Martyr Anodes Zinc Shaft Anode for Saltwater
Martyr zinc shaft anodes protect boat propeller shafts from galvanic corrosion in saltwater, shielding stainless steel and bronze running gear. Read more..
Product description
Martyr zinc shaft anodes are designed to protect boat propeller shafts and other underwater metals from galvanic corrosion in saltwater and brackish environments. Made from high-purity zinc, these sacrificial anodes corrode preferentially to shield stainless steel and bronze running gear, extending the life of critical components. Precision-cast for a secure fit around the propeller shaft, Martyr zinc shaft anodes ensure reliable electrical contact and consistent protection. Trusted by boaters worldwide, they are an essential defense against corrosion for vessels operating in coastal and offshore waters.
- Interlocking halves
- Full shaft contact (100% circular radius)
- Extra alloy around the fastener
- Easy installation underwater
- Bolt retaining washers prevent anode from falling off.
