MG Duff

Product Overview

MG Duff is a well-known manufacturer of marine anodes, including those designed for saildrives. Saildrives typically have anodes designed to fit on the gearbox housing. These anodes are essential for preventing corrosion on the saildrive unit. Whatever style is used, we recommend the fastening screws are assembled and tightened with a small amount of liquid threadlocker to prevent loosening, then tested for electrical continuity after fitting. Changing the propeller material (i.e. from Aluminium to bronze) may require additional anodes. If fitting a folding propeller, check if it has an integral shock absorbing sleeve, as this can isolate the propeller from the Saildrive anode. In this instance the propeller normally has extra anodes fitted to the hub.

• Kit suitable for Saildrive models: Yanmar SD 20 / 30 / 31 / 40 / 50 sail drive without adaptor plate
