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).
10-3 When you add or remove fuel
When you add or remove fuel, you must tell
the TRACKER, otherwise the fuel data will be
meaningless.
A When you completely fill a tank
Go to the fuel display and press .
Then:
On a single-tank boat, select Fill tank.
On a multi-tank boat, select Fill tank,
then select the tank you have filled.
Note: Underfloor fuel tanks are often difficult
to refill to the same level twice, due to air
pockets.
With underfloor fuel tanks:
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
and follow procedure A about every tenth
time you add fuel.
B When you part fill a tank
1 Add fuel to a tank and write down how
much fuel you add.
2 From the Fuel display, press and
select Add fuel.
3 On a multi-tank boat, select the tank that
you have added fuel to.

that you added.
