For several months I've had water accumulate around the water tank under the floor in my 1985 390 ec
i know the water tanks were problematic on these but this is a replacement tank and should be good. It would accumulate 15-20 gallons in a 2 week period. So I left the tank bone dry empty for a couple of weeks, water came back. Now wondered, was the refrigerator condensation leaking there. Turned frig off, water came back. Now wondered about external leaks, bilge water was freshwater so knew it wasn't bottom leak, so I recaulked all around the bow pulpit and winch and windows and stanchions etc. 2weeks, no rain, water came back. So now I had the bright idea about the a/c unit condensate. So yep, pulled the cushions and
boards away and saw a steady small flow if water over the side of the pan. Drain was clogged. Blew out the drain and now water goes down the drain like it should and the cabin bilge area is dry. It was the aft ac unit that was the problem
I hope this can help someone else find the easy quick fix early
