This has been a on going issue and I’m looking for a comparison for further troubleshooting.
-2021 Caracal Atlas J Plate
-Garmin Echomap Ultra 106sv at helm/126sv bow
-GT36UHD Atlas mounted/GT8HW thru hull
-Garmin Force with 3-1 transducer
-Transducer saver mount on the starboard side of Atlas
-Mercury 225 4s
#1 issue surface straight line interference starboard side
#Troubleshooting to date:
-Boat level position in the water with average load established
-Weight added to simulate average load fuel and gear
#Adjustments
-Transducer leveled front to back and port to starboard at 3mph
#Water test with these adjustments cleaned up the fuze on the starboard surface but no change on the port side.
#Adjustment 2
-Added a 1”x1” tube shim to lower Transducer to give additional clearance from the atlas plate
#Water test after shimmed same results still port side surface interference overall image very good, but the surface straight line interference is very annoying. I have cut power off accessories to test, plate and trim adjustments, speed and unit sensitivity adjustments and no difference. I’m thinking the J plate or my transducer position in relation to the plate is the problem. Looking for any input that may help with troubleshooting this issue.
TIA Wayne
