Add together the two figures you have written down, to calculate the amount of fuel now in the tank. Press one or more times until the Setup menu is displayed, then select Fuel. Set Remaining to the amount of fuel that you calculated was now in the tank. 2 Note: Underfloor fuel tanks are often difficult to refill to the same level twice, due to air pockets. With underfloor fuel tanks: Trim the boat to the same angle in the water each time you follow procedure A. Mostly use procedure B below when adding fuel, but completely fill the tank and follow procedure A about every tenth time you add fuel. Note: If you follow procedure B every time you add fuel, then a small error will accumulate, because it is hard to measure exactly how much fuel you add. To avoid this, completely fill the tank and follow procedure A about every tenth time you add fuel. C When you remove fuel Repeat procedure B, but subtract the fuel you have removed from the original amount of fuel in the tank to calculate the amount of fuel now in the tank. 46 Northstar Explorer 650 Installation and Operation Manual 12-2 Fuel display Fuel display without engine RPM To go to the Fuel display, press , select Other, then select Fuel.

Speed If the Explorer has both GPS and paddlewheel speed available then you can select which to use. The choice affects the calculated Range and Economy (see section 17-5 Speed source). If the Explorer uses a paddlewheel sensor to measure speed, then the speed must be accurately calibrated (to calibrate the Explorer paddlewheel, see section 17-11). The bigger this number, the better the fuel economy Range The estimated boat range at the current fuel flow.
