MERCURY TAIL ANODE 94286T1

Function and technical context

This tail anode is an anti-corrosion protection component that works within the marine cooling system of 25 hp Mercury engines. Installed in the tail area of ​​the engine, it acts as a sacrificial element that preferably oxidizes in the presence of salt water or brackishwater, preventing galvanic corrosion from attacking the critical metal parts of the engine block, crankcase and transmission components. Its controlled degradation preserves the structural integrity of the propulsion assembly and guarantees the reliable operation of the cooling system throughout the navigation season.

When to replace this part?

The tail anodes gradually wear out due to galvanic corrosion, especially in salt water where consumption is more rapid. It is recommended to inspect the condition of the anode at the beginning of each sailing season and replace it when it is worn by more than 50% of its volume, or at least once a year if the boat is used frequently in salt water. Preventive replacement avoids surprises at sea and guarantees maximum protection against corrosion throughout the entire navigation period.
