I have just aquired the boat and getting to know it. The midship bilge is designed to let rainwater in as it has drain holes under the deck cover. My problem is the water stays in the bilge. There must be a defective bilge pump that I have not located yet.Not sure if there is a pump there, if not there should be. If it’s draining slowly over time, there must be a pump someplace. I really think you should have a qualified tech look at what you have going on, for one, find out where the water is getting in. Seems you should get to know your boat a little better.
