Garmin GT56 Transducer installation on 2022 Sea Doo Switch boat pontoon

I installed a Garmin GT56 transducer on my 2022 Sea Doo Switch 18’ 230hp pontoon. This should be similar for the 18’ and 21’ models as well. My video is focused on the routing of the wiring inside of the boat up to the Garmin. Sorry for the instability of my video at times. Still working out some camera challenges with my recordings.

Note:
Hole size for the transducer mounting screws are 5/32
Hole size for the cable routing 90 degree cover screws are 1/8”
