Damage to fishing transducer cables by trolling motors is a common occurrence. Once cut a transducer cable will allow water into the ground sheathing and cause image issues with your sonar images ! A simple solution is to remove the transducer from the trolling motor. The real question is how to do this while still have a easy to use system that does not take up a lot of space at the bow of a boat.
Fighting to mount a transducer on a Terrova, iPilot, or even Xi5 trolling motors is near impossible. The trolling motor companies are in the business of trolling motors - not taking care of transducers and transducer cables. Bowducer assemblies mount only the transducer at the end of a downrod. The cable runs through the downrod making the system easy and compact.
A Bow-Ducer Outrigger mounting assembly:
The bowducer assembly is a simple cup using a special taper to hold the fishing transducer, which is typically mounted on a telescoping downrod, securely. Because of the taper used, the bowducer downrod will not drop through the cup and is very securely held when a side load (water) is placed on the transducer.
When scanning with a transducer, the downrod is easily turned in the cup. It remains stable and provides excellent imaging.
