After much valuable counsel, I decided to take on the job of installing the new depth sounder transducer and forget splicing the wire. And all went smoothly. It was much less difficult than anticipated. A key reason was some advise I received regarding the tube that carries the instrument wires to their housings above the companionway. This tube is about 1 1/4 inches in diameter and has a number of 90* bends. I squeezed 1/3 of a bottle of Dawn dish washing liquid into the tube at the highest point. The Dawn ran down the tube. I then used the old wire to pull through the new one. The Dawn acted as a great lubricant to make every thing go smoothly.
Thank again for all your input.
