Yes it gets cold enough to winterize in GA. When I bought my first boat 6 years ago my father in law did the whole "I've never winterized by boat in 20 years and haven't had a problem" speech. He's been through 2 blocks in the past 6 years, he now winterizes. Although fogging won't save a block blowing up, draining the motor of the water does that.

So my dealer/mechanic told me (after I had already done it) to never fog these engines here (DFW).

As you can see, there are different opinions on this.
It all comes down to the comment by MMANDLEY: it's done to coat the cylinder walls for moisture. Remember - cast iron is porous and if it's dry (no oil), it rusts fast IF WATER comes in contact. Fogging will help minimize cylinder rust if your boat will be sitting for months where temperatures are changing significantly.
When I grew up it was a common practice on carb engines and outboards. I recall reading the Merc manuals on it. Putting fogging oil down the carb to coat values and cylinders. We changed plugs about every-other-year.

At the risk of offending a few people here, a lot of people's opionions don't mean jack. Why would people not trust indmar/Ford who did all the testing on these motors. If they shouldn't be fogged, the manual would state to just drain them for winterizing. If the fogging oil would damage the cat/engine in anyway, they wouldn't tell people to fog the motors.
Even if you have xx years experience in your personal motors, indmar/ford has tested these motors many lifetimes over more hours than anyone else has experience with. I doubt any dealers charge less for winterizing by not performing this fogging.2016 Craz

I was referring to one of the best indmar certified mechanics who instructed me to never fog these engines here in our climate. When I informed him that was what the manual said to do, his response was that wasn’t what indmar had instructed him.
Btw, have fun fishing the little red spray extender out from your cylinder chamber when it shoots off the spray canMatt

When you change the oil for winter storage just add a quart of lucas oil stabilizer. Dont bother with foggining. It destroys modern engine sensors and burn up catz
