Mercury – Aluminum Power Trim Anode | Corrosion Protection Series | Aluminum | 8M0217561

Overview

When you run a powerful Mercury Verado or Mercury Racing outboard, you’re trusting that engine to carry you through long channels, steep chop and those glassy early-morning runs that remind you why you love boating. But all that time in the water also means constant exposure to corrosion—something you can’t see day to day but always need to stay ahead of. That’s where the Mercury Aluminum Anode 8M0217561 steps in. It provides that steady reassurance that your trim system is protected, letting you focus on the water instead of what’s happening beneath it.

Performance & Practical Benefits

Corrosion protection doesn’t always get the spotlight, but it plays a massive role in how your engine ages, how smoothly your trim system operates and how confidently you can push your boat. This aluminum anode performs with a steady, predictable wear pattern, creating a strong barrier that absorbs corrosive activity so your high-horsepower outboard doesn’t have to.

You’ll appreciate how cleanly and tightly it fits. There’s no forcing, no guesswork—just a smooth, secure seat that aligns exactly as Mercury intended. Once in place, it works continuously, even when the boat sits moored for long periods. Whether you’re running saltwater coastlines or inland lakes, this anode gives your engine the balanced protection it needs.

Why Buy OEM

When you choose a genuine Mercury Marine part number, you’re choosing a component engineered to protect a serious investment. Aftermarket anodes often use generic alloy mixes that don’t match Mercury’s electrical load requirements—and that can lead to premature wear or uneven corrosion.

This OEM anode is built to Mercury’s exact standards, creating the right chemical balance for your trim system and helping all surrounding components last longer. It’s a choice experienced boaters make not because it’s flashy, but because it works—and keeps working.
