This is a CAD model and component drawings for our mounting system. The top baseplate will be screwed into a 2x8 that spans the end of the raceway. The sliding collar is secured with a thumb screw and is removable so it can be used to adjust depth and remove the transducer from the water. The transducer bracket is sized to fit the diameter of our transducer (modelled to the top left of the baseplate) and is also tightened with a thumb screw, so no tools are needed to install and remove the hardware.
