ANODO TIMON PAR Ø 90mm (AL)

Function and technical context

The rudder anode in pair for 90 mm diameter shafts is a cathodic protection element specifically designed to be installed on the boat's rudder, acting as an electrochemical sacrifice against galvanic corrosion. Made of aluminum alloy, it is the ideal choice for boats that navigate in salty or brackish waters, where the potential difference between submerged metals generates parasitic currents that deteriorate critical metal structures. By being consumed in a controlled manner, the anode preserves the rudder, shaft and adjacent metal surfaces of the hull, preventing structural damage that would compromise the maneuverability and watertightness of the vessel. The pair design ensures symmetrical protective coverage and optimal electrical contact around the 90mm diameter axis, maximizing cathodic protection efficiency.

When to replace this part?

The most obvious sign that the rudder anode needs replacement is a reduction in mass by more than 50%, at which point it loses sufficient protective capacity and the metal surfaces are exposed to galvanic corrosion. It is recommended to inspect the anodes at least once a season, usually during winter stranding or at each hull inspection, and replace them preventively at the beginning of each navigation season regardless of their apparent condition if they exceed one year in service. Replacing the rudder anode in time is the most economical measure to avoid corrosion of the shaft and rudder, repairs that can involve much higher costs and immobilize the boat in the months of greatest nautical activity.
