Attention all sterndrive owners... I can personally attest that air does not freeze. I winterized my 1987 3.0 GM 140.. by following the advice of Bondo to simply drain the engine and manifold and not worry about using antifreeze.. I did just that in October of 2013. Could not get it started the other day, took it to marine shop, they changed the points and it runs like a champ!! :joyous:. Gonna have them install a water/fuel separator too.. (I will change it over to electonic ignition later in the year) If there was ever a winter to test out winterization techniques this was it.. around here 15 days in Jan below zero... as Bondo said, cast iron gets along nicely in sub zero weather... Thank you Bondo!. drain it and put it to bed... yes ladies and gentlemen, it works perfectly... happy boating!
