I have a 1983 Catalina I live in the PNW when it rains water runs around the lazarette cover and to the ruder post. I end up with a lot of water in the bilge after it rains. Could it be that the Nylon Washer is so old that its not doing the job any more or is the fiberglass around the post worn down so that it needs to be rebilt? Has anyone else fixed this. thank you for any help with this. greg
