Hi All. The screws for the lower left bracket for my ladder (where it attaches to the transom) are loose and I can't tighten them or get them out. I thought they were stripped so I loosed the lowest one just enough to get a needle nose pliers on it so I can pull out as I try to loosen it but it just turns and won't come out any further, as if it has a nut on the other end. Tried to see it from the bilge area but can't, let alone reach it even if I could see it. It looks to me like the entire cap has to come off to get to it. The other 3 brackets are tight but I'm worried about water intrusion where its loose. I think my 2000 is all composites and fiberglass so would I have to worry about eventual rotting? Presently its all covered in silicone sealer since I saw the problem and the ladder is useable but I imagine water will find its way in. Should I worry?
