I have a 1987 O'Day 272 that is suddenly collecting water in the bilge. It fills slowly...takes a couple of days to fill the whole bilge. This has not happened in the 5 years that I have owned the boat, As best I can tell, the only thing that drains into the bilge is the cooler, which I have not been using, The only other hose in ther bilge is for the hand pump. Unless there's some other source, the only other thing would be the keel bolts...hopefully there's something else that might be the source. Any ideas/suggestions?
