Hit the lift, problems?

I keep my boat on a lift. The lift has 2 aluminum bars running the length of the boat and 2 others forming an H. Anyways the tide was lower than its ever been and my prop actually hit one of the bars. I had just put it in gear so it hit really slow but made a real loud noise. I took the boat out and whenever i would put it in gear it would make a weird noise kind of a grinding noise plus the transmission usually makes a slight buzzing noise and now its louder. My prop is bent but my shaft seems fine. Could something be wrong with the transmission?}
