Tecnoseal X6 Shaft Anode - Zinc - 1-3/8" Shaft Diameter

The Tecnoseal X6 Shaft Anode in zinc is purpose-built to protect your boat's propeller shaft from galvanic corrosion—one of the most common and costly threats to marine hardware below the waterline. After years running outboards and stern drives, any serious boater knows that saltwater and freshwater environments accelerate oxidation on unprotected metal. This anode sacrifices itself to corrosion instead of your shaft, extending the life of your drivetrain by years and preventing catastrophic failure during the season.

Tecnoseal's X6 model uses pure zinc construction—the industry standard for shaft anode protection because zinc corrodes preferentially to steel and aluminum, a process called cathodic protection. The 1-3/8" shaft diameter fitment ensures secure contact and maximum surface area for active corrosion resistance in both salt and brackish water. Weighing 1.6 pounds and measuring 3 x 3 x 3 inches, this compact anode mounts directly on your shaft and requires no special tools or complicated installation—simply slide it on and secure it in place during routine maintenance or haul-out.

Whether you run freshwater lakes or saltwater bays, the Tecnoseal X6 is ideal for anyone operating inboard/outboard motors, jet drives, or conventional shafts in the 1-3/8" diameter range. This anode should be inspected annually and replaced every 2–3 seasons depending on water salinity and boating frequency—neglecting it often leads to pitting, erosion, and expensive shaft replacement. Anglers and cruisers who maintain their anodes religiously report dramatically longer engine life and fewer corrosion-related breakdowns when they're farthest from the ramp.
