HYDROMARINE ANODE 115x65x26

Function and technical context

Sacrificial anodes like this 115x65x26 mm Hydromarine act as cathodic protection for the submerged metal elements of the boat: shafts, propellers, horns, keels and metal hulls. The operating principle is based on the anode, made of an alloy with a lower electrochemical potential, corrodes preferentially instead of the noble metals of the propulsion system or hull. Without adequate anodic protection, galvanic corrosion can progressively destroy critical parts such as the propulsion shaft or the exchanger fins, generating high-cost structural failures. The reference TEN00224 corresponds to the Hydromarine range, recognized in the sector for its stable chemical composition and its effectiveness in both salty and brackish waters.

When to replace this part?

A sacrificial anode must be replaced when it has lost approximately 50% of its mass, since from that point on its protection capacity decreases significantly and it does not properly cover the surface it is intended to protect. Preventive inspection and replacement is recommended at least once a season, coinciding with the annual beaching of the boat, regardless of the degree of visible wear. Not waiting for the anode to be completely consumed prevents protected metals from being exposed to electrolytic corrosion, which can result in much more expensive stranding repairs.
