I have a 1986 Mercury classic 50 in a bass tracker tx17 of the same year. I'm having power trim/tilt issues that's I can't figure out. The switch on the throttle makes the solenoid click but does not engage the motor. The two auxiliary trim/tilt switches (one near the motor and one on the bow) don't activate the solenoid (no click sound when switched). However, if I engage the switch on the throttle along with one of the auxiliary switches simultaneously, the trim tilt works. It's slower than it was when everything worked perfectly, but it does work. So it seems like a weird issue to me, hopefully somebody here can give me some input on where to start.
