NMEA 2000 Smartcraft Gateway
Since the lightning strike im upgrading to the garmin gpsmap 741xs due to the lack of real estate on my dash, but it is definitely a huge upgrade to the Lowrance 2400 thing that's there now. The garmin is NMEA 2000 compatible. Has anyone had experience with a 2003 5.0 MPI. The motors are smartcraft, however all of my gauges are analog and extremely unreliable. If my research is correct... BIG IF... I can purchase the Mercury Twin Engine Gateway for around $300, hook it into the NMEA 2000 network and simple as that I can view all of the engine information on the chartplotter. I believe this will show fuel flow (most important), Engine RPM, Oil/Water Pressure, Temperature and maybe some others too. If this works I will probably replace the entire current gauge panel and install a couple Garmin GMI 10's and do away with all of those gauges.
Has anyone had any experience with the 2003 MPI and the Mercury Gateway. Any incite would be greatly appreciated

I have been studying this stuff a lot lately. Don't take this for the gospel but I believe the SC1000 has a NMEA 2000 plug on it. Since everything is in the dash I think all you need is to build a small network with a cable coming from the gauge to a T connector connected to another T Connecter Power Supply connected to another T Connector with a cable going to your NMEA 2000 chart plotter then a male a female termination cap. Wouldn't cost very much at all probably less than $75
If that Makes any sense... lol there are lots of videos on you tube that explain the network. If I were to do the above connection on my garmin to the SC1000. An Icon would automatically pop up on the home screen that says gauges and I could view all supplied engine data on the chart plotter. Just that simple.
Wow!!! Thanks
any chance you have a diagram of how all of this is connected?
When I connect the gateway to my N2K network, I can see engine data on my displays. However, the gateway sends a bogus rudder position signal that causes my autopilot to go unstable. Apparently it's a known problem with how the Raymarine C80 handles duplicate data messages. There's no way to tell the gateway not to send a rudder signal, and no way to tell the Raymarine gear to ignore it.
For now, my only workaround is to disconnect the gateway.
