Economy is the distance travelled per un it of
fuel used. The Fishfinder calcul ates this using
the fuel used and boat speed (water spe ed or
GPS speed - which ever is selected as th e speed
source – see section 3-3 Setup > Fuel).
The bigger this number, the better the f uel
economy. Adjust the throttle and trim to
achieve the best fuel economy.

speed source, calibration of the boa t speed
measurement is essential for an accurate f uel
economy reading – see section 3- 8 Setup >
Calibrate.
