If you have a metal boat (or even a GRP one with an outboard or outdrive), you’ll want to protect it from Galvanic Corrosion.
We have a range of more than 8 Galvanic Isolators, and one of them will be absolutely perfect for protecting your boat.
The simplest ones just plug into your hook up cable or, if you prefer, we have wire in models – which are still pretty simple.
