How-to: NMEA 2k and Helix 7 in-dash install - Part 3

[@toddweaver6064]

I thought you got data in part 2 I have a helix 9 g3n with a mercury 150 pro xs and am interested in installing nmea2k for engine hours and water pressure mainly any advice is this possible

I got some data in part 2, but not all the data I wanted. Engine hours should come over automatically. Water pressure depends. For example, on my SHO I have to add a water pressure sensor. Not sure about a Merc.
