CATHODIC PROTECTION MONITORING APPARATUS FOR MARINE PROPULSION DEVICES Abstract of the Disclosure 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. -0-
