Volvo Penta Magnesium transom Anode for SX from 2007 onwards and DPS Outdrives
Genuine Volvo Penta Anodes are the OEM Magnesium anodes as fitted from new on your Sterndrive leg. 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. The magnesium version is only suitable for freshwater, and aluminium, which is suitable for brackish water. Zinc anodes are for salt water.
