I removed an old transducer tonight and will put the new ducer in the same spot after I drill a larger hole. The hull thickness in the location is about 1/4 inch. Is this thickness about right for the 20s? The hole is about 18 inches forward of the stern starboard side of keel by about 6 inches. The old ducer was so old the wire had either rotted off or been cut at some point. Any one recognize the make of transducer and its approx age. There was a transom mount ducer which was being used when I bought it.
