I know my 265 does drain to the forward bilge when sitting in the slip. Reason #1 to keep that front bilge pump functioning. Once water builds up there (about 4" in my estimation) it naturally starts draining to the rear. As Hookup said. there are two tubes running under the mid section of the 265. But it depends what the prior owner did with plugging or not.
To your original question, where is the water coming from? Anywhere if your front is not separated. Main areas in my boat are the rear deck caulking (or lack there of) and the round pie plates.
