[QUOTE="MudHog, post: 1227551, member: 21686"] Galvanic Corrosion is the real term. As backhoe mentioned, galvanic corrosion is the presence of two dissimilar metals with an electrical current. Think of a lead acid battery and you have galvanic corrosion. The Anode is the metal that corrodes the fastest with the metal leaving the anode and going to the cathode. The further apart the two metals are on the galvanic scale, the faster the corrosion takes place. Galvanic corrosion is the reason outboard motors have small anodes on them. The many different metals and the presence of an electrical current would corrode the metals. The water the outboard motor is in is what completes the electrical circuit and is how the corroded metal travels from the anode to the cathode. In the battery, the acid is what completes the electrical circuit. The anode on an outboard is galvanized aluminum and in most cases is the torque tab just above the prop. Some of the bigger outboard motors have anodes in the cavitation plate. The electric fence is causing the electrical current, so it is a matter of isolating the current. [/QUOTE]
