Has anyone had a their rear bilge crack like this (see photo)? Mine did over the weekend and salt water started seeping out of it. I have had the boat hauled out in order to find the source of the leak, but it appears that something leaked between the pan and hull. I had a diver check the keel and rudder which were fine. He did notice that air from his breather got sucked into the prop shaft area, however I have no leaking at the packing gland, that pan is "dry as a bone".The leak would fill the bilge with about 1.75" of water (not even enough to activate the pump switch). I "wet vacuumed" it out and the same amount appeared after around 24 hours. I then let is sit undisturbed for a 24 hour period and the bilge pump activated twice when it hit 2.25", and then never again. This morning there was water, but if seemed to settle in at the height of the crack and no more. The crack is approximately 36" below the waterline.I obviously cannot get behind where this crack is, so I have no other clues.Any help or similar experiences would be appreciated.
