An outboard engine has an internal combustion engine as a prime mover, a throttle valve device including a valve element and a valve shaft supporting the valve element, and combined with the internal combustion engine, a driven unit combined with the throttle valve device, and a drive unit for driving the driven unit. The drive unit is capable of smoothly transmitting an external throttle-operating force to the driven unit regardless of its position. A throttle valve operating mechanism connects an operating lever included in the driven unit, and a throttle-operating Bowden cable included in the drive unit. The throttle valve operating mechanism is a linkage including plural links. Joints joining the adjacent joining parts of those links are ball-and-socket joints, respectively. The valve shaft has one end connected to the operating lever and the other end connected to a throttle position sensor. The valve shaft is inclined to a horizontal plane.
