Your water line is missing that feeds the powerhead.
That pump spring may be too short. It should apply pressure on the piston constantly as the shaft rotates.
Your brass pump piston is missing or still inside the pump cavity. It has 4 small holes on the cam end and one bigger hole on the spring end and a check valve inside of it. The two check valves and piston should be clean and dry with no lube.
There is a notch at the powerhead end of the main tube. When inserting the tube into the motor end, this notch must align with the water fitting on the bottom or water will be blocked. This means that the lower unit must be installed on the tube with the skeg aligned with this notch on the other end. (notch down and skeg down).
The screwdriver can be removed now. It only holds on to the tube.
The driveshaft is probably stuck in the bottom 2 1/2 inches of the lower unit from corrosion or dried grease. That is the bearing area.
