For the last week, I have been getting water in my bilge in my 272 around the shower grate area. It is not coming in around the keel bolts but it appears to be water trapped between the floor and the bilge in the head area. I do not use my head and the intake seacock for the head is bone dry and is always shut off. I have replaced the port gaskets but they still leak some but I capture the drips in a pan. I just completed a bulkhead reinforcement project and the bulkhead is bone dry. Has any one else encountered this?
