Godfrey Premium Collar Zinc 1‑3/8” – Marine Shaft Anode for Corrosion Protection

Godfrey Premium Collar Zinc 1‑3/8” 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 corrosion protection in saltwater environments.

Zinc sacrificial anodes work by sacrificing themselves to protect more valuable metal parts such as the propeller, shaft, and nearby hardware. This significantly reduces the effects of electrolysis and helps prevent costly corrosion damage to essential boat equipment.

The collar design ensures a secure, tight fit around the shaft, while the durable zinc construction delivers dependable performance even in harsh marine conditions. The two‑piece zinc structure allows for easy installation and replacement without removing major components.
