5. I don’t think my motor has this sensor because it’s the only thing I don’t get a reading for on my VesselView.

About 2 months ago my wife and I were in a shallow pond down here in a Louisiana marsh. We had been sight fishing reds in this pond with as little as 10 inches of water in some areas. All of the sudden the wind we had been enjoying died and a swarm of gnats descended upon us. I never try to power out of a pond like this but these little suckers were biblical. So I put the trim tabs down jack plate up and for the first time ever in it’s short life my Merc chewed some mud and got us out of there. The only issue was from that point on my motor would slowly loose it’s trim angle. We found the hydraulic trim assy had an internal leak so had it rebuilt. That solved the problem except since then now my motor is limited to 2300-2500 rpms. Motor runs normal until that point. I originally thought it might be in guardian mode but no tones or codes. I’ve checked voltage and it’s good. Anyway, I started thinking what I disconnected to replace the trim assy that’s a sensor and I thought trim sensor. So I unplugged it and viola I can rev my engine to normal ranges. Only problem is my motor doesn’t like it cause I now have codes and cannot dump the throttle too quickly without it limiting at 3500rpms.
Okay so finally a question right.
Is there some kind of calibration procedure that I’m missing?
Could the trim sensor be bad?
I noticed that the top pin of trim assy has a slot in it so does that slot need to be in a specific position?
Thanks for reading and your help in advance
