Abstract
An exhaust system for an outboard motor includes an improved construction that can be compact enough for the limited space afforded within a powerhead of an outboard motor. The outboard motor includes an engine and a support member arranged to support the engine. The engine includes a cylinder block that defines a plurality of cylinder bores. The cylinder bores extend generally horizontally and spaced apart vertically from each other to form a cylinder bank extending generally vertically. At least two exhaust manifolds extend generally vertically aside and along the cylinder bank. Pistons reciprocate within the cylinder bores. A cylinder head closes ends of the cylinder bores to define combustion chambers together with the cylinder bores and the pistons. The cylinder head further defines at least one exhaust port per each one of the combustion chambers. Exhaust passages communicate with the exhaust ports. The exhaust passages are coupled with the exhaust manifolds so that at least one of the exhaust passages is allotted to each one of the exhaust manifolds.
