Description
Aluminium side power dome shaped anode that fits on the end of the propeller, 71190A will fit SE60, SE80 and SE100 thrusters, it will also fit older models SP55, SP75 and SP95. Fitted and held in place by a bolt, it is important to use the suitable adhesive such as Loctite. side power anodes are suitable for types of water. side power anodes provide superior support compared to zinc anodes in fresh or brackish water, still providing excellent protection in salt water, and is the only anode that is safe for all applications.
Anodes are installed on boats for the purpose of sacrificial protection, also known as cathodic protection. Boats are made of various metals, such as steel, aluminum, 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 aluminum, are deliberately installed on the boat's hull and underwater fittings. So the anode "sacrifices" itself rather than let the sittings corrode.
- Weight 0.05kg
- Length 45mm
- Width 45mm
- Depth 20mm
- The mil-spec alloy includes about 5% Zinc, a trace of Indium to prevent oxidation resulting in a layer reducing the sacrificial properties of the anode
- Last up 50 percent longer
- Less than half the weight of a similar size anode
