Aluminium anode kit for Volvo 290 duo prop

Aluminium anode kit for Volvo 290 duo prop Kit including the main aluminium anodes for the Volvo Penta 290 duo prop base. The anode is a device that protects important metal equipment in contact with water from corrosion. This is known as a sacrificial anode. Anodes need to be cleaned and replaced regularly, as they are no longer effective after 60% wear. In salt water, choose zinc alloy or aluminium alloy anodes. Aluminium has the advantage of being lighter and less polluting. In freshwater, magnesium anodes are preferable.
