I am wanting to connect my 2018 Yamaha 150 SHO to my Humminbird Helix 12. I have no experience with NMEA and this is confusing the crap out of me. Can anyone explain exactly what I need? From researching I believe it may be the below but not sure.
Humminbird 408390-1 NMEA2000 Black Box with Ethernet Connection
Lowrance 000-0120-37 Yamaha Engine Interface Cable
NMEA Network Starter Kit, Model 124-69
Appreciate any help with this.
