If you're leaving your boat connected to an electric hook up over winter, Galvanic corrosion can be a problem, eating away at her hull, and anodes.
Galvanic corrosion can be a SERIOUS problem, and Earth Leakage is even worse, corroding a boat's hull or stern gear in no time at all.
The solution is a simple Galvanic isolator. You just plug it on to the end of your electric hook-up cable, and it completely BLOCKS Galvanic currents, stopping Galvanic corrosion in it's tracks. Our Plug in Galvanic Isolators are the simplest to fit. You don't need any electtrical knowledge, and you don't need any tools. You simply plug it in - which takes a few seconds.
