I have a 1999 90hp Johnson and the pump and motor work good on t&t but the up button on the shifter dont work , the down and trailer buttons work up and down
checked power all the way back to motor good but cant follow it through motor looks to disappear, power leaving from engine cover tilt, had power from the switch on shifter
That motor likely has a trim limit switch on the tilt rod. See if it is out of adjustment or defective. Trace the blue/white wire from the relay box to the trim limit switch.
