Have a 998c si on the console with transom mount transducer, splitter cable and XP 9 20 in hull. Depth does not read accurate. Have 858c di on bow with transducer on trolling motor. Can I switch these units to eliminate the unit itself? Just started having problems, had this set up for 2 years.
The 998 will read 3' for periods of time, then work properly for a while then back to 3'.
Thanks for any input.
