I winterize mine myself every year, with a easy two step process.

1st. Ship it to Miami
2nd. enjoy it all winter

I know many stories and even watched a friend crack manifolds and engine blocks when the boat was winterized. I subscribe to the idea that winterizing is only 95% and personally I am not one to gamble even %5 on my beloved boats. I use heaters in the bilge and use a remote sensor to monitor the temps around the engines. So far this year all has been well with temps at 13° the engines are comfy at 65°F. When I get my shop built the boat will be inside a heated shop. That is my idea of winterizing.

I hope the best for all that have to winterize. It is a terrible thing for the opposite season to ruin our favorite season by way of boat damage.

If you used the green stuff you'd probably have a couple nice tomato plants, a few pepper plants, and beautiful tulips growing .

I've been worried for weeks now. I drained entire system and filled blocks with pink RV antifreeze through the coolant sensor at the water neck. I trust it's full of pink, but it's been f*ckin cold.

I think next year, I'll use the green stuff as this has been a very strange winter for our area.

I've always used the pink stuff and never had issues. I'm not a big fan of waiting for the stat to open then hook up the ears, I'm always afraid the stat will close. My 350 MPI I filled manually after draining all the water. My 454's I drain what I can remove the stats and run the pink stuff. As long as it doesn't expand your good. It goes in the plastic plumbing and works fine. I think the big issue is the expansion and I believe the pink stuff does expand as water does.

it does not

Just checked my 1/4 gallon of leftover pink . Outside temps have been consistently low single digits during the day and into the below zero temps at night . Wind chills of negative 17* plus or minus . Pink antifreeze is still in liquid form . No worries .

I know. Typo

Now for those of you wanting to upgrade and the wife is saying no...

Here is a perfect excuse to do so.

"Honey the block cracked and they need to be replaced. I will sell the old motors as parts and use the money to upgrade a closed cooling system so it can't happen again."

aquaforce what is a safe heat source? I was going to drop a light in the engine hatch but didn't like the idea with the gas fumes.
