Tecnoseal X3 1 in Zinc Propeller Shaft Anode

The Tecnoseal X3 is a compact zinc shaft anode sized for a 1 in propeller shaft. Its 1 in inner diameter is surrounded by a 2.14 in outer diameter, and the anode measures 2.02 in high. At 0.88 lb with a two-hole clamping arrangement, the X3 provides a relatively small sacrificial anode option for matching shaft installations.

A shaft anode is mounted directly on the propeller shaft so the sacrificial metal is positioned close to the running gear it is intended to protect. Good metal-to-metal contact is important, so the shaft surface should be clean and free of coatings where the anode clamps in place. The two fastener holes on the X3 give the split anode a straightforward way to tighten securely around the shaft.

When replacing an existing shaft anode, match the shaft diameter first and then confirm that the surrounding diameter and height will clear the strut, bearing, and other nearby hardware. The X3's smaller dimensions distinguish it from larger Tecnoseal shaft anodes such as the X7 and help prevent installing a visually similar part on the wrong shaft size. Inspect sacrificial anodes regularly and replace them before excessive material loss reduces protection. Browse more marine anodes.
