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 display but it

does not affect the

Fuel used

reading.

Fuel consumption curve

See section 10-3.

Speed source

If both paddlewheel sensor and GPS speeds are
available, select the source of speed readings
for fuel calculations. If there is a current or tide,
these speeds and the fuel calculation results will
be different.

Water speed:

Use paddlewheel sensor

speed (boat speed through the water). This
gives a more accurate value for Economy.

GPS:

Use GPS speed (boat speed relative

to land). This gives a more accurate value for
Range.
