I made a visit to winter storage yesterday in Toronto.   I found ice in the bilge.  As part of winterizing, I put in a few inches of -50 RV antifreeze, but water must have seeped in.   No freezing in head, and other places RV used.   Top few ccs in bilge was solid ice, but bottom still fluid.

I plan to return with heat gun later in week and get all cleaned out.  

Question is, what do I look for in terms any signs of damage.    Any others had any bad experiences with icy bilge?

You can get a lot of water in the boat from condensation, particularly if we go through a number of freeze/thaw cycles. Don't worry about it. The sides of the bilge are not parallel, so the expansion of the ice won't do anything bad. RV antifreeze really isn't necessary. Whatever you do, don't put engine antifreeze in the bilge; it seems to create worse issues.

Plumbing anti-freeze (usually pink or purple) can be either Propylene based or alcohol based. If it's alcohol based, it should not be used in engines as a coolant as the alcohol will attack rubber seals and hoses. Also, its protection is dramatically reduced if it mixes with water and thus is not a good choice given what we're trying to achieve here -- freeze protection. I always look for -100 so hopefully water doesn't weaken it beyond the actual outside temp. The bilge isn't four sided so you don't get expansion pressure like in the internal passages of your engine and cracking . I wet vac mine out and thats it.
