I have a 23' Proline cuddy. A Gil Bracket is mounted on the back with a 225 Ocen Runner. My scuppers (2) on the transom are always under water when not under way. Is this normal? I do not recall this being the case when the boat was new. I've replaced the scuppers which are the rubber flap type. Water still comes in while stopped and i have decided to plug them and use the bilge pump. Therefore the self-bailing feature does not work properly in my opinion. Any suggestions?
