So I posted the other day on mercury's mercmonitor and finaly got it in today, 2 hours later it works. If you don't know what it is it is a single digital guage that taps into your ECM on the motor. There's diferent levels of info that are dependent on your motor. This guage is a speedo, tach, batt, oil presure, water presure (will tell you exactly what psi your water presure is real time) fuel monitor, oil res monitor, etc...... you'll have to read for everything it does, but the cooledst thing is the alarm feature. Now when the alarm goes off it tells you what for. also any computer fent alarm such as oil level getting low is displayed. This is a must havefor most of yall who discover it. Like I said do some reading. there's diferent level guages. I got the level 2 with smart tow. You'll have to research smart tow also. My boats an 05 and I think it will work on 2000 on up.
