I'm looking at installing transom scuppers w/flapper but am curious if the flappers truly keep out unwanted water when several people are standing at the transom or when launching the boat at a ramp. I am looking at the Marine East 2"x6" oval scupper and Centek 3" round scupper. I can see where a following sea wave will "push" the flapper closed but while the boat is at rest with a few fishing buddies at the transom is a concern of mine. Do the flappers really stay closed?
