Ok guys, I took my airboat to strawberry for the first time to try ice fishing with it. It was awesome going out there, but after hours of fishing we went to leave and it was frozen to the slushy later on top of the ice. It took hours to get it going again and I'm unsure why or how to prevent it from happening again.

So my first question is how can I prevent this in the future. And second why would it be so hard to break free? I would think that once we moved it a few inches that it would be free and go but no. It took hours of moving it a few feet at a time to finally get to some packed snow before it would start going again good. Any suggestions would be great, thanks
