Abstract
An outboard motor S has an exhaust manifold passage 37 for carrying exhaust gas from combustion chambers 30. The exhaust manifold passage 37 is formed in a part of a cylinder head 22 in an exhaust-side part of an internal combustion engine E on the side of the cylinder head 22 with respect to a joint surface P of a cylinder block 20 joined to the cylinder head 22. An exhaust passage 38 is formed in the cylinder block 20 and connected to the exhaust gas outlet 37e of the exhaust manifold passage 37 in the joint surface P. An electrical equipment box 50 holding electrical equipment is placed in the exhaust-side part so as to overlap the exhaust passage 38 when viewed in vertical direction. An electrical equipment box 50 is disposed adjacent to the cylinder head 22 with respect to the direction parallel to the axes of cylinders 20a. It is thus possible to increase freedom of arranging parts at positions farther from the cylinder head than the electrical equipment box and freedom of determining the sizes of those parts.
