Hey guys, I dont have a merc monitor on my 08' 225 opti and was looking to either install the smart craft gauge or run the NMEA 2000 from my Onix to the engine. My apologies if this subject has been covered but I would appreciate some opinions on this topic. Id prefer not to spend a ton of $$ on the smartcraft if i can get similar info from the NMEA to my Onix for less money. Thanks guys
