Are you having this problem in calm water?
I know the slighest bit of water movement causes it to fluctuate. I do not rely on the
fuel guage. I know I should get around 4.5 mpg on average. So I feel comfortable
using 40-45 miles on 10 gallons. I keep up with the odometer. I have measured my
gps against the yamaha digital components & its so close that I feel comfortable
with those readings.
