I have had my 2003 34 MkII since 2019. This spring after commissioning, my house bank died and the bilge completely filled with water. Leak was not from the deck, seacocks or stuffing box and air conditioning had not been used. Saw heavy corrosion of the prop strut bolts, thought that was the source. Looking more closely it appears to originate aft of the prop strut. I'm thinking cracked rudder post? Can't see clearly looking in from the aft quarter lockers. Any thoughts? The attached pics show what looks like wet dirt and scum. Any thoughts, greatly appreciated.
