I just got my LU back from having the prop shaft straightened. The only way I can get it to stab is if the LU is in forward and the shifter is in neutral. I've tried the forward/forward, neutral/neutral and reverse/reverse. The splines just won't align. I've also tried the wiggle the shifting linkage trick. No go... Is it possible to install the shifter shaft in the LU clocked incorrectly? It is a 7 spline shaft so it's not symmetrical. I've had this lower unit on and off at minimum once every year since I bought the boat. This is the first time it's taken me more than 5 minutes to install. I'm stumped..
