I've owned my used alumacraft for 1 month. I cleaned the anodes in the motor 2 weeks ago and took it out once. I just got it back from the shop and noticed the anodes had an litter layer of "stuff" on them. This was not how they were 2 weeks ago. Do I have a problem or is this normal? I also found lots of wire ends rung my throughout the boat and have no idea where they go or if any are connected to a battery. This all has me conceded about electrolysis.
