Godfrey Premium Collar Zinc 2 3/4” – Marine Shaft Anode for Corrosion Protection

Godfrey Premium Collar Zinc 2 3/4” is a marine shaft anode designed to protect propeller shafts and underwater metal components from galvanic corrosion. This collar zinc installs directly onto the shaft and reliably protects against corrosive electrolytic currents in saltwater environments.

Zinc sacrificial anodes work by sacrificing their own material to prevent corrosion of more valuable metal parts such as the propeller, shaft, and nearby hardware. This significantly reduces electrolysis damage and helps extend the lifespan of essential boat components. Collar design anodes are specifically made for direct shaft mounting and effective cathodic protection.

The robust collar design ensures a secure and tight fit around the shaft, while the high‑quality zinc construction delivers consistent performance even in harsh marine conditions. The two‑piece structure allows for easy installation and maintenance without removing major parts.
