Hello,
I have 8 total. Four in the head (three same as Lyle's, and an additional 1/2" for seawater intake to the water maker), and two at the engine intake (one for the engine heat exchanger raw water, one for the galley sink grunge faucet), and two cockpit drains. I think originally, on a stock M31, there would have only been 6, as with Lyle's boat.

I got your two names mixed up.

Thanks for the information. I'm probably better off waiting until the boat is up and out before buying anything. I don't believe my boat has had a refit of any kind in a decade, and would be surprised if any more than three thru-hulls were below the water line.
Lyle.

If you have a 1.5" in the head you should also have a .75" for the water intake on the toilet. That one should be forward of the larger outlet. Look under the sink and there should be one there for the drain. Pull off the cabinet containing the sink and your raw water intake should be right there in front next to the icebox. There are two large (1.5"?) for the cockpit drains as they drain under the waterline. They are visible left and right of the transmission about 18" away. If you don't have at least those then someone has blanked some off and I would look very carefully for those areas to check on the quality of the patch job.

I hope that you have at least one cockpit drain to drain rainwater or splashing waves taken on when under sail. Gitana Vela (M31#95) has two cockpit drains located just as described above. The galley sink drain ties into the starboard cockpit drain thru-hull line. The port side thru-hull drains only the cockpit floor drain.

Hi Northern Neighbors, Guess what! It appears that some of your rain has escaped an is down here getting Shadow an me a bit wet. Don't laugh we've had a drought in Southern California, so thanks. Shadow has three thru hulls in the head area and three thru hulls aft, engine raw water intake and port and starboard cockpit drains. As far as the two head thru hull on Shadow I've capped them off. Down here any ports of call are off limits to flushing into the open water, so for the time being I have a !! porta potty!! Hopefully in the future maybe one of thoughts Air Head, composting toilets? Just a little note on the marine plywood, joubert okoume BS1088. alliedveneer.com carries 48"x98" but they did have 5x10 pieces. If enough interest was shown they may order more. For doing the back cockpit you would only need two pieces of plywood, but maybe it would be different with the 31. Anyway it was just a thought. 48x98 $114.00. Yours truly Kathy
