Fuel quality can make or break an engine’s performance, especially out on the water. The Mercury-MerCruiser Water Separating Fuel Filter (35-8M0093688) is built for boaters who demand reliability from their MerCruiser sterndrive and inboard engines. Designed specifically for models from 2004 and newer with Gen III fuel cooler systems, this filter ensures that only clean, contaminant-free fuel makes it to the engine—preventing clogs, misfires, and long-term damage.

What sets this filter apart? Its high-efficiency 15-micron filtration traps impurities before they ever reach the fuel injectors, keeping your engine running at peak power. Built with a rugged blend of polyester, cellulose, and glass fiber, the media stands up to the harshest marine conditions. The added silicon coating enhances durability, so you can count on consistent performance trip after trip.

Why It Matters:

• Superior Filtration – 95% efficient at capturing harmful contaminants, protecting fuel lines and injectors.
• Water Separation – Blocks water and debris, preventing corrosion and fuel system damage.
• Durable Construction – Engineered with high-strength materials to withstand exposure to fuel and moisture.
• Easy Installation – Includes replacement rubber gaskets for a hassle-free swap.

For anyone running a MerCruiser sterndrive or inboard engine, keeping up with fuel filtration isn’t just maintenance—it’s essential protection. Swapping out a worn filter for a fresh one like this ensures optimal fuel flow and long-term engine reliability. Stay ahead of the game and replace yours before fuel quality becomes a problem.
