Fuel Tanks
NOTE:
Setting the fuel tank capacity and calibrating fuel level sensor are
only necessary if an optional speedometer gauge and sensor interface mod-
ule (SIM) are present.
Tank capacity is entered on the tachometer gauge and is an important com-
ponent of fuel management. Fuel management is a function of the optional
I-Command
speedometer gauge.
When setting fuel tank capacity, it is recommended to factor out a portion as
unuseable fuel.
Unuseable Fuel —
Due to the boat’s fuel tank
placement, consider a percentage of the tank’s
fuel capacity as unuseable fuel. This is fuel
that will take up space in the fuel tank, but can-
not be reached by the fuel pick-up.
To obtain the most accurate fuel management
readings, tank capacity should be confirmed.
GOOD
— Fuel management based on fuel sensor’s default factory settings.
BETTER
— Fuel management based on inputting fuel tank capacity and the
fuel sensor’s default factory settings.
BEST
— Fuel management based on inputting fuel tank capacity and per-
forming fuel sensor calibration.
IMPORTANT:
It is recommended the fuel tank size be verified. Some tanks
have larger or smaller capacities than posted, and many factors such as
unuseable fuel, tank positioning, mounting, and angle must be considered to
get an accurate capacity. The boat should be oriented in normal operating
position.
Setting fuel tank capacity —
Enter the System Set-up screen, and using
the UP / DOWN buttons, scroll to Fuel Tank and press ENTER. The Set-up
Fuel Tanks screen appears. Press the UP / DOWN buttons to toggle
between tank 1 or 2. Press ENTER to select tank 1. “SET” appears in the
upper right corner. Input the tank capacity by continually pressing the UP
button until reaching the desired tank capacity. Press ENTER to set the tank
capacity.
