Re: electrolysis on mast/boom connection

Paul Osterberg

After turning the vertical bolt holding the boom a few turns the potential difference went down from 0,4 V to 5 mV, I will try to remove the bolt and apply Tef-Tec to it, but it's rather hard work to turn it, but 5 mV much better than 400 mV. I also notice some potential difference (5-20 mV) between the smal screws holding the "folded cover" for the slot in the mast, Can be worth measuring other areas where SS and aluminum are bonded together
