I have a 1988 150XP, wherein the trim gauge was working, but suddenly does not work. Also, I have noticed that when under throttle and trimming out, the motor will only trim to a certain point, and then stops. When sitting still, I can trim it fully up and down, though. Any ideas on what might be going on? I was going to start by making sure the fluid reservoir was full, then go from there.

Does this model have a limit switch that only allows it to trim so far? Do I have a bad sensor somewhere?

Sorry, I'm a noob on these boat engines, but I do appreciate your help!!

It only TRIMS so far.----Then the TILT cylinder takes over.-----The TILT cylinder does nothing at full throttle !

Thank you. I would assume my gauge issue is probably something related to wiring or the sending unit, correct?
