Rated 3 out of 5 by from Works as suppose to! Scuppers work same as the factory ones. By design, most scuppers let some water in as the boat is rocking and the balls are moving. I added regular plugs from the inside to solve that problem and will keep this on as back-up.

I have a 16 ft center console boat. The scupper drain holes are smaller than a wine cork. Will this scupper that fits up to 1 1/4 inch drain hole work? Is the main concern the outside diameter and the mounting holes lining up?

Asked by: charlie
This scupper will work for your drain hole. I can not guarantee the mounting holes will line up.
