start measuring how much fuel is used, press
SETUP
, select Fuel and select Clear used.
Remaining
The amount of fuel remaining in the tank.
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 Instrument 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 Instrument uses a paddlewheel sensor
to measure speed, then the speed must
be accurately calibrated (to calibrate the
Instrument paddlewheel, see section 17-11).
Consumption
The fuel used per unit of distance travelled.
The smaller this number, the better the fuel
economy. Adjust the throttle and trim to
achieve the lowest consumption.
Economy
Economy is the distance travelled per unit of
fuel used. The Instrument calculates this from
the boat speed and fuel used. The bigger this
number, the better the fuel economy
Range
The estimated boat range at the current
fuel flow.
