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
measurement is essential for an accurate fuel
economy reading – see section 3-8 Setup >
