Mine has the (older) inline paddlewheel senders back near the fuel tank. (they work YAY!!) Pretty sure my motors are pre - NMEA2000 and I have heard (but cannot confirm) that the newer Yamaha has the fuel usage sender under the cowl.
I guess I was wondering if there was a trick (using diodes or something) to be able to power the fuel management meter off of both gauges, but I'm happy as a clam now that it's working and showing both engines. I just wanted to be sure that the design is consistent with how I see them working.
Thanks, guys.
