Hi Josh, I found bronze threaded tees and plugs from West Marine and use marelon barb fittings. The bronze fittings have tapered treads while the marelon fittings have straight thread which adds some drama, but a good seal is possible. I used full size fittings. I don't use teflon tape, but use a blue color Herculez Megalock pipe dope. I would suggest aviation gasket for joints you don't want to take apart. This is what I used, but I'm sure there are other options and sources such as McMaster Carr.

I've been toying with a similar idea so that I can use the fresh water tanks to flush the saltwater from the engine after each use. However when I bought the boat the surveyor made a point to discredit the PVC fittings that were attached to the Marlon through hulls. I'm hesitant to replace them with Red Brass but can't find Marlon tees or nipples. What type material are the tees you chose made of? Everyone should be careful if choosing to reuse winterizing antifreeze. It takes a very small amount of dilution to significantly reduce the freeze protection Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Nov 19, 2014 9:44 PM, "Chuck S via CnC-List" < cnc-list@cnc-list.com > wrote: Glad to hear you "got 'er done". Nice job taking off. You mentioned luck. We are lucky to have such detailed weather forecasts. The Tygon tube sounds interesting. I prefer the winterizing setup I use. Long ago, I read a Nigel Calder article that all thruhulls should have a tee installed to allow easy clearing. I replaced the 90 degree ell at the engine intake thruhull with a tee. To winterize the engine, I simply remove a plug, install a barb and hose and stick it into a bucket filled w antifreeze. I hang a bucket off the boom so it hangs off the transom and after I see strong pink color, I collect the exhaust water and reuse inside the boat. I winterize the drains and collect that pink water in a bucket from under the boat. Couldn't do that this year as I'm keeping her in water, but I did collect a couple of gallons from the engine exhaust even in the water.

I found the water in the intake strainer frozen, but no obvious damage. I put a space heater in the engine compartment for 3-4 hours and gave it a while after the obvious ice had melted, then started up the engine. The antifreeze pumped through normally and all appears well. I am glad I did not leave it for 3 more days to worry about. Dave BTW- This was the second time I have used my new winterizing approach and I am very happy with it. I ran tygon tube from deck level into the engine intake port on the bottom near the keel. With the right diameter tubing, it fits snugly into the opening and form a decent seal. I then fill the tubing with antifreeze from deck level and stick the end into a bucket of antifreeze up on the deck so I get a siphon (probably not necessary with the suction from the engine but I want it up there anyway to monitor the level). Start the engine and wait for the thermostat to open (it takes a few minutes) and it sucks the antifreeze through the system. I find this much easier than trying to get antifreeze into the system from the engine compartment and it means I can watch the bucket and the exhaust while the engine is running and do it all solo.

Three days of freezing out of the water, I think you have to do something. If there truly is nothing you can do, you've done all you can, don't worry. But I always think there is something we can do. Can you call someone to get a heater on board? Can you at least get someone to put a Droplight in the engine compartment? A single 100 watt lightbulb should be all that is needed. FYI, I worked halfday Monday, took care of all my obligations making sure my three schools had heat, took a half day off, drove 2 1/2 hrs to winterize my boat in the water, in the dark, drove 2 1/2 hrs home to be able to work today.

I did the sink/shower plumbing while the boat was still at the dock. As luck (or Murphy) would have it, the nighttime temperatures are supposed to get down to the 20s for the next three nights. There is not much I can do about it now, so how worried should I be about freeze damage to the systems, especially since it now has fresh water in it from the trip up the river to the winter home.
