I have a 1994 1780 Polar Skiff. It has the foam in the bottom and I want to know how to get water out of the bottom or how to check if there is water there to start with. It doesn't have a pump but I pull the plugs from the bottom and all I get is a little bit of water. I'm not sure how this is constructed and maybe I could add a bilge pump?<br /><br />THANKS
