bilge pump
I had to install one in my 20 as it takes on water, especially when under power. I think the tube for swing keel is cracked as I have replaced all hoses, reseatd through hulls, been all over the stern holes, and when I had the cb removed crawled all over the hull with epoxy and sealed anything that looked like a break in the hull surface.I enlarged the inspection port by the cabinet amidships and mounted the bilge pump there. I connected the drain to the sink through hull. Unfortunatley I had to disconnect the sink as I could not find the right valve to keep both hooked and the bilge water tended to shoot out the drain of the sink
