Tecnoseal Magnesium Hull Plate Anode 8-3/8" x 4-1/32" x 1-1/16" – TEC-Z-406MG

The Tecnoseal TEC-Z-406MG Magnesium Hull Plate Anode is designed to provide superior cathodic protection for boats operating in freshwater environments. Manufactured from high-grade magnesium, this hull-mounted sacrificial anode helps prevent galvanic corrosion by protecting underwater metal components such as shafts, struts, trim tabs, rudders, and through-hulls.

Measuring 8-3/8" x 4-1/32" x 1-1/16", this plate-style anode offers substantial surface area for long-lasting performance. It mounts directly to the hull, where it sacrifices itself to protect more valuable underwater metals, helping extend the life of critical components.

• Freshwater Specialized: Magnesium is intended strictly for freshwater. If used in salt or brackish water, it will "over-protect" and dissolve far too quickly, potentially damaging your paint or metal.

• High-Quality Italian Casting: Tecnoseal is one of the world's leading manufacturers of marine cathodic protection, ensuring high purity and consistent performance.

• Standard Size: The 8-3/8" length is a common "mid-size" plate, providing significant surface area for protection without excessive drag.

• Easy Installation: Features two mounting holes for secure attachment to the hull’s bonding system.

Why Choose Magnesium?

Magnesium anodes are specifically recommended for freshwater use because they provide stronger protective current in low-conductivity water. Using zinc in freshwater can lead to under-protection, while magnesium ensures optimal corrosion prevention.

⚠️ Not recommended for saltwater use.

In The Box

• 1 x Tecnoseal Magnesium Hull Plate Anode

• Note: Mounting hardware (bolts/nuts) is typically not included, as it must be matched to your specific hull thickness and material.

Maintenance & Safety

• Don't Paint It: Never paint the surface of an anode. It must have direct contact with the water to function.

• Check the 50% Rule: Replace the anode when it has dissolved to roughly 50% of its original size.

• Clean the Contact Point: Ensure the area where the anode meets the mounting bolt is clean and free of corrosion or paint to maintain electrical continuity.

Ideal Applications

• Freshwater boats and pontoons

• Ski and wake boats

• Fishing boats

• Houseboats

• Inland marina vessels

• Freshwater trim tab and shaft protection
