Visited my boat this weekend to charge batteries and do some routine maintainence.
Located near Annapolis on the hard.
I checked the pink antifreeze in my water tanks and found it to be slushy. Then checked my engine compartment and saw the raw water strainer looked cloudy. Removed the lid to find that also was slushy. Had a new gallon left of the pink stuff which I checked and it was also frozen. Purchased the stuff at West Marine. The pink was not frozen solid but still it was frozen. Has anyone else experience this problem and how much damage is it likely to cause?
