[QUOTE="Syncrowave, post: 325983, member: 12517"] I've been boating in saltwater most of my life and I have never heard of this. I've heard of bonding everything metal that goes through the hull [i]together[/i], so that you don't need to attach a zinc anode to every seacock and through-hull fitting, but never that it should be connected to the negative post on the battery. Seems to me that unless the (+) terminal is somehow in the circuit, it's not going to make any difference. At any rate, unless you keep your boat in marina near boats that are using shore power, stray current isn't much of an issue. There will be current because of the dissimilar metals submerged in the electrolyte (seawater) but that's just the nature of a galvanic cell. [/QUOTE]
