Tecnoseal X3AL Shaft Anode - Aluminum - 1" Shaft Diameter

The Tecnoseal X3AL Shaft Anode — Aluminum is a marine-grade sacrificial anode engineered to protect submerged metal shafts from galvanic corrosion. Designed for 1" shaft diameters, this component is essential for boat owners, marine facilities, and anyone operating equipment in saltwater or brackish environments where corrosion poses a constant threat to machinery integrity and longevity.

Constructed from high-purity aluminum, this shaft anode operates on the principle of galvanic sacrifice—the anode corrodes preferentially to the steel or other metals in your propulsion system, effectively drawing corrosive forces away from critical components. With an outer diameter of 2.14 inches and a height of 2.02 inches, the X3AL delivers substantial surface area for extended service life. The dual-hole mounting design ensures secure, vibration-resistant installation on standard shaft configurations, while the aluminum composition guarantees reliable performance across freshwater, saltwater, and mixed-salinity applications.

This anode is ideal for inboard engines, stern drives, outboard mounting systems, and industrial water pumps operating in corrosive environments. Regular inspection and periodic replacement—typically every 1–2 years depending on water conditions and usage—will ensure maximum protection of your shaft bearings and propeller hardware. The lightweight design (0.4 lbs) makes installation and maintenance straightforward, and the proven Tecnoseal brand reputation ensures you're investing in a component backed by decades of marine engineering expertise.
