Hello All,
After ~ 8 - 10 hrs over 2 weeks installing 898c si, I got out on the water. Unfortunately I did not take others advice and leave poles at home. Way to much going on. Using a transducer plate on transom was the way to go, just during the install I adjusted location 4 times. Once location, 3 times elevation, even with slots on transducer bracket. The transducer view clears everything, motor needs some up trim. I will post pic's.
I am able trim up motor slightly to side image to left. Over 4-6 mph I loose the half the left side. I am less than the 18" recommend way from center line of prop. Adrift or with trolling motor I have pretty good images to 120' on both sides. The strange thing is the depth reading would get real bouncy. In 8 fow, reading goes from 3 to 20, or more. This is still with side images coming in fine. I have an older Lowerance to the right and above 898 trans. I shut this off but still had the bouncing in depth reading. Good side images. I may be wrong but it seemed like if the TM was pulling the boat straight the wash coming out the back woould cause bouncing in depth reading. Anyways there are so many settings and options, I need to keep a note book with me.
I am happy with purchase, I know I have lots to learn on adjustments. The depth bouncing I am sure will work its way out. I am getting ready for an out of state trip, so I don't think I will mess with physical location.
I will get some pic's of transducer up soon and some pic's from the fishing trip.

Jim. 2 to 3 mph for best use any above that and quality drops off very fast to unusable.
Try setting the depth manually this has worked for me.
Good luck and enjoy.

Jimliner:
The depth bouncing could be caused by trolling motor interference and/or main
motor interference and/or some other electrical device(s) on your boat.
There's an easy way to tell. Cut off all motors and all other electrical devices and just drift around and see if the depth holds steady. Then turn the motor(s) and devices back on and see if there is a change.
If you are having interference issues, then get a small marine battery just for the sonar.
That should cure it.
Another tip is to set your MAX DEPTH reading as close to the actual depth of the water you
are fishing. Maybe 5 or 10 feet deeper.
I think it was XSilmarilSx that found out that you could get better SI images/ping rates by
doing this.
Good Luck.
