Tecnoseal X4AL Shaft Anode - Aluminum - 1-1/8" Shaft Diameter

The Tecnoseal X4AL Shaft Anode — Aluminum with 1-1/8" Shaft Diameter is an essential sacrificial component designed to protect your boat's drive shaft and underwater metal components from galvanic corrosion. Boaters operating in both saltwater and freshwater environments understand the relentless attack on exposed metal, making this anode a crucial maintenance item for prolonging the life of your propulsion system.

Constructed from high-purity aluminum, the Tecnoseal X4AL utilizes cathodic protection to corrode preferentially to your steel or bronze shaft hardware. This sacrificial action prevents pitting, rust, and structural weakening, ensuring that your engine, strut, and prop shaft remain protected. Its compact design allows for easy integration into tight shaft log installations without adding unnecessary drag.

Ideal for freshwater and moderate saltwater use, the X4AL provides reliable protection while being a cost-effective alternative to zinc anodes. This anode fits 1-1/8" diameter shafts commonly found on various vessels, including single-engine cruisers and mid-sized sportfish boats. Installation is straightforward—simply slide it onto the shaft and secure it, inspecting and replacing it annually or biannually based on your boating frequency and water conditions.
