In the past I have had one of the motors trim up on its own once and I changed out the Trim relay and that worked like a charm. This issue is weird because everything seems to work except the Digital display reading. here

First, visually inspect the trim sender on the bracket. It could be stuck or broken. If you can follow the wires into the boat, there should be a disconnect - take them apart and check for resistance to change in accordance to someone manually moving the sender. This should tell you if the issue is with the sender (failed, for example) or the issue is further upstream. [links]
Hello all knowing Yamaha board-hope all is well considering these times.
Now, just for fun. my display has never worked as log as I have owned the boat. BUT. if I manually move the sender arm, the display works just fine. but when the engine moves it - no good! Weird. [links]
I have searched and not able to find the issue. Does anyone know or can send me a link to review? here
Standalone trim gauge or integrated within the multifunction tachometer? more
A 2004 HPDI used a Yamaha 8 wire harness to get engine data up to the tachometer and the trim gauge. A VF225 uses a Yamaha 4 wire harness to get engine data to the tachometer and trim gauge.
Now since your boat is not using Yamaha gauges it is anyone's guess how the boat (and motor) is wired. You might want to inspect the motor to see if the four pin connector (that would normally be connected to a Yamaha 4 wire harness) is being utilized. The pink wire attached to the connector is the wire that conveys the motor trim angle to the gauge. here
Trim Sender Units
The trim senders are no longer sold individually.
The Port switch is the Trim Limit Switch. This limits how far up the drive will trim.
The Starboard switch is the Trim Level Sender switch. This sends a signal to the trim gauge.
Replacing the switches requires removal of the drive and bell housing.
These are the same procedures for replacing the Ujoint Bellows. here
The Trim Limit Switch prevents the driver from 'over-trimming" the outdrive while under way.
It is an important limiting feature which prevents damage to the drive and/or loss of control of the vessel.
Trimming the drive unit up too high while the boat is running can cause serious damage and/or injury.
When this switch fails, the TRIM BUTTON does not work. Only the TRAILER BUTTON will work.
The Trim Limit Switch is mounted on the port side and the Trim Position Switch is mounted on the starboard side. [links]
This is why the new switches are sold with the new wires are already attached at the factory. Always replace the wires when replacing the switches. [links]
Symptoms
The Trim Position Switch operates the Trim Gauge.
When the Trim Position Switch fails, the gauge usually pegs to "full up". here
Whilst out i used the trim button both on the throttle and on the motor, both were working fine.
I have tried to test the motor by disconnecting the blue and green cables.. attached one to a battery and earthed out the other, and there is nothing, but who knows if i was testing the right thing. i am pretty sure it was the cables going down to the trim/tile motor. here
Tomorrow i am going to try and get the motor off as there is visible corrosion on the outside.. who knows what is inside..
