I've been getting some pitting near my props and I was going to epoxy some strips near that area. Do they only work if grounded to the hull? Or do they function just be being there?

In the 20+ yrs I've been following Marinette forum posts, no one has suggested or reported attempting to mount anodes by attaching them to the hull. Way, way too much risk of failure (although other items such as CAPAC, depth sounders do get attached to the hull because they are sealed with a marine caulk and anodes are not).Red5 wrote:My anodes are getting eaten up and there was still some pitting. I do Not want to drill through the hull to mount additional stuff near the props so I guess I will just replace what I can where it was originally placed.
