I got my coax from the universal sonar caught and cut it when I lifted the trolling motor up. I spliced them back together and now I get alot of interference on my back depth finder when the trolling motor is down in the water. I didn’t have any scheild to cover the wires with, would this cause the interference?
Try a small piece of aluminum foil taped over, around it.

Hope this helps you out, It is straight from Eagle electronics.
Cut the cable in a location that will place the splice in a protected area in the vessel. It should not be exposed to rain or spray, nor be allowed to lay in the Bilge or other area which will allow it to be submerged in water. If using a “heat shrink” insulating material, for either the center conductor connection, shield connection, overall splice, or all of the above, place over the cut ends now.
Carefully strip approximately 1” of the outer insulation or jacket from the ends to be spliced. Unwrap the shield and twist it as shown below.
Strip approximately 3/8” of the inner insulation (center conductor) from each end to be spliced.
Twist the center conductors of the two ends together, and then solder the connection. Use special care to allow full flow of solder without damaging or melting the insulator around the center conductors. This can result in a shorted connection and damage to the sounder. Wrap the solder joint in good quality electrical tape or heat shrink as appropriate.
Twist the shield wires together and solder this connection. Wrap a small piece of Aluminum Foil over the entire splice. Make certain the foil makes a good contact with the shield wires to prevent, reduce, or eliminate electrical noise or interference.
Finally wrap the entire splice with electrical tape or use the Heat shrink material previously installed to completely seal and insulate the splice connection. The transducer is now ready to use.
Take it too a authorized Minnkota repair shop and have the cabel replaced. That would be your best bet Jimbo.
trumar is correct, ive had to repair two of these and following these dirrections they work as good as new.

I have some really good alum tape that you can use if you want instead of the alum foil and tape. It should do the same job but stick better. We use it to mask off sensitive areas when welding. You can get it at an automotive supply store but it is quite expensive. I think the standard rolls are about 2.5 or 3″ wide
