Well I goofed big time. I think I removed the the pivot screw from the shift mechanism. Now when I put it into gear, forward or reverse, I hear a slight clank/grinding. How bad did I screw up and what can I do to fix it. I'm guessing I'm gonna have to take it to a mechanic and have the lower end torn apart. Also I can turn the prop by hand when its in gear and I'm pretty sure that's a bad thing.
