10 Fuel functions and display

The Fuel functions require optional petrol/gasoline, diesel or SmartCraft fuel sensors to be installed
and set up.

Each engine has a flow sensor installed to
measure the engine’s fuel flow.
The TRACKER uses these flows, 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
displayed on the fuel display (see section 10-2).
You can:

display the fuel used during a trip

(seesection 10-2)

set low fuel alarms (see section 10-4)
make fuel consumption curves - graphs

of fuel consumption and boat speed as a
function of engine RPM - to monitor and
optimise boat performance.
(see section 10-6)

10-2 Fuel display

To go to the Fuel display, press

, select

Other, then select Fuel.
The display differs according to the number of
engines and tanks. If engine RPM is available
and if you have made and selected a Fuel
Consumption Curve (see section 10-6), press

to switch between a Summary or a Fuel

curve display.

The Fuel display shows

Speed
To select a boat speed sensor, see section 10-5-1.
RPM (if available)
If engine RPM is not available, the display
shows depth.
Remaining
The fuel remaining in the tank(s) is shown as a
vertical gauge on the right of the display. The
height of the yellow bar(s) show how much fuel
remains in the tank(s). If you have set a low fuel
alarm (see section 10-4), a red bar shows the
level at which the alarm will trigger. If there are
two tanks, the left bar shows the port tank, the
right bar shows the starboard tank.

10-1 What the fuel computer does

Used
The fuel used during a trip. On a multi-engine
boat, the data for the port engine is on the left
of the display.
When you want to start measuring how much
fuel is used, go to the Fuel display and:

In a single engine boat, press

and

select

Clear used.

In a multi-engine boat, the fuel used by

each engine and the total fuel used are

shown. Press

, select

Clear used

and select:

Port or Starboard to clear the fuel used

by one engine

Both to clear the total fuel used.

Fuel flow
The fuel flow for the engine(s). On a multi
engine boat, the data for the port engine is on
the left of the display. Use the flows to check
the load of each engine.

CAUTION

DANGER

WARNING

To ensure the fuel data is accurate:

When you add or remove fuel from a

tank, tell the TRACKER (see section 10-3)

If the boat has petrol/gasoline sensors,

calibrate them during installation or if
the fuel readings seem inaccurate (see
section 10-7)

Choose an appropriate type of boat

speed sensor to calculate economy,
range and the fuel consumption curve
(see section 10-5)

If the boat uses a paddlewheel sensor

to measure speed, calibrate it during
installation or if the speed readings
seem inaccurate.
