Range
The estimated boat range at the current fuel flow. The value can depend on the type of speed
sensor (see section 10-5).
Economy
The distance travelled per unit of fuel used. The value can depend on the type of speed sensor
(see section 10-5). The larger the value, the better the fuel economy. Adjust the throttle and trim to
achieve the best economy.
Fuel consumption curve
A graph of fuel consumption and boat speed as a function of engine RPM. Use the curve to monitor
and optimise boat performance (see section 10-6).

When you add or remove fuel, you must tell
the TRACKER, otherwise the fuel data will be
meaningless.

Go to the fuel display and press
.
Then:
On a single-tank boat, select Fill tank.

pockets.

Trim the boat to the same angle in the
water each time you follow procedure A.
Mostly use procedure B below when
adding fuel, but completely fill the tank

time you add fuel.

1 Add fuel to a tank and write down how
much fuel you add.
2 From the Fuel display, press and
select Add fuel.
