When it comes to keeping a high-performance Mercury outboard running strong, the right oil filter makes all the difference. The Mercury 175 to 300 HP V6 & V8 Outboard Oil Filter (35-8M0123025) is designed for engines that demand top-tier protection, delivering cleaner oil and smoother performance even under the toughest marine conditions. Built to handle the rigorous demands of Mercury’s 3.4L V6 and 4.6L V8 FourStroke engines—including the powerful 450 HP Verado—this filter is all about reliability, efficiency, and longevity.

What Makes It Stand Out?

• Precision Filtration – Screens out even the smallest contaminants, keeping oil clean and protecting internal components from premature wear.
• Optimized Oil Flow – Ensures consistent lubrication to critical engine parts, reducing friction and maintaining peak performance.
• Durable Construction – With a metal shell over 50% thicker than standard filters, this unit resists corrosion, making it ideal for saltwater and freshwater applications.

Why It Matters

A high-quality oil filter isn’t just a small piece of routine maintenance—it’s a key component in extending the life of your engine. Replacing it every 100 hours or at least once per season helps prevent costly repairs down the line. Whether you’re pushing wide open throttle offshore or cruising through a quiet lake, this Mercury oil filter keeps your engine running at its best.
