I just put a 24 volt Minn-Kota and a Garmin 73SV on my aluminum boat. Side image seems to do alright but noticed interference on my 2D view everytime the trolling motor is turned on. I may have this interference on DI too but the screen is a little dark on the DI to tell for sure. What can I try to get rid of this interference? For now the transducer is on the trolling motor.
