My center console fishing boat has the 6" oval transom scuppers with the hinged flapper door on the exterior side (PVC plastic). If backing down or facing aft in a following sea the flapper door is pushed upward, allowing a surprising amount of water to fill the cockpit. I've thought about weighing the flapper door down somehow but I think the amount needed to counter the rush of water would be prohibitive. The flapper door is top-hinged.
Anyone have an idea how to negate the flapper door from being pushed upward when outside sea water flows toward the transom?
