Hard to tell from the low-res picture but it looks like you are getting most of the left Si sonar blocked by something.  Try trimming up your motor as high as you can and see if that helps.

Yes that is reflection from the bottom of your motor bracket or your Jack plate which ever one
you have. take a piece of metal fill in the opening between the sides and your interference will
disappear.Lowering your transducer will help.Or buy a holeshot plate that also will work.  Gary
