Fitting Instructions for Steel Hulled Vessels

Home > Leisure Craft > Fitting Instructions > Fitting Instructions for Steel Hulled Vessels

The main points to remember are:

The anode should be position on the outside of the hull below the waterline under the turn of the bilge.
The anode should not be positioned forward of or in line with Echo Sounding Transducers or log Impellers.

Anodes may be welded or bolted to a steel hull

NOTE: When fitting and replacing Bolt-On Anodes always ensure that the serrated fan disc washers are replaced.

DO NOT PAINT THE WORKING SURFACE OF THE ANODE

To provide the best protection to the stern gear the shaft should be fitted with an MGDUFF Electro Eliminator Brush and earthed to the hull. Additionally the gearbox should be bonded to the hull using 4mm2 multi strand cable and any flexible couplings in the shaft should be bridged with a copper strap or cable..

The MGDUFF Electro-Eliminators offer the most effective shaft bonding solution. 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 will give at least 2000 running hours under normal conditions. The electro eliminators will also remove the irritating interference to electronic equipment caused by the rotating shaft.
