My new unit seemed fine for about a week and then the side scan starts to look very distorted for a few seconds then the side scan screen just goes blank..... When I raise the engine, nothing changes but when I rev it in reverse it seem to get a few seconds of distorted data and then back to a blank screen. To me it seem like water intrusion and then cuts out and sometimes for no reason it will just start working again... for a bit.
Does anyone recognize this issue?
Thx
Adam
