Smart craft malfunction?

[hitthebricks]

I have a 2001 200 Merc. with the smart craft gauges.

The last time out the trim gauge would only read in full trailer 25.  I tried to calibrate it but not able to do so.  Today I decided to take another look at it.  I ended up looking at the position sensor on the motor.  when I removed the sensor and trimmed the motor up and down the part that should move to tell the sensor the motors position doesn't move.

When I changed the position of the part that moves on the sensor it would give me different trim angles, 16 - 25, but not the full range 0 -25.  Any ideas?

 

Thanks,

HTB

I can't answer the question on your sensor, but if the slot cut into the tilt pin isn't rotating as it goes up and down you might have a bigger issue of a broken tilt pin... I'd start with investigating that before I would dive into the sensor.  As the motor goes up, if I recall correctly, the slot cut into the pin should rotate (which in turn rotates the plastic key in the sensor).
