Yamaha - Trim Tab Anode Corrosion Protection & Steering Balance 6E8-45251-02-00. Overview. Trim tab anodes are one of those parts you don't think about until you see corrosion starting to creep in. I've replaced plenty that were completely eaten away, doing exactly what they're supposed to do-protect the rest of the lower unit. This one also helps with steering balance, so it's pulling double duty. Keep it fresh, and you're saving yourself from bigger problems down the line.. Key Features. • Corrosion Protection Design - Sacrificial material helps protect critical lower unit components from damage.• Integrated Trim Tab Function - Assists in balancing steering torque for smoother handling.• Marine-Grade Construction - Built to perform in both freshwater and saltwater environments.• Easy Replacement Fit - Mounts in place of the original anode for straightforward installation.• Exact Yamaha Fitment - Matches factory specifications for proper alignment and protection..
