Location: Ottawa Lake, MI | So I am installing a new depth finder in the front of the boat and the transducer will be off the back. Putting the transducer on the trolling motor is not a option. My boat is a 18 foot Lund and the depth finder is a lowerance. The transducer cord is 20 ft long but after running it under the floor the cord isn't long enough to make it to where I need it to be. Is there anyway I can make that cord longer? Can I splice 2 together? |

| I would get a shoot thru hull transducer |

You can splice I've been told it changes the puls length and not a true reading .its just what I've been told.very fine wires and they must not touch each other.theres a center wire with a coating and an outer very fine wire.maybe not much help |

| You should be able to buy an extension from the manufacturer. |

Location: Ottawa Lake, MI | The trolling motor is wireless motorguide. There is just no way to run the transducer cord down the shaft. It's hard to explain why. Im not sure what a shoot thru hull transducer is? Does it work on a aluminum hull? Where do you mount that at? |

| Run it down the shaft and over the pivot, tape the cord on top and bottom of shaft. The shaft will still slide thru, make sure to run the transducer cord thru the coils on the cord of your motor. It will look much cleaner |

| I believe shoot-thru hull transducers are only applicable for fiberglass hulls. I would say the smartest and easiest thing to do is get an extension, as already mentioned. |

+1 what clint said....I ran one of these for years with a transducer mounted on it, tie the cable just under the trolling motor head, run through the coils and out to transducer. Leave slack to allow deploying trolling motor and all should be good. Only thing to watch was I only had enough slack to turn head once, so had to keep an eye on not turning motor head more than once and pulling the cable. |

If you have two newer Lowrance units you can run the rear transducer to the helm unit, then just use an Ethernet cable to connect the 2 units together and you will have the same readings on both. I'm no expert but this would be the easiest/best setup I can think of to have a correctly mounted rear transducer for the bow.
Assuming you have a helm unit... and if you don't hook it up as above or below the bow electric as recommended, you would then have to have two transducers mounted on the transom with the bow having some kind of an "extension cord". That would be hokey and a good chance of having "crosstalk" between the two transducers.

Location: menasha wi 54952 | If you must you can splice the transducer cable. Not really a big deal if you have the right material. When you cut it you will see it looks like a coaxial cable. Mesh cable on the outside and shielded cable in the middle. Use similar material and you wont have any problems. Just make sure you seal it with shrink wrap and water tight silicon. The easiest way would be get the extension.
You can easily mount your transducer to this trolling motor. Like Lars stated above, utilize the coiled trolling motor cable and the head before running to the motor. One thing to add is a eye hook to the base where it hangs off the front of the boat. Very easy to do. Remove the furthest most base cover screw from the trolling motor. Take it to your local hardware store and get a stainless eye hook with the same thread pattern. Tighten eye hook into cover where you removed the screw. Open hook with two pliers and slide in transducer cable. Close hook with tools. Now you have a permanent loop for cable to slide through and take up enough slack for easy deployment. |

Good point mreiter, I-bolt is a good idea. I forgot to mention i used a ziptie through the trolling motor side cover and left it loose and the cable would slide through that. Never had any problems with it. |

I agree that mounting the transducer to the electric would be the best option, particularly for an accurate depth at the bow while casting… but he said it’s not possible. It almost has to be possible though, maybe one of you guys could post a picture
Otherwise, I would be leery of having two transducers mounted closely together on the transom running to two different units because of possible interference/crosstalk. Unless of course there is no helm unit involved, but that would be pretty unconventional.

| I ran two transducer off the back on my old boat, but didn't like always over shooting structure due to getting late info at the front, so i moved it to the trolling motor on my motorguide. That was my prefference, not much help with making cord longer though. I will look at some pictures of my old boat and see if I can find a good picture if that would help. |

Making a transducer cord longer?
