KAD43 trim potentiometer gear slipped a notch

[DavidJ]

Due to crustation build up on the 'rack' when I trimed the leg up it slipped a 'cog' and now reads -7 insted of -5 in the fully down position. I note that the potentiometer is fixed and has no adjustment.
Any easy way of making the correction?

Trim up to about +20 or so, undo the small screw the secures the end of the track, push the track to the side a little to give you enuf space to twiddle the potentiometer one tooth anticlockwise and re-engage (it's probably only jumped one tooth).

Thanks dv
That's the kind of solution I think I'm looking for. I'm not sure why the leg has to be raised. Isn't the track end easier to get to with the leg in the down position where more of it is exposed

If it's fully down, the potentiometer is v.close to the top attachment. If it's fully up, it's hard up against the bottom securing screw. About half way, you should be able to get enough wiggle to shift it one cog.

I think that you will find there is soem adjustment on the potentiometer in te inside of teh transom platefrom memory 2 scres to loosen slightly and away you go. if it has just slipped and now reads -7 instead of - 5 i would be inclined to leave alone for teh time being until it gets service. If you use the gauge to trim then you just need to -2 from whatever you normally fun them at which i suspect is 0?

Thanks dv, I get it now. Very neat trick.
Also thanks to Steve. Yes there is a fork thing held by one bolt which might just give me just enough slack to take up a couple of digits.

The problem with doing it from the inside is that you don't know where '0' is, the rule of thumb is to set the drive so that the cav plate is horizontally inline with the bottom of the hull when viewed from the side, which represents '0' trim, then you will have about minus 3-5 when down and about plus 5-6 up at which point the trim button should cut out preventing you from raising it too high while driving, although in my experience most boats will only go plus 3-4 max before the prop begins to ventilate anyway.

Thanks Spannerman, I was hoping to get your input on this one and I assume you are in agreement with the input of others (or I'm sure you would have said)
Your information is duely noted, thanks
