Buzzarde Posted July 2, 2019 Report Share Posted July 2, 2019 I have a 2018 24' pathfinder with 104 hours. It came with a yamaha digital engine readout which includes the fuel level bar graph. On several trips I have noticed my fuel indication will drop from 4 bars down to 1 bar in a blink! man will that get your focus! The last time it had the last bar blinking! Im not sure whats going on? Could be a bad sending unit or The system has not been calibrated? Anyone elts had this happen? Quote Link to comment Share on other sites More sharing options...
Bamaskeet Posted July 2, 2019 Report Share Posted July 2, 2019 I don’t have any suggestions to fix your problem but I have had good luck using my odometer to determine fuel usage. I get 4 mpg in mixed use. I zero it out during every fill up. It’s scary accurate. Quote Link to comment Share on other sites More sharing options...
Bruce J Posted July 3, 2019 Report Share Posted July 3, 2019 On my 2400 and on my Maverick HPX-T the gas gauge consistently underestimates the gas, and both drop quickly once under half a tank. Of course rule #1 of boat ownership is never to trust the gas gauge. Never. The best thing to do is connect your engine data through a NMEA 2000 backbone and then to your multi-display, Garmin or whatever. Once you get that calibrated it will calculate your fuel burn very accurately and subtract it from your tank capacity to show a much more accurate fuel level.
