I am thinking of purchasing a HELIX next spring but wanted to find out if they are NMEA 2K compatible. I have an ONIX that was suppose to be but it would not show engine hours so I bought a Lowrance that does. I would like to eliminate the Lowrance but will not do so if the HELIX won't show me what I want. I have a 2015 Yamaha cabled to the Lowrance. Would I need to purchase something more for the HELIX to show engine information? All responses very appreciated. Thank you, Jim
