Hello, I'm new to the forum, first post. I own a 2015 Nordic Heat with the Mercury Racking 520. My Livorsi gauge is throwing a fault 206 and 210. The 6 second beep, then off 6 seconds and back on for 6 seconds indicates it is severe. I'm being told that the Livorsi codes are different than the Mercury codes. Mercury 206 is Engine Overtemp and 210 is Engine RPM over recommended limit in neutral. When I started the boat on land, the throttle was up one notch so it revved for 2-3 seconds.
