SLEIPNER PROPELLER ANODE TEN01054

Function and technical context

The Sleipner propeller anode TEN01054 is a galvanic protection element designed specifically for Sleipner propulsion systems, where it acts as an electrochemical sacrifice to protect the propeller and the metal components of the tail shaft against galvanic corrosion produced by the action of salt or brackish water. Being made of an alloy with a higher anodic potential than the stainless steel or bronze of the propeller, it is it that corrodes instead of the structural parts of the transmission system. Its correct installation guarantees the integrity of the propeller, shaft and hub, avoiding pitting, material loss and, ultimately, serious mechanical failures during navigation. Without this anode in good condition, galvanic corrosion can silently attack the most expensive components in the axle line.

When to replace this part?

Propeller anodes should be inspected at least at the beginning and end of each sailing season, and replaced when they have lost approximately 50% of their mass, show irregular erosion, cracks, or have partially detached from the hub. An indirect symptom that the anode has exhausted its useful life is the appearance of pits or reddish oxidation spots on the surface of the propeller or propulsion shaft. The professional recommendation is to renew the TEN01054 anode at each annual grounding without waiting for it to be completely consumed, since the cost of this component is minimal compared to the repair or replacement of a propeller damaged by galvanic corrosion.
