There are no options.
(See section 3-3 Setup > Fuel for information
about setting up the fuel values. If the number

Used
shows total fuel used since this was last
reset with the
Clear Used
command.
Remaining
shows the amount of fuel remaining
in the tank(s).
Flow
shows 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.
Economy
is the distance travelled per unit of
fuel used. The Fishfinder calculates this using
the fuel used and boat speed (water speed or
GPS speed - which ever is selected as the speed
source – see section 3-3 Setup > Fuel).
The bigger this number, the better the fuel
economy. Adjust the throttle and trim to achieve
the best fuel economy.
Note: when water speed is selected as the speed
source, calibration of the boat speed measure-
ment is essential for an accurate fuel economy
reading – see section 3-8 Setup > Calibrate.
5-6 Fuel display
When fishing among a school of fish and catch-

when that particular echo is seen at future times
on the fishfinder, it is likely to be the same fish
species.
