Eliminator Electro

An Electro Eliminator is a shaft earthing device that connects directly to a propellors shaft, it provides a direct low resistance connection from a hull mounted anode to the prop and shaft. The typical bonding set up on a vessel is for the bonding wire to attach from the anode mounting bolt and run to the engine and gearbox, thus providing a path to the prop and shaft, completing the circuit required for cathodic protection from the anode. If there is a flexible coupling between the gearbox and prop shaft this must be bridged with a continuity wire, so the circuit is not broken.

An Electro Eliminator is used as a “belt & braces” method to provide a second (and more direct) path from the anode to the prop & shaft. The Electro eliminator has copper graphite brushes which run directly onto the prop shaft as it turns in use. An Electro Eliminator is a good upgrade for any vessels anode bonding system.
