Abstract: CATHODIC PROTECTION MONITORING APPARATUS FOR MARINE PROPULSION DEVICES A cathodic protection system monitor is coupled to an impressed current cathodic protection circuit used for corrosion protection of a submerged marine drive. The cathodic protection circuit includes one or more anodes and a reference electrode mounted below the water line and connected to an automatic controller for supplying an anode current which is regulated in order to maintain a predetermined reference potential on the protected structure. A switch selectively connects a light emitting diode (LED) lamp or indicator to between controller current to operate the lamp and monitor the change in the cathodic protection current to defelct when adaquate power is available to the anode.

Abstract: CATHODIC PROTECTION DEVICE of the Invention A marine cathodic protection device for aluminum hulls, stern drives and outboard motors, adapted for through hull installation on the bottom of a boat. Housings utilizing airfoil cross section reduce drag and afford protection for the electrode surfaces.

Abstract: A cathodic protection system monitor is coupled to an impressed current cathodic protection circuit used for corrosion protection of a submerged marine drive. The cathodic protection circuit includes one or more anodes and a reference electrode mounted below the water line and connected to an automatic controller for supplying an anode current which is regulated in order to maintain a predetermined reference potential on the protected structure. A switch selectively connects a light emitting diode (LED) lamp or other light source between the controller output and ground so that the controller current may, when tested, be used to operate the light source in order to confirm that power is available to the anode.
