An engine for an outboard motor includes an engine body and at least one piston, together defining a combustion chamber. An air intake system is arranged to introduce air to the combustion chamber. The intake system includes an intake conduit extending along the engine body. A fuel injection system also is arranged to spray fuel for combustion in the combustion chamber. The fuel injection system includes a vapor separator that contains the fuel and removes vapor from the fuel. The vapor separator is disposed between the engine body and the intake conduit. The vapor separator has a drainage mechanism to drain the fuel and an atmosphere introduction mechanism to introduce atmosphere that replaces a volume of the drained fuel. The atmosphere introduction mechanism has an operating member that has an axis along which the operating member moves. The axis preferably does not intersect with the intake conduit.
