    Winterizing the Boat

    I had my boat winterized while I'm away. The work notes
    said the pump didn't want to suck up the antifreeze. They
    manually drained and introduced RV antifreeze into the engine.

    Should I be concerned about this?

    What method did they try that did not work? Place drive in a barrel filled with antifreeze, one of those winterizing kits that connect with muffs,...? If the latter these don’t always prime if the container is not up high enough and vented. How old is the impeller? You may want to just replace it and test the boat in the water in the spring.

        Yes, you should be concerned! Sucking antifreeze up through the drive is risky. The risk is "dilution"!

        Please read my write up on this subject.

          Rick: I hope the marine mechanic did it right.
          I won't be at the boat until about May.

            Sounds like they winterized in a manner that is best in my opion. Draining all water is the main thing...while I personally prefer adding antifreeze by direct pour like they did...some say this isn't needed.

            I like doing it for several reasons but that's another debate topic.

            I would much rather have them do as they ultimately did instead of how they first tried to winterize.

            I agree to make sure the impeller is working in spring but you good as far as winter protection. If it is close to time to change impellor...you may get that done and be done with it.

              Sounds like the way my mechanic does my winterizing so if done properly you will be OK.

                My 99 3055 did not have a drainplug nor does my current 80 Carver. One less thing to worry about IMO.

                      No problem. When I first read it I was confused until I saw the other thread.

                        Let me clarify my earlier comments!

                        For me, this would imply that who ever attempted to do this type of Engine winterizing (for jongleur), used one of the winterizing kits..... either Camco, Star-Brite, West Marine, etc.
                        Please.... if you have not read my write-up, please do so..... and read it twice if need be!

                        Correct! It is not necessary!
                        Pull each and every seawater drain plug......probe the open ports to clear them from any rust scale...... drain all seawater...... DONE!

                          Actually, I would be worried about the impeller in the pump. That was exactly how on my previous boat I found that my impeller is not strong enough. I tried to winterize my full system FWC by using muffs to suck the antifreeze from the hose in big plastic tank, and it did not work. In cold temperature the worn impeller vanes get stiff, break easily, and do not provide enough vacuum. I replaced the impeller immediately, and run about 4 gallons of the red stuff through the raw part of FWC.

                            Yep.... when the vanes (blades) lose their resiliency, they will not pump effectively!
                            This is why I remove my seawater pump impellers at lay-up time.

                            Yes... for a closed cooling system (better yet, a Full System), I have no problem with the winterizing kits!
                            It's the use on Raw Water Cooled engines where the problem lays!
