1. 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; and
a controller configured or programmed to transfer fuel from one fuel tank of the plurality of fuel tanks to another fuel tank of the plurality of fuel tanks by the fuel pump; wherein
each of the plurality of fuel tanks includes a fuel sender; and
when transferring fuel from the one fuel tank to the another fuel tank by the fuel pump, the controller is configured or programmed to perform a calibration of the fuel sender of the another fuel tank by using a change in an output value of the fuel sender of the another fuel tank and a transfer amount of the fuel from the one fuel tank to the another fuel tank that is measured by the flow meter.
