A boat capable of assigning device instance numbers in accordance with the placement order of boat propulsion units, irrespective of the activation order of the boat propulsion units, comprises a plurality of control units for controlling a plurality of boat propulsion units. A plurality of gauge sections for displaying operation information of the respective boat propulsion units are connected to each other and to the plurality of control units via a communication network. The respective control units assign device instance numbers to the operation information of the boat propulsion units and transmit the device instance numbers, and the respective gauge sections identify and receive the device instance numbers for display. The control units are connected to each other via a communication line, and respectively include DI-number setting sections capable of setting device instance numbers, and determining sections capable of determining the positions of the boat propulsion units. The DI-number setting sections are adapted to set device instance numbers based on the number of the control units, and the positions of the boat propulsion units.
