Hi, I have a Yamaha f90 2016. The gauge up in the dash is a 6Y5T multifunction. The problem is the trim indicator on the gauge goes from full down to full up before the motor is even half way up. I have had it a couple of years and until now it always read full up regardless of motor position. I assumed the trim sender on motor wasn't working. I started looking at it today and discovered it was simply the stop tab for the trim sensor lever was not in the right position. I moved that to where I think it should be, but now have the above problem. I didn't get a user manual with gauge and can't find one online.
