On a '92 Alpha 1 w/mercruiser control on the handle there are two switches - one on the outside and one on the inside. The inside (thumb side) one for trim (which moves the drive up/down slowly) is not working. The inside one for tilt (which moves the drive up/down fast) is working. The question is this....do these switches work the same hydraulic pump or different ones? Could the problem just be electrical in the switch? Could it be fluid if they run diffent pumps? If they run the same pump, does it harm anything to just use the tilt switch? Any suggestions would be helpful. This is on buddy's boat and I am not familiar with the mercruiser setup.
