I have a Hunter 25.5 and the electrical cables for starting the our board just come through the transom and there is a flimsy black rubber boot that is screwed to the transom (no caulking or sealant). Anyway like a lot of things on my boat it seems like someone did a half ass job. The boot is ripping out of the screws and I need to replace it, but I'd prefer to do it properly this time around. Can someone describe or send pictures of how to properly seal this type of thing?-- Jeremy
