67Northstar Explorer 657 Installation and Operation Manual
Source
Select the fuel flow sensors to use if the boat has
more than one set of fuel sensors. Normally select
Auto.
Num engines
Set the number of engines, or select 0 to disable
the fuel functions. If there are two engines they are
called port and starboard.
Num tanks
Set the number of fuel tanks. If there are two tanks
they are called port and starboard.
Setup engines
If the boat has more than one engine, select Engine
and select each engine in turn.
For the selected engine, you can enter:
From tank: The fuel tank the engine is connected to.
Flow filter: Most engines do not draw fuel from
the tank at a steady rate. To give a stable fuel flow
reading, the TRACKER calculates the flow by taking
several measurements and averaging them. Use the
Flow filter to set the period over which the fuel flow
is averaged.
The Flow filter can be set from 0 to 30 seconds. Use
the lowest value which gives a stable flow.Usually
a value of 5 to 10 seconds will give a satisfactory
result for two-stroke carburettor engines. Fuel
injected or four-stroke engines may require a larger
value.
This setting affects the Fuel flow and Fuel economy
reading on the Fuel window but it does not affect
the Fuel used reading.
Setup tanks
If the boat has more than one tank, select Tank and
select each tank in turn.
For the selected tank, you can enter:
Add fuel, Fill tank, Set remaining:
See section 12-3.
Tank alarm: See section 12-4.
Tank size: The tank capacity. Northstar
recommends measuring tank size by draining
the fuel tank, filling it to capacity and using the
fuel dispenser’s reading. Beware of air pockets,
especially in underfloor tanks.
Fuel consumption curve
See section 10-6.

If both water speed and ground speed are available,
select which to use for fuel calculations (see section
10-5-1).
