Godfrey Collar Zinc 4” – Propeller Shaft Marine Anode

Godfrey Premium Collar Zinc 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 provides reliable corrosion protection in saltwater environments.

Zinc sacrificial anodes are essential in preventing corrosion on metal boat parts that are exposed to seawater and other electrolytic conditions. By “sacrificing” itself, this zinc anode protects more valuable metal parts such as the propeller, shaft, and underwater hardware from deteriorating due to electrolysis.

The collar design ensures a secure, tight fit around the shaft, while the high‑quality zinc construction delivers dependable performance for marine use. This two‑piece zinc anode is engineered to be easy to install and maintain, providing long‑lasting protection where it matters most.
