Default Help..Getting lines on Garmin 7612xsv with B175HW Chirp?

installed the unit and transducer beginning of summer and have been offshore canyon fishing 4 times. Iím getting these lines while running and canít figure out if there is a problem or Iím losing bottom at speed. Transducer is mounted aft a foot up from center on Grady 330 Express. There is only clean water in front of it. Hereís some photos. Any idea what could be causing this?

looks like you are getting noise from engines running, do you have Suzuki outboards? try to connect MFD to a seperate battery.

If you don’t get that at lower speeds. Than likely turbulence. I get the same line when I am doing 30 or above 2000 RPM

Read above link. If you get that at lower speeds, than maybe from engine and do what I did

Turn the interference off to see what its really doing. Mine looked great with it on high but was not marking any fish

This is aeration under the transducer.
At that speed, I would not worry much because it's minimal and still has a solid lock on the bottom,
