(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.
