I took my new boat (well, new to me) out for the first time today. I was out four hours; when I got it back on the trailer, I pulled the drain plug on the low part of the transom, and to my surprise, it released a gallon or more of water out of the bilge. I don't think I wanna leave this sitting in a slip very long w/o a pump.<br />However, the deck on my boat seems to be solid, and I don't see how to access the bilge to put one in.<br />Any advice?<br /><br />1978 Manatee 20 footer w/cuddy.
