"never ever never run the driv
"never ever never run the drive anywhere but fully down.
Your unit if it is a hydro-mechanical unit can't shift unless it's running.
Never run a stringer unless water is going to the drive.
So are you trying to shift it while it's off the motor?
Ok before you tear into the drive, hows the oil look.
You can disconnect the cable that runs from the throttle , at the shift converter and try to shift it while it is running bye moving the lower cable.
Got a pic of the shift converter.
And a side pic of the drive?
Maybe someone upgraded the drive before you got it to a fully mechanical shift.
I will be able to tell bye looking at the side pic of the drive.
never saw a clymer manual omc kind. What does it say about the hydro-mechanical unit? Does it break it down."
