Godfrey Collar Zinc 4 1/2” – Propeller Shaft Marine Anode

Godfrey Premium Collar Zinc 4 1/2” is a heavy-duty 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 in saltwater environments.

Zinc sacrificial anodes work by sacrificing themselves to protect more valuable metal parts such as the propeller, shaft, and surrounding hardware. This process helps reduce the effects of electrolysis and prevents costly corrosion damage to essential boat components.

The collar design ensures a tight and secure fit around the shaft, while the durable zinc construction delivers consistent performance even in harsh marine conditions. Larger shaft anodes like 4 1/2” provide increased protective mass, making them ideal for bigger vessels and high-demand marine environments.

The two-piece structure allows for easy installation and maintenance without removing the propeller.
