sounds like an interferance problem to me... engine electrical noise is
messing up the depthsounder. The noise could be coming down the DC
power leads, in which case either a capacitor or a ferrite bead or both
will fix the problem. The noise could also be entering directly as
radio waves, in which case you must stop it at the source.
I am assuming you have a gas engine, and an inboard. Do yo have
resistor plugs? Supression spark plug wires? Is there a capacitor on
the alternator output?
