On a Terrova with the newer models that have the lift assist, you can remove the assist spring setup ( which most people don’t need anyway ) mount Garmin transducer on motor and cable up grove in shaft. No cable management system needed. Couple of videos on YouTube about installing on Terrova. Most don’t like pedal. Mine hasn’t been hooked up in 6 years. Depends on how you fish but if you want or need pedal then Ultrex is way to go but then you get into cable management or separate mount. Most depends on how you fish.
