Tecnoseal

Protect your metal from corrosion

Galvanic corrosion silently eats the underwater metal on a boat, and sacrificial anodes are the defense, with Tecnoseal a leading maker. An anode is a piece of less-noble metal that corrodes in place of your engine, drive, shaft, propeller, and running gear, sacrificing itself to protect the expensive components. Tecnoseal makes zinc, aluminum, and magnesium anodes in the shapes and fittings for outboards, sterndrives, shafts, hulls, and more. By replacing worn anodes before they are used up, you keep your boat's metal protected. For boaters, the right Tecnoseal anodes are cheap insurance against costly corrosion damage.

Choosing the right anode comes down to material and fit, and your water. Use zinc for salt water, aluminum for salt or brackish water and many newer applications, and magnesium for fresh water, since using the wrong material for your water reduces protection. Match the anode shape and size to the specific part it protects, your engine, drive, shaft, or hull, since they are part-specific. Replace anodes when about half consumed. Review the product details and your water type before buying. With Tecnoseal anodes, you protect your boat's metal from corrosion.
