Abstract
An outboard motor features a v-type internal combustion engine having a generally vertically extending crankshaft. Exhaust gases from combustion chambers are routed through a set of exhaust manifolds positioned within the valley defined by the two banks of cylinders. The exhaust flow is merged within a passage formed in the cylinder block prior to passing the exhaust flow into a passage formed within an exhaust guide plate to which the engine is mounted. The merged flow passage is positioned to allow a compact outboard motor construction. The motor also features a cooling pattern by which the exhaust manifold runners, the exhaust manifold, the cylinder head, the valley and the cylinders are cooled in that order.
