Tecnoseal X5 Shaft Anode - Zinc - 1-1/4" Shaft Diameter

The Tecnoseal X5 Shaft Anode in zinc is a corrosion-protection component engineered for marine and freshwater propulsion systems. Designed to fit 1-1/4" shaft diameters, this sacrificial anode prevents galvanic corrosion on outboard motors, inboard engines, and other submerged metallic components. Boat owners and marine technicians rely on shaft anodes to extend the service life of expensive drivetrain hardware by attracting corrosive saltwater and freshwater attack in place of your propeller shaft and surrounding assembly.

This anode features a pure zinc construction, ideal for saltwater environments where zinc's electrochemical properties provide superior protection compared to other sacrificial materials. The Tecnoseal X5 measures 2.27" outer diameter by 2.52" in height, with a precisely drilled 1.25" inner diameter to accommodate your 1-1/4" shaft. Two mounting holes (as specified in the original design) allow for secure installation using stainless steel fasteners. The compact 1.1 lb weight makes handling and replacement straightforward during routine maintenance or seasonal boat preparation, while the zinc material dissolves predictably over time as it performs its protective function.

Replacement is recommended annually or whenever visible pitting or significant material loss appears. This anode is compatible with most outboard and inboard propulsion systems using 1-1/4" diameter shafts, including classic and contemporary marine engines. For optimal performance, ensure proper contact between the anode and shaft—clean the shaft surface before installation to guarantee electrical continuity. Regular inspection and timely replacement protect against unexpected corrosion failure and costly engine repairs.
