Claim 11:
12. A fuel management system including a fuel pump to control remaining amounts of fuel in a plurality of fuel tanks mounted on a hull of a marine vessel, the fuel management system comprising:
a management tank connected to an engine;
a plurality of first fuel flow channels corresponding to the plurality of fuel tanks to connect the plurality of fuel tanks to an upstream side of the fuel pump;
a plurality of second fuel flow channels corresponding to the plurality of fuel tanks to connect the plurality of fuel tanks to a downstream side of the fuel pump;
a third fuel flow channel to connect the management tank to the upstream side of the fuel pump;
a fourth fuel flow channel to connect the management tank to the downstream side of the fuel pump; and
a controller configured or programmed to transfer fuel from the management tank to one fuel tank of the plurality of fuel tanks by the fuel pump; wherein
each of the plurality of fuel tanks includes a fuel sender;
the management tank includes a calibrated fuel sender; and
when transferring fuel from the management tank to the one fuel tank by the fuel pump, the controller is configured or programmed to perform a calibration of the fuel sender of the one fuel tank by using a change in an output value of the fuel sender of the one fuel tank and a change in an output value of the calibrated fuel sender.
