I start my motor on the hose and let the thermostat open up, then I switch to a bucket with a spigot filled with 50/50 mix of green antifreeze/water. I run the motor on that for the full 5gallons which ends up cycling through the motor and exhuast manifolds and all hoses. Everything is filled with antifreeze.

You do not want to spray fogging oil in the intake of an EFI or any fuel injected engine. Many, many posts on this in the past that will provide valuable information.
To fog an EFI engine PROPERLY, you can either: Mix up a 2-stroke batch of gas and run your engines on this small tank while running the AF through or... Remove your fuel/water separator; pour out half the gas, fill it with 2-stroke oil, reinstall and run your AF through the engine. Many people will say "I've done it for years" referring to spraying fogging oil in the throttle body, but you are NOT protecting the entire fuel system if you do this, and you run the risk of gumming up sensors. Such is why the above procedure is referred to in Mercury Service Manuals. Again, do a search. 100s, probably 1000s of good posts/threads. Oh, and please no more talk about this crap until November. |

I drain the blocks / headers, remove a few hoses to ensure they are free of water (inc sea pump hoses). Then reassemble everything. I then remove temp sensor and fill with pink antifreeze.

1)Unhook main hose coming into strainer.
2)Hook up hose from strainer to drum of antifreeze 3)Start motor (wife yells when antifreeze comes out tailpipes) turn off motor 4)Unhook hose from strainer and hook back up pick up hose 5)Strainer, heat exchanger, and headers have antifreeze on them all winter. IMO allowing air in creates corrosion. |

Think of it this way. The only way to truly guarantee you've protected your block from freezing is to drain it. If you want to refill it with antifreeze as added insurance, that's cool. When you try to fill all of the cooling passages in your system with a perfect mix / concentration of antifreeze, it's pretty difficult to guarantee you've got it right. In the words of Clint Eastwood, "So kid, are you feeling lucky?" I'd always try to drain it first - no matter how hard it is. Just my 2 cents.

"Winterization" that's like the couple months a year I gotta turn a/c off right? Lol

go south
Tow your boat to Florida and leave it down south until May 1, fly down and go boating while its 20 degrees up north.

A well respected marine mechanic from Alaska told me a long time ago "air don't freeze" and I have been doing it ever since.
I like Fixx's idea so you don't have to take apart anything but you would have to do a lot of boats to make it worth it. |
