Fuel functions and display14
The Fuel functions require optional petrol/gasoline or
SmartCraft fuel sensors to be installed and set up.
13-1 What the fuel computer does
Each engine has a ow sensor installed to measure the
engine’s fuel ow.
The NX40/45 use these ows, together with boat speed
and engine RPM if available to estimate the fuel remaining
in the tank(s), fuel used, range and fuel economy. This
data is shown on the fuel display.
You can:
display the fuel used during a trip.•
set low fuel alarms.•
make fuel consumption curves - graphs of fuel •
consumption and boat speed as a function of engine
RPM - to monitor and optimize boat performance.
