Disabling the fuel management software will allow the fuel gauge to
read fuel levels directly from the fuel sensor on the fuel tank. Should
operators wish to turn fuel management back on, the easiest way
to do so requires enabling fuel management on the User Settings
page, filling the boat with fuel and inputting FULL on the fuel entry
screen.
When low fuel warning is displayed immediately empty all ballast
tanks and proceed to the nearest fueling station.
button to adjust to the correct amount of fuel. Use a positive value
if more fuel needs to be entered, or use a negative value if too much
fuel was entered.
When the fuel management system senses that fuel is getting low
it will display a low fuel warning on the screen. When this warning is
displayed, the boat will be able to run unballasted for approximately
20 minutes before running out of fuel. Empty all ballast tanks and
immediately proceed to a fueling station before any further activity.
Continuing to operate the boat with low fuel levels could leave users
stranded offshore.
If an operator has inaccurately or mistakenly entered the fuel level,
there is a sensor in the fuel tank that will override the entered fuel
level when it senses low fuel. To avoid false readings, the sensor will
only override the fuel management system when it detects a low
fuel level for more than 30 seconds with the engine operating at
less than 900 RPM.
To disable the fuel management software and rely on traditional
fuel gauge readings:
• Push the Menu Hot Key on the 450NT screen.
• Scroll to User Settings.
• On the User Settings page select either ENABLE or DISABLE
under Fuel Management.
