Additional Information
The Vetus SN25B zinc anode serves as a sacrificial protection element mounted on the end nut of Vetus bronze propeller assemblies. By corroding preferentially, it prevents electrochemical damage to critical metal components exposed to seawater. Regular inspection and timely replacement of the anode are essential to maintain optimal protection levels and extend the service life of the propeller shaft system.
This replacement zinc anode is designed specifically for 25 mm propeller shafts and is supplied as a direct-fit component ready for installation.
