Hello, I have searched these forums over and over and have not found the answer to the question I am going to ask. As others have done in the past I loosened the piviot screw on the side of the lower unit when changing the L/U oil. I believe that the prop had been spun after the screw was loose. I have read the repair manual on how to fix this problem but is does not mention and neither do any previous posts on how tighten the screw and set the controls so that the motor shifts into the gears properly. Any help is greatly appriciated.
