Aluminium

These anodes are ideal for protecting boat propeller shafts from electrolytic corrosion. Aluminium alloy shaft anodes are suitable for use in salt waters and estuarine waters. All cathodic protection systems must be inspected annually and the sacrificial anodes renewed if more than 50% are wasted. You should check the working surface of the sacrificial anode to ensure that it is free of paint and chalky corrosion deposits. When fitting or replacing a sacrificial anode you should also replace the serrated fan disc washers under the nuts and change the anode backing sheet on wood and GRP hulls. Exposed fixing studs, nuts and washers should be well greased or painted after assembly.
