I replaced the impeller in my lower unit on my 1985, 50hp mercury. I am having trouble getting the lower unit to go back into the rest of the motor. I tried with the motor in the locked up position in neutral. I cannot get the splines to line up. I have tried turning the flywheel a little at a time and have not hit the right spot yet. What should I try next? ARE THERE ANY TRICKS FOR THIS PROBLEM? Also I had to drop the motor to down position to put it in my garage last night. I will have to put it in gear to bring it back up is this a problem? I f so what do I do next.<br /><br />shamp
