the Clear Used command.
Remaining

Flow
The fuel consumption per hour. For twin engine
installations, the fuel flow for each engine is
shown separately. This is useful for checking that
both engines are under the same load.
Speed
If the Explorer 538/538i 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 538/538i uses a paddlewheel
sensor to measure speed, then the speed must
be accurately calibrated.
Economy
The the distance travelled per unit of fuel used.
The bigger this number, the better the fuel
economy. Adjust the throttle and trim to achieve
the best economy.
Range
The estimated boat range at the current fuel flow.
5 Set Remaining to the amount of fuel that
you calculated was now in the tank.
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.
