Tecnoseal X3 1 in Zinc Propeller Shaft Anode

The Tecnoseal X3 is a zinc shaft anode sized for a 1 in propeller shaft. The collar-style body fits around the shaft so the zinc can act as the sacrificial element in the underwater running-gear system, helping protect the shaft and nearby metal components from galvanic attack. Correct shaft sizing matters because the inner diameter needs to match the shaft closely for a secure installation.

This X3 has a 2.14 in outer diameter, 2.02 in height, and a listed weight of 0.88 lb. The body uses 2 mounting holes to secure the anode around the shaft. Its compact geometry keeps the sacrificial material concentrated around the shaft while leaving the rest of the underwater assembly unobstructed. Browse more marine anodes.

• Inner diameter is sized specifically for a 1 in propeller shaft
• 2-hole mounting pattern secures the collar around the shaft
• Outer body measures 2.14 in across with a 2.02 in height
• Split collar format makes the anode a serviceable part of running-gear maintenance
