Trim Indicator Stopped Indicating

[MarineWay]

This isn't the end of the world I know, since the trim motor works fine, but I guess I like everything to work as advertised. The Trim indicator on my integrated guage, suddenly started indicating full up (the meter keeps bouncing off the top shaded segment) regardless of actual engine/trim position. I understand this might be a resistance issue with the trim sending unit...but I haven't the slightest idea where that is, or what it looks like! Any ideas? 2004 115 HP 4 stroke.

look on your tilt tube,front of motor that it pivots up on when tilting.on the port inner side you will see a black band/lever arm sensor which is probably seized.lube with your fav and break loose lever.bad yamaha design but keep the spring greased after.
