Hi, I have just fitted an OMC Trim Gauge to my Johnson 40hp 2 stroke it's a 2002.
This is a new fit so before I drilled the hole in the console I wired it up to make sure it works which it does however it gives the incorrect reading. With the engine tilted fully in the up position the gauge only reads about 3/4 high and when the engine is lowered the gauge reads at its lowest point way before the engine is down.
Does anyone know what the problem could be and how to test it?
Thanks in advance
