Its about time to start the rebuild on my Mark Twain and thought I'd start buying parts. Its a 1981 2400 V CC. I have picture of port side and if you enlarge it you'll see the three holes in the hull for fittings. I assumed under the port side window those two are drain and vent for the sink, Am I correct on that? the one under the vent is for the cooler on that side. On the starboard side there is the cooler drain hole and the bulge pump drain hole the about two feet forward of the transom about just under the floor there is another hole for something. I cant see what that would be for. All the interior was gutted out and thrown in the cabin when I got it but although the sink and tank are there there is no signs of a refrigerator or live well that that could be a drain for. If I have to plug it any suggestions on how to do that? Also if those two holes are under the water line would the sink drain OK?? Thanks in advance, Chris
