Aluminum Grady Bracket on 1987 Offshore...The plug on the bottom of bracket..is it a drain plug?..can it be removed?...should it be removed to drain water from inside bracket?.... I believe my bracket is full of water....I haven't a clue as to how it would get in there..but I believe it's in there....should I bother with trying to get the plug out..If I succeed in taking it out , will I cause a bigger problem trying to get it back in??....don't want to strip anything.....I ave never tried to remove it, I mean really tried to remove it!...I have only owned the boat for 6 or 7 years now...don't know if its ever been removed...its a 1987 boat...What say you all?? Your help and expertise would be greatly appreciated.. :bang
