Re: Did something freeze and potentially break?
I respectfully disagree. I never said the block was fine. I said there was a good chance that the water acted as a heat sink and prevented a freeze and asked the OP to report back because I was wondering if this was true.
I live within one mile of the shore of lake Ontario. Last week the temps in Rochester got down to the low 20's one night. At my house it never got below 30. There was at least a five degree temp difference at about 1 mile away!! When I say that there is a good chance that a boat sitting a foot or two above 57 degree water will not freeze in the given situation it was a response made with some degree of personal experience.
The only thing you got me on is that I said that if the boat was on a trailer it would have frozen for sure. That statement was presumptuous and would not have been made if the boat actually was on a trailer.
While you got me going, I was not trying to attack anybody who said it froze and I'm sorry it came off that way. I was more commenting on how people ask questions on this forum that can not be reliably answered by anyone who has not seen what is going on first hand. This thread is a good example of why sometimes asking questions on the internet creates more questions than answers. If anyone should be upset with me it should be the OP (sorry Natesms, no offense intended).
Don't think Smoke was trying to beat up on you. There are individuals every year that take chances for various reasons and its just not worth it. In some cases it turns out fine, in others, not so fine. Simply put, better safe than sorry.
I don't see where a "poll" would have helped at all. This forum is usually a great place for knowledge about the proper things to do from the simplest repairs to major overhauls, or for winterizing your boat in time for a freeze. I think the vast majority of people here that respond are basing there opinions, (whether there fact or not) on some experience, so maybe keep that in mind.
There is always an issue with a (after the fact) threads here. When a post is made about, "shoulda, coulda" type things, its many times speculation. When your talking about blocks freezing or cracking a manifold etc, the type of boat, its location, time of day, how fast it freezes, how long it freezes, is it in the water, out of the water, etc etc etc all will play into the end results. Problem with guessing if it will be ok is it can cost you lots of money.

Again, better safe than sorry.
I would like more details on how the mechanic verified that no damage occurred. Many times an internally cracked block won't show until it gets stressed some.
Ditto, I hope all is fine, but hairline cracks can show up at anytime, in the block or the manifolds.
