PROBLEM TO BE SOLVED: To provide a device displaying a traveling distance or the like by a residual amount of a fuel by a GSP plotter in a boat with an engine. SOLUTION: An engine 2 is attached to the boat 1, and the boat 1 is constituted such that the fuel is fed from a fuel tank 3 to the engine 2. A fuel gauge 3a for outputting a signal of a residual amount of the fuel is attached to the fuel tank 3, and a fuel consumption signal from the engine 2 and the fuel residual amount signal from the fuel gauge 3a are input to a GPS plotter 4 attached to the boat 1. Further, an antenna 5 is connected to the GPS plotter 4, and a signal conversion circuit 6 for receiving the fuel consumption signal from the engine 2, a signal conversion circuit 7 for converting the fuel residual amount signal from the fuel gauge 3a of the fuel tank 3, a CPU 8 for calculating the traveling distance by the signals from the signal conversion circuits 6, 7, and a display device 9 are attached to the GPS plotter 4.
