ANODE FLEX FOLD 55.3mm.

Function and technical context

The flex fold type sacrificial anode with a diameter of 55.3 mm is part of the boat's cathodic protection system, acting as a protective element against galvanic corrosion that affects the submerged metal parts of the hull, tail shaft, propeller and other transmission components. Its flex fold design—foldable and flexible—facilitates installation in hard-to-reach areas, adapting to complex geometries without losing protective effectiveness. Being a more electrochemically active metal than aluminum or stainless steel of the components it protects, the anode preferentially corrodes, preserving the integrity of the structural and transmission parts. The reference TEN01041 uniquely identifies this component, guaranteeing the correct selection for the intended application.

When to replace this part?

The clearest sign that the anode needs to be replaced is the visible reduction in its mass: when it has lost approximately 50% of its volume, it has reached the limit of its useful life and no longer offers sufficient cathodic protection. The review should be carried out at least once a season - coinciding with the annual beaching - and always after prolonged periods in waters with high conductivity or contamination. Replacing the anode preventively is the most economical measure to avoid accelerated corrosion of shafts, propellers and transmission accessories, whose repair or replacement involves a much higher cost.
