replace lower unit?

[mitch_houser]

With the lower unit out of the motor.If I can clamp the shift shaft and manually move it from F -N-R and it lock in place all 3 ways would you say that my lower unit is ok or the shift dog is bent because with it up in place it will not go into reverse.Was told by one person its fine and another the shift fork as he calls it which is fine I know what he's talking about willl not engege reverse.

Mitch, Gearcases have shift dogs, not forks like a motorcycle or auto.

As Bondo says, what is it?

Most Mercs only will "lock" into neutral. In forward and reverse the shift shaft will turn a bit in either direction.

It being a 1968 the cam and pin are likely worn due to the first problem you had....
