustion, and long-term engine wear. When your fuel stays dry, you get a smooth idle, steadier acceleration, and a more reliable performance day after day.

Installation is simple, and the filter threads off cleanly when it’s time for annual service or winterization. It’s the kind of maintenance step that feels satisfying because you immediately know you’ve invested in the health of your engine.

Why Buy OEM

If you’ve ever had a trip cut short by engine trouble, you know why OEM matters.

• Built to Mercury Marine’s exacting standards for filtration and flow
• Designed specifically for the demands of marine engines — not adapted from automotive filters
• Offers long-term reliability, especially in humid or salt-rich environments
• Prevents costly damage caused by water intrusion
• Fits correctly, seals properly, and performs the way your engine expects

Aftermarket filters may look similar, but few match the consistency and durability of genuine marine-grade filtration.
