Re: M_Boats: M-17 early deck model cockpit drain
Dale and John, Thank You for your quick responses! Man - ya gotta love the internetz and groups like this to help you get thru the day. I will secure 4) all stainless hose clamps, A piece of hose long enuf to service galley drain and cockpit scupper drain. and replace these little devils. My boat is a late 1980 model - do you think they need to be replaced?? I suspect they are the OEM hoses. Okay just because I have nothing to do but crawl into the port cockpit locker head first on my back. Love that entry access contortionist act to get in there! Maybe I will remove my 1980 water tank finally - if I can borrow a sawzall- it woild be nice to have the space. New battery switch goes in tomorrow (handle/knob broke off old one) It is finally cool enough to work on the boat here in the desert - only the upper 90's for a high now. Very balmy for us lizard type desert dwellers. Thank You again for your help. Take Care,Have Fun, Go Sailing Gary O Team Geezer Racing.....Old and in the Way Arizona Sailing Squadron ************************************** See what's new at http://www.aol.com
Hi Gary, just to confirm, my 1975 M-17 did need the hose replaced when I got it as it was falling apart. I went to the marine supply folks at Advanced Auto and got a radiator hose that matched. My hose may have been original but it looked like a radiator hose, and if it looks like a duck, walks like a duck... Two hose clamps on you are sailing without worries.

Having been on the list for a few years now, it's interesting how these topics keep coming up. A lot electrons have buzzed on the topic of those cockpit drains. There may be some MSOG.org space devoted to this, but just in case, a refresher. For the older style M17's, before the drains were routed through a wet locker and the transom, the cockpit drains consist of a metal nipples (copper I think) molded into the aft end of the cockpit and in the bottom of the boat, forward of the transom, starboard side, and below the waterline of the boat. The metal is actually molded into the hull. A flush drain. The floor of the cockpit is higher than the waterline, but not by much. With enough weight aft to make the boat squat, water will actually back up into it. Galley models with sinks have the same nipple molded into the port side, amidships, just above the waterline, and a nipple in the bottom of the fiberglass sink, which was part of the cabin liner for the galley models. Hoses connect both drains and there isn't a seacock. As the cockpit drain is below the waterline, if the drain system fails, the boat will fill and sink, so it needs to be sturdy. Radiator hose with double stainless steel clamps fits the bill. When it's all apart, very carefully inspect the hull end nipple. I don't remember who, but someone once reported that theirs had corroded out and basically crumbled away when they took the hose off. Most likely this would be due to leaving the boat in a slip at a marina, with electrolysis in play. The point is, it happens so inspect it. It's rare and seldom a problem, but can happen. It also seems there was to be a loop of sorts in the hose, the loop rising up behind the cockpit to a point about even with the bottom of the cockpit, which acted somewhat like a check valve to prevent water from backing up. I may be imagining that one. A lot of folks have installed round deck ports in the vertical aft end of the cockpit seats, directly above the cockpit drain, to help with access to be able to get to those drains. Mine has a big one....maybe 8 to 10 inches or so in diameter. It's helpful...not only for this but to get access to stuff that ends up in the aft end of the boat, under the cockpit, including access to the bolts for the bottom rudder gudgeons. Again, not a big issue, just something to be aware of. Howard On Oct 4, 2007, at 4:48 AM, Robbin Roddewig wrote:

Howard: The fellow who had the erroded hull fittings is Bill Sylvester and the boat is Endelig. There is a detailed explanation of the refit at http://www.msogphotosite.com/M17MM.html Regards, Bill Larson M17 #632 Howard Audsley <haudsley@tranquility.net> wrote: Having been on the list for a few years now, it's interesting how these topics keep coming up.
