Unable to turn motor

[Carl]

I removed the lower unit today to change the water pump and realized that the motor would not turn. I assumed the problem was in the cable so I disconnected the nut from the bracket and the steering wheel turned with no problem. The motor, however does not budge. I greased all the fittings and it seemed to build up pressure and the grease did not squeeze out where I normally expect to see it. The motor tilts up and down fine, just not left or right. It was only about a month ago that everything seemed fine and the motor moved fine also.

Any Ideas -

Thanks

Carl
