Tecnoseal X3MG Shaft Anode - Magnesium - 1" Shaft Diameter

The Tecnoseal X3MG Shaft Anode in magnesium is a sacrificial corrosion-control component designed to protect your boat's propeller shaft from galvanic corrosion and pitting. This anode is essential for boaters operating in freshwater and mixed-salinity environments, where bare metal is particularly vulnerable to corrosion. It intercepts electrochemical attacks, ensuring your shaft remains intact and functional.

Sized for 1-inch shaft diameters, the Tecnoseal X3MG employs a proven magnesium alloy that corrodes preferentially instead of your steel shaft, bronze bearings, or stainless fasteners. This design allows for effective corrosion protection, as magnesium anodes establish a more negative galvanic potential than zinc, making them ideal for freshwater applications. The compact design of the anode, measuring 2 x 2 x 2 inches, facilitates straightforward installation and replacement, even in tight spaces.

Boaters with inboard and inboard-outboard engines will find the Tecnoseal X3MG essential for maintaining reliability season after season. Regular inspection and replacement of the anode, typically on an annual basis in hard-use conditions, ensures ongoing protection without maintenance headaches. Whether navigating coastal bays, rivers, or lakes, this anode fits standard shaft mounts, providing peace of mind for your propulsion system.
