I have a 1197 unit on the bow attached to a 101 terrova with ipilot. After two years of working fine, I now have erratic depth and temperature readings whenever I step on the throttle to turn the prop on the trolling motor. When I release the throttle, the depth readings go back to normal however the temp reading never recovers unless I turn the unit off and back on again. Issue still exists if the other 1197SI I have on the console is turned off.
Any advice on how to most easily solve this issue? Do I replace my 101?
