Anything to troubleshoot for this? Initially started losing depth at speed, now it's all but gone, even at idle. Fish finder still works and reads depth in that mode but structure scan doesn't seem to return correctly either. When on the chart view with the instrument panel up on right side that reads speed and track direction, the depth mostly stays blank now, and that is when I really need depth up, when running into the flats. Transducer is located on the inboard side of the starboard sponson. It's in the water on plane as well as at idle.
