Hammer, it sounds like what I had last year: a clogged drain line under the fuel tank.

When you have all that water foreward, it should drain through the line under the fuel tank into the stern where your bilge pump can get rid of it, especially under way. But if that line is clogged like mine was, when you get going you'll see it coming up into the baitwell as you described. If you open up your access in the stern, you should be able to see the end of the tube that the water is supposed to drain through. Try a stiff piece of wire, or perhaps a coat hanger, pushing it up into the tube to see if you can unclog it. That may be a quick fix. In my case, there are some old cruddy pieces of floatation that kept clogging it up. We cut a hole into the bottom of the baitwell and installed an access plate. That way you can open it up and have access to the tube from both ends. Hope this helps.
