I have a 1978 140HP Johnson that was given to me by a friend on trade for a smaller motor. He said it was running rough after sitting for a few years and just died. Now it seems like its locked up. The flywheel only moves about an inch each way. I pulled the plugs the shined a flash light down each cylinder and when I would move the flywheel I could see all four pistons moving back and fourth. Is it possible that my bearings let go?

First thing to do is drop the lower unit and make sure that isn't the problem.
