The answer is that first they drain most of the the water out of the engine by removing the engine drain plugs and the hoses next to the impeller, then they reinstall the hoses and plugs. Next they use an "inboard motor flusher" (google it) which looks like a toilet bowl plunger. The flusher has a telescoping rod that wedges between the bottom of the boat (over the water intake) and the ground. Instead of attaching a garden hose to the flusher, they attach a tube coming from a 10 gallon tub (pressurized with an electric bilge pump) of antifreeze. It is important that the pump be used because the engine needs the antifreeze mix to be under pressure as the engine impeller is not capable of self-priming. They then start and run the engine until antifreeze has been coming out the exhaust pipes for a minute or so.
    So, I have done all of this many times on an Indmar with a packed shaft, but my question was specifically around the dripless shaft on the newer models. Since these drain the manifolds each time, and the dealer is NOT tapping these off, I assume that they are just pulling in the antifreeze and then letting the manifolds drain back into a bucket?

        Looks like a thread revival from Dec 2014. No rush for snow just yet!!

          Yeah, I thought I was mean enough by contradicting everything he mentioned. I was gonna say thanks for reviving a two year old thread on winterization in the middle of summer! Guy's first post though, I thought it was another bu trolling when I first saw it. I was really hoping he was from Oz needing help...

            Winterizing Ilmor 5.7 (2013 X14v) for the first time. New to me. I am looking for some advice, especially things like what is different from my old MCX.

            Where will I find the connection to suck in the antifreeze to ballast and engine. I have looked but have not found.

            Do I really not change spark plugs, distributor rotor and cap? It feels wrong not to.

            What about tranny fluid?

            Anything else I may not know?

              read post #16 - I thought it was a pretty good list

              Hopefully this will answer some of your questions.

                Hello everyone, I am new to this forum. But not at all new to the use of a mastercraft boat. I like this boat. I have it since 2008. See how the boat is stored in the frost -20C in Russia. For ventilation, plastic pipes from sewage are used.
