Applications
Specifically designed for sailboats and powerboats with larger rudder assemblies requiring robust protection in saltwater environments. Aluminum anodes are the preferred choice for saltwater, offering excellent protection against galvanic corrosion. This 5" anode provides substantial protection for rudder posts, pintles, gudgeons, bearings, and other rudder hardware from corrosion damage. Ideal for larger vessels, cruising sailboats, and boats with spade rudders or skeg-mounted rudders. Regular inspection and replacement of sacrificial anodes is essential for maintaining the integrity of your vessel's steering system and underwater metals.
