Winterization Mystery

[JMC]

I signed up to this forum approx a week ago. It is really great and I've already learned many things about the my new jet ski. However....

I have a 12 hour old Seadoo 2007 GTI SE (130HP). I have really enjoyed riding it (60 MPH!!) and now I have winterized it for the off season. The many threads on winterization have led me to think that I don't understand something in the owner's manual. (I'm not talking about engine fogging, just the part about keeping the exhaust cooling system residual water from freezing.) The manual simply says to pour a specific amount of 100% anti-freeze into exhaust manifold via the short rubber hose that is attached to the aft end of the exhaust manifold. However, all the ongoing threads with questions on this subject make me suspect it may be more complicated than that. Is it more complicated or are the many inquiries on the subject of winterization based upons more complex (e.g. bigger engines, turbocharger intercoolers, etc) systems than mine? If I have done exactly as the owner's manual instructs, is my winterization OK?

Thanks again! You have a great forum!

as long as the manual is for YOU SKI then yes you should be fine. also did you make sure to do the 10hr maintinance?

JMC, you should be fine. The 100% antifreeze is to mix with water and keep it from freezing. If you use diluted it will be that much less effective with water.

Plus you are in Virginia and it doesn't get all that bad in VA. Up in Mass it gets very cold and that shit will freeze pretty easily. I am sure you don't get but to 35 degrees unless are you in N. VA. You should be ok.

open loop cooling......

You hit the nail on the head and really answered your own question. The basic on the 4-TEC winterize covers the SCIC (super charged-inter cooled) engines. That's why you see it in more detail. With your ski, it's just as you said, pockets of water in your water injected, tuned exhaust that your trying to protect.:cheers:
