A small-sized boat of the present invention includes a plurality of diaphragm type carburetors corresponding to each cylinder of a multicylinder engine. A crankshaft axis extends along a line extending through a bow and a stern of a hull. The carburetors include a plurality of shafts for throttle valves extending vertically in correspondence thereto, one throttle link connected to upper parts of the shafts for the throttle valves, and a plurality of diaphragm mechanisms having operating surfaces perpendicular to the crankshaft axis. By linking a plurality of the carburetors together to form an assembly of the carburetors, an overall size of carburetors is made small. Therefore, each carburetor can be mounted in a small engine room in correspondence to each cylinder of the engine.
