Since OFC was quick to solve my prop nut woes, thought I'd try another issue! My finder (Lowrance elite 5) never seems to mark fish while the motor is running, only when drifting or when trolling motor is on. All the cables are wrapped snuggly together. Could this be the source of a problem or would that have nothing to do with it? Would it help if I put something between the fishfinder cable and all the other cables (ie put a rag or something in between?). I already tried adjusting ping speed and that didn't help. Last time out sometimes it didn't even read that well, would tell me I was in 2 feet when it was more like 30. Would be like that for a minute or 2, and then all of a sudden would start working again.
