ANODO TIMON PAR USA Ø 92mm (MG)

Function and technical context

This pair of rudder anode, made of magnesium alloy (MG) with a diameter of 92 mm, is part of the boat's cathodic protection system, acting specifically on the rudder to prevent galvanic corrosion in fresh or mixed waters. Magnesium is the ideal material for boats that operate in fresh water or with low salinity, since it offers a more negative electrochemical potential than zinc or aluminum, guaranteeing effective protection of the metal surfaces of the rudder against electrolysis. Without adequate cathodic protection, the rudder and its metal hardware are exposed to accelerated corrosion that can compromise the structural integrity of the vessel's steering system, leading to costly grounding repairs or, in extreme cases, loss of steering during navigation.

When to replace this part?

The rudder anodes must be inspected at least once a season, coinciding with the beaching or careening inspections; The general rule in nautical maintenance indicates that they should be renewed when they have lost around 50% of their mass, since below that point their protective capacity drops significantly. Symptoms of a depleted or incorrect anode include visible pitting on the rudder blade, erosion on metal rudder shaft bolts or bushings, and, in advanced cases, abnormal clearances in hardware. Preventatively replacing the anode at each grounding is the most cost-effective practice to avoid structural damage to the rudder that requires welding, machining, or complete component replacement.
