Performance & Practical Benefits

A trim tab anode does more than fight corrosion—it can influence how your boat handles, tracks, and responds under load. The 98432T6 provides a secure, snug fit that keeps torque feedback in check while protecting vulnerable metal surfaces.

Real-world benefits include:

• Strong corrosion resistance that shields your gearcase from costly damage
• A steady, predictable steering feel, especially when balancing prop torque
• Smooth, stable running, even in chop or tight maneuvering
• Zinc construction optimized for both fresh and saltwater conditions
• Quick, straightforward maintenance—just inspect periodically and replace at the first signs of heavy pitting

If you’ve ever felt your steering start to wander or seen early signs of corrosion creeping in, upgrading or replacing your anode can make an immediate difference.

Why Buy OEM

There’s a reason seasoned boaters stick with Mercury OEM parts:

• Exact fit, engineered for your specific outboard
• Reliable corrosion behavior, unlike off-brand anodes that can wear unevenly
• Long-term protection, saving you from expensive lower-unit repairs
• Designed, tested, and manufactured with Mercury’s proven marine standards
• Cost-effective maintenance that preserves your investment

You’re not just buying zinc—you’re buying peace of mind each time the boat leaves the dock.
