A couple of months ago I bought a 1992 Four Winns Sundowner 195. There's a
Lowrance depth sounder installed. At slow speeds it works fine, but at speed,
it doesn't.

It does not start working when I return to slow speed.

I thought initially that there was some problem with the external location of
the transducer, but as near as I can tell, it's internal.

I'm thinking maybe it has come unglued from the hull. Before I go digging
around trying to find it, does anyone know where it's installed?
