Specs
Shaft anodes clamp directly onto the propeller shaft to protect the shaft and propeller. Size by shaft diameter — this anode fits 1″ shafts. Fit to clean, bright metal (no paint or grease beneath), midway between the stern bearing and propeller, and re-check tightness after the first run. Most owners renew shaft anodes at every annual haul-out.

MG Duff has been the UK’s leading name in marine cathodic protection since 1956, casting anodes at its own Chichester foundry with every melt batch-tested for alloy composition. Their zinc alloy meets US military specification MIL-A-18001K.
Inspect anodes at least annually and replace once 50% consumed. Never paint or antifoul an anode — coatings stop it working. Correct electrical bonding is essential; ask us if you are unsure about your bonding circuit.
