Tecnoseal X13AL Shaft Anode - Aluminum - 3" Shaft Diameter

The Tecnoseal X13AL Shaft Anode is essential sacrificial protection for any boat owner running an inboard or outboard engine with a 3-inch shaft diameter. This aluminum anode is designed to combat the corrosive effects of saltwater and brackish environments, which can significantly deteriorate metal components over time.

Constructed from pure aluminum alloy, the X13AL anode oxidizes preferentially to steel and bronze components in galvanic couples, effectively preventing galvanic corrosion. As the anode corrodes, it protects critical drivetrain hardware from pitting and structural weakening, ensuring the longevity of your boat's engine components.

Both freshwater and saltwater anglers, cruisers, and commercial operators will find value in this anode's protective capabilities. Regular inspection and replacement every 1–2 years, depending on water conditions and engine run time, are recommended to maintain optimal performance.
