That's already a replacement, and not the one that came with the boat.
Would you be able to explain how to test it, either describe it in detail or attach a sketch? I would hate to change it if I didn't need to.

Would you know why in "mtajpa" thread:

the old seader (like mine) does not measure correctly but the new one measures correctly, is it a different style, electronic compaired to mechanical slide?

Thanks, Steve
