First, the fitting isn't grounded, so you don't have sense for the electrolysis protection (which isn't a question with Marelon, in any event); secondly, I'd want to be sure that you really have BRONZE in the threaded fitting before you depended on it for a while more; finally, Larry has had the boat in the water for only 6 - 7 months (or so) a year in the water -- if that changes? The boats been in Southern New England, Long Island SOund.
