Abstract

An outboard motor which can be mounted at the stem of a boat comprises a boat-side fuel tank (60) which is installed on the boat side, a fuel tank (29) on the outboard motor side which is installed near the front portion of an engine (21), a fuel pump (50) which supplies fuel to the engine, and a fuel changeover cock (37) which selectively switches the fuel tank on the boat side and the fuel tank on the outboard motor side to the fuel pump, and in which the fuel changeover cock (37) is installed below the fuel tank (29) on the outboard motor side. This results in short and compact piping of the fuel supply system. Moreover, the changeover valve can be switched so as to connect the fuel tanks thereby facilitating the filling of the tanks on the motor side.
