The MG Duff electro eliminators work by making contact with the boat propeller shaft through brushes. This ensures that an electrical connection is made.
Whether you have a steel or GRP boat, an electro eliminator brush should be fitted to the shaft to provide the best protection to the stern gear.
The electro eliminator offers the most effective shaft bonding solution. By running directly onto the propeller shaft, the electro eliminator puts the anode on constant low resistance contact with the propeller shaft.
The copper graphite brushes provide a minimum of 2000 running hours under normal conditions. The electro eliminators also act to stop interference to electronic equipment, which may be caused by the rotating prop shaft.
Two models of eliminators are available depending on the propeller shaft diameter.
