Volvo Penta Magnesium Outdrive Bar Anode.
Genuine Volvo Penta Anodes are the OEM anodes as fitted from new on you leg or sail drive. The anode protects the drive, engine and propeller from corrosion due to electrical currents in the water. When you change your anode, make sure that it is not painted and that it has a good contact via the bolts and metal surface to the drive.
If your anode is worn away by 33% or more, it is advisable to change it, as more of its surface area has been worn away and the remaining anode will wear away much quicker. Please note this is a Magnesium anode for fresh water use. The magnesium version is only suitable for fresh water, aluminium which is suitable for brackish water and Zinc for salt water.
