Because they protect submerged metals from galvanic corrosion, anodes are an important part of the boat maintenance cycle. Boat anodes, also known as sacrificial anodes, are made of three different metals: aluminum, magnesium, and zinc. In most cases, your boat is composed of at least two metals, but zinc is the third metal that has been sacrificed. A zinc anode is required to keep your boat's engine and propeller running for a long period because it always is on the water.
The objective of a boat anode, as previously stated, is to protect portions of the boat from corrosion. Galvanic corrosion occurs when two metals with different properties are electrically connected and immersed in a conductive fluid, causing them to become electronegative. We recommend replacing anodes once a year when 50% is degraded or dissolved.
