Our Simrad radar began working intermittently early this summer. My boat is 2014 OC 45.. It stopped working altogether in July everything was checked. My dealer hooked up another scanner and cable and all worked He took apart the radome and found 2 inches of water in the unit. The dome had never been touched. He said the seal was intact. He thinks it may have been due to a driving rain. We sail on Lake Michigan out of South Haven. We have had some severe storms this year. Has this ever happened to anyone else? I'm probably going to have to get a new scanner and cable. Kind of pricey!
