Can a 496 be damaged with freezing temps?
I have a friend with a 496 mag ho. He stores this boat inside every winter but this year was slow to tow it to the storage facility. With the boat sitting outside we had hi/low temps of 32/19, 34/24 and 34/23. I would assume the block is safe but the manifolds? Heat exchanger? Anything else he should be concerned with?

If you are unsure, go to Petsmart and get 2 (or 3) clip on Lizard heaters. You clamp them on and either put them on a lamp timer or leave them on.
You will be surprised when you check on your boat and the engine is WARM...

The Heat exchangers need to be looked at IMO. There is a little hand pump under the hood that could have been used.

Is this 496 a closed coolant system? If so I would imagine it would be just fine. If not, it really doesn't matter what engine it is, doesnt take much to do major damage. Either way, I hope it's ok!

Three days at those temps he should be at the edge on the very concerned list . Probably not long or cold enough to do damage but he better move on it soon . $$$$$$$$$$$

Agreed. Doesn't take much to freeze the small amount of water in engine blocks acting like freezers!
