To improve a freedom of layout within a narrow cowling of the outboard engine, achieve a reduction of manufacturing cost and an improvement of a maintenance performance of a filter member, a fuel supply apparatus in an outboard engine is structured such that fuel within a fuel tank is supplied into a vapor separator (V) via a low pressure fuel pump, the fuel stored within the vapor separator (V) is pressurized by a high pressure fuel pump (P) and is supplied to a fuel injection valve via a filter, a pump case (10) receiving the high pressure fuel pump (P) is arranged in a side portion of the vapor separator (10), an upper opening thereof is fixed by a cover member (14), a fuel discharge passage (15) connected to a pump discharge passage (PB) of the high pressure fuel pump (P) and a filter receiving recess portion (16) connected to the fuel discharge passage (15) are formed in the cover member (14), and a filter member (17) is detachably arranged in the filter receiving recess portion (16).
