I checkout out your gallery, thankfully it wasn't any worse. I will definitely be going through my boat from top to bottom before she hits the water this year. Clean up anything I missed and I think I am gonna add a fish finder and maybe a light kit before season too.Hopefully no issues for you. Be sure to check though when you open it up. Ours is outside also and everything looked fine until I opened it. Cover was ok and the chewed holes were inside where the top met the curves on both ends. I have used moth balls and dryer sheets in all the boats I've had and that was the first time any problem. I had not put any into the boot until this year after it was damaged last year. Pictures of damage in my gallery if interested.
I didn't see any indication of rodents when I was in there the other day, but will know more later.
