Claim 10:
11. A fuel management system 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 fuel pump;
a fuel meter;
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 and the flow meter;
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 and the flow meter;
a management tank connected to an engine;
a third fuel flow channel to connect the management tank to the upstream side of the fuel pump and the flow meter;
a fourth fuel flow channel to connect the management tank to the downstream side of the fuel pump and the flow meter; 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
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 a 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.
