Stop letting water ruin perfectly good fuel. Mercury’s Fuel / Water-Separating Filter 8M0157616 snaps into the “castle” bowl on every L-6 Verado, Gen-5 200–300 hp FourStroke, and V-10 platform, stripping out moisture and grit long before they reach the rail. The latest redesign is shorter and easier to grip, yet it holds the same volume as the original canister—so swaps stay quick and clean, even in a crowded bilge.

Why this OEM cartridge earns a spot in your 100-hour kit

• Premium 10-micron media—over 90 % efficiency at trapping fine debris without starving the high-pressure pump.

• Built-in water trap & drain meets U.S. Coast Guard and ABYC H-24 specs when paired with the optional water-in-fuel sensor (8M0157779).

• Reinforced nylon end-caps shrug off 90 psi and 220 °F hot-soak temps.

• Includes new O-ring for the sensor port—no hunting for extra parts.

Twist out the old can, click this one home, prime the bulb, and head for open water. You’ll feel cleaner starts, steadier mid-range pull, and the confidence that every gallon of 87 octane is hitting your injectors water-free—exactly the way Mercury engineers planned it.
