Maybe someone can help. I have an 08' Fountain 35 lightning with a Livorsi depth guage that acts very erratic. It gives all crazy depths, 590ft, 99ft, 250ft...etc. has anyone had this problem? If so what was the issue?

Mine sounds the alarm everytime you come out of the water. I'm about to pull it out and put a clock in its spot

Is this when you are running, or at idle? I've never had a DF that worked above a fast idle on a step hull boat.

It's erratic even at idle. When I'm running the alarm rings like a bank robbery. Very annoying.
