KAD43 Which screw behind the trim display for adjustment.

[DavidJ]

One of my trim displays is reading -3 instead of -4. On the back of the trim display are two adjusting screws (difficult to see but one is coloured blue) Which one do I 'twiddle' to make the adjustment.
I know I could make the adjustment from the sender unit but this way could be potentially easier for me.
Guidence appreciated.

Why bother.. It's probably a little bit of muck on the sender unit or drive unit preventing only a fraction of a degree to maximum Down tilt !!!

Didn't realise you could do it on the display. Thought it was a case of 'calibrating' the plastic 'toothed' thingy on top of the drive in conjunction with the wheel on the transom shield...?

Apparently so! There was a posting a few months back about it which has prompted me to have a go. I'm hoping to trawl in some of the original 'posters'

This relates to the ones on my boat which is 1993 model so newer ones may be different. On the back of the instrument there is a switch which should be sealed for DP drives. The seal has to be broken for SP drives and is used to fix the trim limit to 5 deg and 12 deg respectively. Also, in the centre of the backplate is a potentiometer which can be used to adjust the trim figure which should be -4 for a 12 deg transom. Hope that makes sense.

Thanks Eddie
I didn't see a switch so maybe mine is a bit different although it sounds like the principal is the same. I might just leave this one unless someone can come up with specifics on my setup.
