Yacht Devices Tank Level adapter install in Boat Talk Posted May 3, 2020 7 hours ago, quattrospeed said: Wow, I’m a long time lurker here... 2007 290 SIG (pictured) and I had no idea this was even possible. Am I reading this right? I can connected my mercruiser engine data and gauges to my nema2000 device? In this case Garmin 942? I would definitely pay for guidance with this. I would this so too! I too have a 290 but 2011 model and Volvos. I would suggest a bigger GPS or at lest a 2nd one if you going to display engine data too.
