Garmin J1939 to Yamaha Engine Bus Adapter Cable

Usually in Stock - Ships the same day. Call us to confirm stock if you're in a hurry.



This cable unlocks a world of goodies for Yamaha engine owners. It utilises the J1939 port on the Garmin 7400 and  8400 series screens so is not NMEA2000, hence it is not compatible with earlier models (including early 7400 series units), nor echomap models or 952/752 models.


This cable connects your J1939 equipped GPSMAP 7400/8400 series chartplotter directly to the Yamaha engine bus multi-hub. This enables Yamaha’s custom touchscreen engine interface to your Garmin Touchscreen
