BUT if not ///after you drain the water out // by running in forward til she empties out // your problem is that there is not enough height from your drain holes to the water line // & because you have a light boat // weight becomes a issue .// the Flap will help alot / the best way to solve you latest issue is to rise the floor in the stern & move your drains higher #########################:
