Alan, I would be careful of magnetic or of those thin film pots.
Reading the material on them they are activated by a sliding contact or a
magnet bringing two surfaces together. It is possible that the water pressure
may activate the entire film and give you funny readings.
I am not saying that would definitely happen but I think you
need to be sure they will work under pressure. Chs, Hugh

It has the largest internal diameter hole I could find ( about
17mm ). It looks like you
can bore it out to 25mm, so with the casing it could possibly fit
a 20mm shaft.
Will let you know in a couple of weeks. Have also ordered a linear
100mm item.

I think I'll buy an off the shelf $10- version & have a go at
adapting it.

Hi Alan. Ya, an off the shelf unit makes more sense. You can get a
couple as spares and still be way ahead.
I like the round "doughnut" ones too. I saved the link
and am looking at using that design. Simple, easy, and hopefully reliable. The
round ones could be attached for my dive planes and a strip type would work on
the rudder linkage. Very good find. Thanks for that.
