Removed lower unit for impeller service. Put shifter in Forward first. When checking the shifting after putting lower back on the prop movement is the same no matter where the lever is. Ratchets when spun clockwise and locks up trying to go counterclockwise like it is still in forward. Normal operation is ratcheting in forward or reverse depending on which way you move the prop, and free spin in neutral.
I pulled it off again to try to check the lower unit shifting by itself. No matter what way I turn the shifting rod I get no shifting action. Most of the time the rod can spin freely left and right lock to lock, seem to be about 270 degrees movement. Sometime it won't move after I have moved the prop, then it frees up again when it ratchets. When the prop ratchets the rod moves some when you hold it then kind of snaps back.
First question is how can I make the lower unit shift now to check the mechanism Then if it is really Ok and I am just ignorant of the action, how can I get it lined back up correctly when installing.
The Upper unit shift rod coupler does not move much at all when I watch it while someone moves the lever. Kind hard for me to understand what all is going on with this setup.
