Thanks to this thread I now have two working Mercathodes, both were totally shot. This fact would explain why my zincs were burnt off so badly last season! Walz et al, thanks for the heads up on the wire ties, the same guy must have been building boats when mine was made as there were wire ties on both engines at the bottom of the y-pipes. There was no humanly possible way to get to them. I used my inspection camera to look down there and they are beyond reach. I worked for over an hour and after cutting myself with a razor blade trying to nick the tie, I got pissed enough to not care what happened. I figured if I broke something, I'd replace the Mercathodes with zincs. So in an Incredable Hulk moment I yanked the wire harness and broke the wire tie. After that, it was relatively easy. Pull down the old unit a foot, cut, fish new unit, attach wires, repeat on the other engine, except the part with the razor blade. Its amazing how much strength you have when you are angry! The starboard tie broke with greater difficulty and when it let go I rammed my right elbow into a deck support and that is still sore, but at least I have them changed now.
BTW what do the two small relays above the Mercathode controller do? I always assumed they were part of the Mercathode system but I see they are not. Are these engine start realys or something?
