Out on a larson 2007 ski and fish boat over the weekend. with the heavy lake traffic we drifted to the shore. I lifted the trim, and used the ore to get us in deeper waters. I got pushed back pretty quickly into the sand and didn't realize and started the engine. The prop started, but I could tell it hit the sand. I turned the engine off pretty quickly, and the trim will not lower now. Any thoughts on what I did?
