Mercury EFI to Lowrance Plotter connection?

[diver 1]

I have a 2011 Mercury 100HP EFi 4 stroke that I'd like to connect to my Lowrance plotter either through NMEA 0183 or NMEA 2000. I've read some American forums that seem to talk about a Mercury gateway connector but are there any other ways

Also does anyone have a used mercury gateway connector thing for sale in the UK new or used??

I would fit a Smart craft gauge but I'm very short on console space on this rib

Thanks for any help.
