    Default Winterizing Link-Best Post with Pics

    Just thought I would share this link from the Moomba chat rooms. It took me awhile to find it, but it one of the best posts I have found regarding winterizing an Indmar engine. Really helped me out a lot since I had never winterized my engine myself until this year.

    Stongly recommend checking this out if you have any questions about winterizing.

    So I think that I am going to winterize my boat myslef. My plan was to not do it all because to boat is in a heated garage but I would feel better and not have to worry if I did it. This procedure is great but it doesn't talk about the heater. My boat has one and I was wondering if anybody had any input on how to winterize that too. Obviously pictures would be great but if nobody has any handy then just instructions would be awesome. Thanks for any input.

    If you are draining everything, and not sucking up RV antifreeze, you can just take off the hoses that lead from and return to the engine. Use a wet rag to make a seal around the hose going to the heater and use an air compressor to blow it out. The water will run out the return hose into the bilge. That is what the dealers do up here in WA where it gets below zero. If you suck RV antifreeze into the whole system then you need to remove the thermostat and just run it. Removing the thermostat is pretty simple, and then it is garanteed to get the antifreeze to the heater. I am sure there are other ways to do it, but these are probably the most simple.

    if you don't have a compressor try a shop vac, you can use it to blow out your v drive as well as the plugs are a bitch to get them off the first time, and nothing comes out if you have already removed both hoses and blow or suck vac it.

    So I followed the instructions and everything went great. I figured out the heater portion too so if anybody has any questions about that, it was really easy, except getting the tubing off the engine. Those tubes are a pain to get off when they are cold! spent 30 min on one tube. I felt like I broke my hand taking one of the spark plugs out, those babies go from really tight to finger loose pretty darn quick, lol. All in all though, a great experiance and now some piece of mind for the winter. Thanks for everyone's input.

    Default Winterization Tips in MS Word Format with Heater

    ***NOTE*** I am not trying to plagerize on CAB13367.
    I copied the Winterization procedure that CAB13367 made into MS Word format for myself. I added the heater winterization process and added a checklist for materials in the front.
    ***All credit goes to CAB13367 for an excellent procedure document****

    It would be great if anyone has constructive criticism.

    Please use this as you will.

    Please download from this link OR maybe a moderator will make the .docx file available on this website.

    Default process for unwinterizing?

    I winterized my 21v last year, first time ever, with the help of my dad and now I need to get it ready for the water. I am assuming there is no real process to unwinterize it other than to do the opposite of what i did to winterize it. I obviously will check my manuals for steps and reconnect all my hoses and lines, but wanted to check with my fellow supra owners to see if there's anything special I need to do or be on the lookout for?

    Also, thanks for that doc. Ill use it this year.

    Yep just do the reverse, personally I reconnect everything after winterizing so all I have to do is hook up the batteries in the spring. I will however change my plugs and my fuel filter this year after I have run thru my old tank of gas

    Very nice job! Can you come to Northern California at the end of the Season and winterize my boat?

    ****Personal Rant ****
    To whoever thinks that the Supra and Moomba forums should be combined: Yeah occasionally the moomba forums will have a good post however they have a different crowd. I'm not saying that they suck or anything its just some of the posts over there don't make sense. I follow the Supra list because I own a Supra, I follow MC's TeamTalk because they normally have some good stuff over there and I know some of the guys over there. But I rarely glance at the Moomba pages.

    I just get annoyed by some of the people over there considering that probably half the users over there don't own a Moomba. Theres a couple Nautique and yes even some Supra owners over there. For those reasons I agree with them being separate.
