Tecnoseal R2 Rudder Anode - Zinc - 2-13/16" Diameter

The Tecnoseal R2 Rudder Anode in zinc is an essential cathodic protection device for saltwater and brackish-water vessels. If you've spent years on the water, you know that galvanic corrosion silently attacks underwater metal components—rudders, shafts, and fittings are constantly exposed to electrochemical degradation. This 2-13/16" diameter zinc anode sacrifices itself to protect your rudder assembly, extending the lifespan of one of your boat's most critical steering components. Whether you're a commercial angler, weekend boater, or cruising enthusiast, investing in quality rudder protection is non-negotiable if you want reliable performance season after season.

Tecnoseal's R2 anode operates on the principle of sacrificial corrosion protection: zinc is more electronegative than the steel or bronze of your rudder, so it corrodes preferentially, leaving your rudder intact. The 2-13/16" diameter size is engineered to provide adequate current output for standard rudder applications without excessive drag or weight penalty. Zinc anodes are ideal for saltwater environments and perform reliably in temperatures typical of recreational and commercial fishing grounds. The compact 3 x 2 x 3-inch footprint and 0.9-pound weight ensure minimal impact on boat balance while delivering proven corrosion defense. Regular inspection and replacement every 1–3 years (depending on salinity and boat usage) keeps your steering system performing at peak efficiency.

This anode is ideal for inboard and outboard installations where rudder protection is critical. If your vessel spends extended time in saltwater—whether you're a tournament angler, commercial operator, or cruising sailor—the Tecnoseal R2 is a cost-effective insurance policy against unexpected rudder failure. Installation is straightforward: the anode bolts directly to the rudder's trailing edge or strut, requiring no special tools or modifications. Always verify your specific rudder design and fastening method before purchase, and consult your boat's manual if you're uncertain about compatibility. Keeping spare anodes on hand ensures you can replace a depleted unit quickly, minimizing downtime and keeping your boat ready for the next trip.
