I have been recently gifted a Hunter 20 that has been out of the water for ten years. It's dirty and I'd like to start by pulling everything out of the cabin and doing some clean up. My question (I'm sure the first of many) is how does the bilge drain / get pumped? If I am splashing some water inside the cabin, it looks like it will flow towards the back under the cockpit, but I cannot see where it either drains or gets pumped out. I see a switch for a bilge pump. Should I replace the battery and if it works I'll be able to answer my own question?
