Post of a list of your SI settings with a snap shot from your SI unit. I think this could be real helpful to everybody. Esp those who are new to SI. It took me a little time to get mine set up right and there still might be room for improvement.

Side View Frequency - 800 khz
Surface Clutter - 5 (this is default)
Switchfire - Clear
Fish ID - Off
Fish ID Sensitivity - 5

83 khz Sensitivity - 0
Noise Filter - Low
Transducer Selection - Hi Def SI
DI Beam Width - Medium
SI Sensitivity - 9
SI Enhance - Sensitivity 9, Contrast 10, Sharpness Low

In that last pic did you catch any of those? Just curios as what they were

I have a 798ci SI. I normally run the sensitivity on auto and the chart speed on 3.

Wilbur,
I thought those fish in the second pic were bass at first. I went back to that area with a Red Eye Shad, pig/jig, and spoon... As I was casting gar were rolling everywhere on the surface just in that area. I never got a bite so I wrote them off as gar.

If there have been no changes to your boat, those fuzzy looking lines could be air bubbles flowing off that side of your boat hull. Try shutting the main motor down and see if those lines go away or not. If they do than its air bubbles flowing off the boat hull. If they don’t than its something blocking a part of the Si sonar to that side.
