"Anyone have any ideas where to track down a propblem with my stern drive trim pump, this is a 1975 mercruiser 233, and the pump will power the drive up, however it will not power it down, the motor only runs when pushing the down button and the drive does not go down, after hitting the up switch a half dozen times, then the down function works, just to have it act up next time, please help, thanks"
