Mercury 150 Optimax PT&T

Having trouble with getting the PT&T working properly. After rebuilding the unit with new seals and a motor and added fluid, it only goes up or down a short distance and stops. If you wait a few minutes it does it again or it might go all the way up. So today we drained all the fluid and started over. We screw out the manual override screw two full turns and manually lift the motor and set the trailering lock, remove the fill plug, filled and capped. We let the motor down manually and turned in the MOS and try to lift it using the pump switch. It only goes up a short burst and stops. We have repeated the steps several time and when removing the cap to fill, fluid with some air comes out of the fill hole, as if there to much already in the reservoir.
We would appreciate some help, we have an interested buyer coming in a couple days and want to have the PT&T working.
Thanks
Don
 
Sounds like system is getting airbound, Does system sound the same as when she was new, Have grease fittings been lubed? Does she move freely when MOS is loose? UP+down? If possible cycle the system up+down with trim a few times, then let sit a few hours so air bubbles can dissipate, Top off in upper position and retry. Keep us posted with results,please
