New lowrance help needed

[NootkaFisher]

my wife just bought me a new lowrance hook7 chart plotter/fish finder to replace my old LC25X (she's awesome!). on the old one I have a nmea2000 bus currently set up with a fuel flow monitor on it. I would like to be able to switch it to the new plotter but I don't know if I can. The manual doesn't mention anything about nmea2000 but does say a very limited amount about nmea0183 and the I need an optional power plug to use it. I went to the store where she bought it but they knew nothing other than how to take her money.
Does anyone know if I can hook up my old fuel monitor?
Also, does anyone know if my 2014 Suzuki 140 can be connected to this plotter?
Many thanks for any info.

Does the unit have a sticker on the back near any of the inputs that indicate NMEA 2000? Some units aren't.

No. One says sonar and the other is pwr.

no nmea200 on hook series, there stipped down versions of HDS. old NMEA 0183 option for ais, etc but requires optional power cord. i think lowrance wanted to make an afordable chirp display for people who do not want all the bells and whistles.
