Godfrey Premium Collar Zinc 1 1/8” – Marine Shaft Anode for Corrosion Protection

Godfrey Premium Collar Zinc 1 1/8” 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 provides reliable protection against corrosive electrolytic currents in saltwater environments.

Zinc sacrificial anodes work by sacrificing themselves to prevent corrosion of more valuable metal parts such as the propeller, shaft, and surrounding hardware. This significantly reduces the effects of electrolysis and helps prevent costly damage to essential boat components. The collar design ensures a tight and secure fit around the shaft for dependable protection.

The durable zinc construction delivers consistent performance even in harsh marine conditions. The two‑piece structure allows for easy installation and maintenance without removing the propeller.
