Volvo Penta Magnesium Ring Anode for 120S and MS25S Saildrive.
Please note this is a Magnesium anode for freshwater use. A Zinc version can be used for saltwater, but these are being phased out in 2022 and replaced with an Aluminium anode. Anodes should not be mixed on any installation.
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 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 Saildrive.
