Thru Hull for transom drain size??

I used 1in sch 40 PVC. It's slightly recessed so that a Garboard Plug flang fits right in there. I even changed the angle of the tube, so no water would sit in the bildge.
A lot of boats will have a little water stay in the bildge unless you lift the bow real high. By changing the angle, it should stop that.
