there will be a billion different opinions about how to winterize - but also in the mix is what engines and drive propulsion one has is just as important for the lay up. I do know this for a fact 1000 percent buying 2 dollar and 3 dollar RV pink anti freeze is NOT a proper way to winterize nor is going to offer any corrosion protection period. Actually they can induce corrosion because of the alcohol content they all contain,. Think about it for 2 or 3 dollars how much corrosion additives can be in that mix and be profitable for the store selling it.. Merc has done the study on alot of those cheaped priced pink anti freezes that many sell. 
contain ethanol
contain ethanol
Thanks for the responses.

im not afraid ,, I open up my sea strainer , no t stats fire the engines of course one at a time . pour gallon of 100 percent automotive through it , follow up with another 50 /50 mix . fog engine till it dies , same for other motor ,, of couse making sure exaust is pure green on my tarp ive placed on the ground . drain headers , fuel boals . add stable . , pour some in the drain n toulet .even though don't use it , tender the batteries once a month , easy chit

I’ll take my chances with antifreeze and alcohol then leaving the engines void of anything...air is a bigger proponent of corrosion than alcohol. Just my opinion.

all rv antifreeze is not created equally,bup is correct on some brands and incorrect on others.in the marina i,m in if you get cought using automotive antifreeze you are booted.the owner is a stickler.

you guys are funny - Never want ethanol in your fuel but its ok in your anti freeze. Ethanol Its hard on seals and rubber and metal. - all raw water sides has rust in there regardless before one even winterizes.
. here is the ZECOL RV plus - one of the main additives is ETHANOL.

also to let you know - some engine manu marine recommend just pulling hoses and drain plugs - stab all holes to drain water - pull impeller and you are done for winterizing the water sides.
Also keep in mind with ethanol anti freeze or a form of it added into the mix -- the flash point is very LOW. In this case its only 148 F for this ZECOL plus RV AF. . WOW that is low and IMO not safe if one uses a bilge heater on top of. Be careful.

Yup I have used this for 20 years now on all my 4 different boats and for the last 13 years on 5 different boats of my buddies on the dock. Never an issue. My buddies don't drain it after running it in. I drain all the water, then run in 5 gallons of this in, then drain again. Ethanol may be bad but in this formulation it does not do any obvious damage to any engine components. Some of these engines have been torn down and rebuilt due to other issues and again, nothing was found internally to indicate a problem using good ol' cheap Zecol..

There is a guy in Canada that early this year had a cracked intake, and near as he can tell is because of using the -50 stuff (on other forum). Says he did it the same way he has done for many years on the same boat. Only difference is it got much colder then normal. Probably should have used -100 stuff, or left it empty. Now did he winterize the exact same way, was something missed, don't know for sure, only he does
All I know is air don't freeze (as Bondo puts it), so nothing inside, so no chance of anything going to break
