When it comes to marine engines, fuel quality isn’t something to take lightly. Even the smallest contaminants can wreak havoc on performance, leading to clogged injectors, reduced efficiency, and costly repairs. The Mercury-MerCruiser 35-8M0204703 Water Separating Fuel Filter Disc is designed to keep fuel clean, ensuring smooth and reliable operation for 2004 and newer Mercury/MerCruiser sterndrive and inboard engines equipped with Gen III Cool Fuel Systems.

This filter disc effectively removes water and debris before they can enter the fuel system, preventing corrosion and premature wear. Its high-quality construction meets Mercury Marine’s original equipment specifications, making it a direct replacement that fits precisely and performs reliably. Built to withstand the harsh marine environment, it helps maintain optimal fuel flow and engine efficiency.

Why It Matters:

• Protects the Fuel System – Captures water and contaminants, preventing engine damage and performance loss.
• Built for Marine Conditions – Durable construction holds up in demanding environments.
• Optimized for Mercury/MerCruiser Engines – Ensures proper fit and function for sterndrive and inboard models with Gen III Cool Fuel Systems.
• Essential Maintenance – A simple replacement that helps extend engine life and keep performance consistent.

A clean fuel system is key to avoiding headaches on the water. Replacing this filter regularly keeps the engine running smoothly, reduces the risk of fuel-related issues, and ensures you're getting the most out of every drop of fuel.
