What about this???

I checked the port side drain and it looks original. There is no extra wedge stuck on and puttied/marine-texed over as you saw in the pic.Although there is some putty around the drain tube on the starboard side . I think someone along the line replaced the tubes and puttied them in. The port side is smooth and in line with the hull,no addtional ramp.In the pic you can see that there is a slight gap between the front edge and the hull, when it gets light this morning I,m going to try to pry it off.
