Tecnoseal X21 Shaft Anode - Zinc - 6" Shaft Diameter

The Tecnoseal X21 Shaft Anode in zinc is designed to protect inboard and outboard marine engines from galvanic corrosion. This essential maintenance tool is particularly beneficial for boaters operating in saltwater and brackish environments, where metal components are at risk of rapid deterioration.

Constructed from pure zinc, the X21 anode sacrifices itself to protect your engine components by corroding preferentially. It mounts directly onto your propeller shaft, providing effective cathodic protection through a galvanic couple with dissimilar metals in the water. Weighing 12.3 lbs, this anode is designed to offer multi-season protection, reducing the need for frequent replacements.

Ideal for cruising anglers and commercial fishing operations, the Tecnoseal X21 is compatible with inboard and shaft-drive outboards. Its robust design ensures that your engine components remain intact, allowing for a longer lifespan of your vessel's powerplant and hull.
