Took the boat out this wknd... It has been sitting for about a month or so.. Anyway it ran perfect except the trim gauge was jumping all around and eventually quit all together. I have not looked at the wiring under the helm yet but if it is not a loose wire does anyone have any ideas.. Does it sound more like a gauge problem or a sending unit problem.. Boat is a 25 ft VIP vindicator with a 496HO and standard Bravo I drive.

This is the Gauge

I'll bet on sending unit. PIA to replace.
