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

Godfrey Premium Collar Zinc 3” is a high‑quality marine shaft anode designed to protect propeller shafts and underwater metal components from galvanic corrosion. Installed directly onto the shaft, this collar zinc provides reliable protection in saltwater environments and reduces damage caused by electrolysis.

Zinc sacrificial anodes work by “sacrificing” themselves to protect more valuable metal parts such as the propeller, shaft, and adjacent hardware. This process helps extend the lifespan of critical boat components and prevents costly corrosion damage.

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