Abstract
This invention is an outboard motor exhaust device compatible with a small, lightweight cylinder block, which simplifies the exhaust manifold assembly and allows greater precision of assembly. The engine of an outboard motor is located above an engine holder, and comprises a horizontally assembled cylinder head, cylinder block, and crank case. An air intake device is located on one side of the cylinder block, and the exhaust manifold comprising the exhaust device is located on the opposite side of the cylinder block from the air intake device. A side surface of the cylinder head and a side surface of the engine holder are coplanar and form a support for the exhaust manifold.
