Anyone out there that can help with a lower unit reinstall? I brought my LU to a marina for a new prop shaft. When I tried to put it back on the motor, it does not shift cleanly every time into either forward or reverse. It seems to hang up until I move the prop position a little by hand. What I did so far is shift the boat throttle into forward and then move the small shift spline on the LU into forward then reinstall. As I said, it is not shifting cleanly every time. Did they do something wrong in the marina or am I doing something wrong. At this time, I am leaning toward the marina messing it up.
