ANODO HAMILTON JET 80X24 (AL)

Function and technical context

The Hamilton Jet 80x24 sacrificial anode made of aluminum acts as active cathodic protection in waterjet propulsion systems, absorbing galvanic corrosion that would otherwise attack the structural metal parts of the Hamilton Jet assembly. In installations with jet propulsion, the submerged components - casing, impeller, nozzle and deflector - are permanently exposed to salt or brackish water, a highly electrolytic medium where galvanic corrosion advances. quickly. This aluminum (Al) anode is the element that is deliberately corroded in place of the critical parts of the system, sacrificing itself to preserve the integrity of the propulsion assembly. Its correct installation and periodic replacement is decisive for the durability of the Hamilton Jet unit and to avoid high-cost structural breakdowns.

When to replace this part?

A sacrificial anode must be replaced when it has lost between 50% and 70% of its mass, which in regular saltwater boating usually occurs at the end of each season or after approximately 200-300 hours of use. The symptoms of an exhausted anode are visible: the material appears completely eroded, with a smooth surface, greatly reduced or directly consumed, and at that moment the cathodic protection disappears, leaving the aluminum and stainless steel parts of the jet system exposed to corrosion. The professional recommendation is to inspect the anodes at each beaching and replace them preventively before they are completely consumed, since the cost of a new anode is minimal compared to the repair of a casing or impeller damaged by corrosion.
