    Helix interference - sometimes

    Today I finally got me new rigged boat out on the water. I have a helix 12 si gen1 on the bow with the hdsi transducer on my fortrex. I’m showing interference in si and occasionally di depending on what speed the trolling motor is on. The higher I turn It the interference starts goin away. If I turn it on high there’s almost none.
    Anybody have a similar issue? And how did you solve it?
    Thanks
