Instruments and indicators31 The fuel flow meter displays gallons/hour orliters/hour according to operator prefer-ence. Select the desired units of measure-ment by setting the selector switch on theback of the gauge during installation. The fuel consumption meter and fuel econ-omy meter will indicate the same unit ofmeasurement.Fuel flow readings are not accurate when theengine is operating under about 1300 r/min.As the fuel pump cycles on and off, the displayindicates either no fuel flow or higher flow thanthe actual average use.Dual engine users: the fuel flow meter candisplay the fuel flow of either or both engines.To change the fuel flow display, press the“ ” (set) button repeatedly until the gaugedisplays “ ” (for fuel flow to the starboard en-gine only), “ ” (for fuel flow to the port engineonly), or “ ” (for total fuel flow both engines).EMU36090Fuel consumption meter / Fuel econo-my meter / Twin engine speed syn-chronizerThe display shows either the fuel consump-tion meter, the fuel economy meter, or thetwin engine synchronizer.To change the display, press the “ ”(mode) button repeatedly until the indicator onthe face of the gauge points to “ ” (fuel con-sumption meter), “ ” (fuel economymeter), or “ ” (twin engine speed syn-chronizer).EMU26761Fuel consumption meterThis gauge displays the total amount of fuelconsumed since the gauge was last reset.To reset the total fuel consumption meter tozero, press the “ ” (set) and “ ” (mode)buttons at the same time.EMU26771Fuel economyThis gauge displays the approximate distanceper liter or gallon when cruising.1.
