Are there significant differences between transom-mount and in-hull transducers?
Is my problem in the wiring (connector) or in the location of the transducer?
Background - My CD-22 came with a Standard Horizon DS-35 Depth Sounder mounted on the port-side cockpit bulkhead. The transducer was mounted on the transom which, to my mind, was not very aesthetically pleasing and only seemed to be actually in the water when someone was sitting in the cockpit. But it at least worked.
I decided to move the transducer from the transom and mount it inside the hull, on the port-side just aft of the quarter berth in epoxy resin. (Yeah, I know, shoulda, coulda, woulda . . .)

In the process of pulling the transducer cable the RCA-type connector at the end of the cable became stuck and I ended up cutting the cable and soldering on a new conenctor. At first the only indication I got was "--.-". I checked the connector and the shield and conductor were making contact, so I re-soldered the connection, ensuring the two were not shorted together. Now the only indication I get is "11.5", regardless of the actual depth.
I went thru the all the steps of programming the unit but nothing seems to work properly.
I've searched for a replacement in-hull transducer (Standard Horizon DST-55) but it apparently is out of production and no longer available. I found one for $89.99 on one web site, but that's almost the cost of complete unit w/transducer.
