How to Mount a Transducer on a Boat's Bow

Whether you're looking for fish, or trying to navigate unfamiliar waters safely, the use of a depth finder/fish finder unit can be very beneficial. Fish and depth finders use a device called a transducer that uses echolocation to identify objects under the water. The transducer's signals actually bounce off the underwater objects and are displayed on the screen of the device. Transducers are commonly mounted on the bow, or front, of the boat to a trolling motor. The transducer should be parallel to the top of the water.

      Place the transducer bracket on the lower shaft of the trolling motor, positioned away from the propeller.

    • 2

      Insert the nut through the transducer bracket and tighten it down with the nut driver.

    • 3

      Slide the transducer onto the transducer bracket. Use a marine epoxy to help fasten the transducer onto the bracket.

    • 4

      Wrap the cable that runs from the transducer up the length of the trolling motor's shaft and use plastic ties to secure the cable to the shaft.

    • 5

      Plug the end of the transducer cable onto the depth or fish finder mounted on the bow.
