[C320-list] Routing depth transducer cable

[Jerry Schrock]

Jack,  I just installed my new Raymarine speed transducer. I used the route through the port settee and instead of running through the panel I just went under the sink then underneath the stove. That may get you another few feet. You might also go straight through the bilge to save a few more. Use a fish tape to find a route. I Also read from Raymarine web site that you can splice wires without ill effect on the signal.
