Flexible Coupling & grounding
I've helped a friend install a flexible coupling to his prop shaft. According to the instruction a ground wire should be connected across the flanges if grounding is required. Question is, if the shaft and prop are not ground and is insulated from the rest of boat system then there shouldn't be any cathodic action to eat away the prop ...right ?
