I also have the Mercury NMEA2000 Gateway Part #8M0065208 that allows you to push the engine info out from the Smartcraft system to your NMEA2000 network and get the info onto your MFD. Works great, I used it to push the info to my Raymarine E95. The new Vesselview has a NMEA2000 connection built...
This is what I used on our last boat and it was great. If you go with the dark colors you will need to wear shoes to walk on it. this stays at least 30 degrees cooler than the dark colors.
