IDK im just talking here throwing Murpheys law around.

I know its a lot colder in Canada then in the PNW but here the Boat dealers just make sure to remove all water then nothing to freeze. None of them im aware of use antifreeze as a freeze prevention method.
Mike, I don't think you have anything to worry about if you use this stuff as it's even safe for drinking water systems in RV's. Atlanta Marine uses something like this when winterizing motors here. Is biodegradable also so supposed to be safe for you to start up in the summer right on the lake.

Regardless, I think for the ballast system the suggestions from others of just making sure you get the water out will be OK.
