Lotta opinions online about the "proper way" to winterize an inboard marine engine. Reminds me of all the opinions on gun cleaning.
My question is, in Oklahoma's climate, if I used -75F RV antifreeze and a kit to suck it into the motor while running on the trailer, will there be enough AFZ-to-H2O ratio to keep from cracking the block?
Lotta folks say doing it the way doesn't get out all the water and instead you are better off to drain the water, then manually pour in the antifreeze with the motor off (or just leave it dry).
This Camco kit I bought let me run 5 gallons through the motor so SURELY I got enough into the block to be safe in Oklahoma? I was looking for a easier way to do things and a lot of people on youtube vids intake the antifreeze with engine suction instead of draining and filling. I called a local marine dealer service dept and they told me that the only reason they pour is so they can use less product and make more money on their service (surprisingly honest). But even still I got people coming at me saying that there is some bypass and that even if I saw it running out of the exhaust (non-toxic stuff), there is still a chance not enough got in.
What do you guys with boats do???
