Replacing a "Grouper" dangling anode for protection from electrolytic corrosion, caused by electrolys, or stray electrical current in salt water.
During routine hull service, the port threaded rod, on which the Divers Dream transom plate anode is mounted, was observed to be actively "pinking" or showing signs of dezincification.
A "Grouper" dangling anode is clamped to the port threaded rod for extra protection from stray electrical current in the seawater.
The old anode has burned away after a year and this resulted in the pinking of the port threaded rod.
The problem was corrected by installing a new Grouper anode.
The threaded rod is tied into the ground, as well as the vessels bonding system, making it an appropriate contact point for the anode clamp.
