Well I guess I'll be glad mine are already apart in a pile

exactly why i use automobile antifreeze . drain n fill in fall . drain in spring. refill blocks with water . too dam expensive to be guessing .. 50 /50 is good to - 34 . it got really close couple times . so i went and dropped a light in the bilge of both my ski boat .and the powerboat . my brother used the pink . hes worried . although both are indoors so should be a little warmer inside .

Maybe a dumb question but why wouldn't a person use auto antifreeze?

The green stuff is supposed to be bad for the environment, the pink stuff isn't. I have no idea if this is true or not. I have the pink stuff in my engine. It's only gotten into the teens down here, so i'll probably be fine.

Gotcha. Well it was -9 last night and not much better tonight. I sure hope everyone's engines are ok in this frozen tundra!

Oh and it was 69 degrees last year today

He tested the antifreeze mix in the blocks and it was 30% water, 70% A/F.

This winter has been extreme.

I'm glad I drained mine, but i'd be lying if i said I wasn't nervous. I drained them the refilled with pink through the thermostat housing. First time on 500efi's... followed the book. Sure am glad I didn't just run it on the bucket.

If my engine freezes then the wife loses her argument that it runs just fine . :whistle:

Don't wanna hijack the thread, but how do you know you have drained ALL the water out?

I pulled my engs out to do some steering linkage repairs a few weeks ago. Opened the drain plugs on the side of the block and figured that would do it, but every time I moved the eng, some more water would come sloshing out. Short of rotating the engs side to side 45 degs or more on an eng stand, how do you know it's all out?

Also, the raw water/eng oil/power steering heat exchanger on my boat has a small drain plug on it, but if the engs were both installed, there's no way to get at it.

Scary stuff abt the RV antifreeze. I always assumed it was similar to the green stuff in regards to freeze protection. Sounds like supplemental heat is the best, then just hope the power doesn't go out for any length of time.
