Description
zinc shaft collar anode for cathodic protection in seawater with a thin moulded section that is ideal for boats with limited clearance between the propeller and bracket.
Anodes are installed on boats for sacrificial protection, also known as cathodic protection. Boats are made of various metals, such as steel, aluminium, and bronze, which can undergo galvanic corrosion when immersed in an electrolyte like seawater. Galvanic corrosion occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte, causing one metal (the less noble or more reactive metal) to corrode rapidly while the other metal (the more noble or less reactive metal) remains protected. Anodes, typically made of metals like zinc or aluminium, are deliberately installed on the boat's hull and underwater fittings. So the anode "sacrifices" itself rather than let the sittings corrode.
