OK noob question here. every time i get out of the water i pull my center and transom drain plugs. the transom is normally bone dry but the center has a decent bit of water in (maybe 15-30 seconds of flow). my question is why is the center not draining? does the water level need to be higher to get to the bilge? does the center not connect to where the bilge pump is? If not does it just keep filling up? First boat so im kind of wondering.
