sort of on the ball there
the vessel view software "and display characteristics" are designed by navico "lowrance/simrad etc" hense why they look similar
and without the vessel view you will need a Mercury NMEA-smartcraft box "a couple hundred bucks from your local mercury dealer" which takes engine smartcraft data and runs it into nmea2k which can then run to your simrad backbone giving you data
IMO its always good havign one factory gauge at least.
