Abstract
An exhaust system for an outboard motor powered by an internal combustion engine is disclosed. Preferably, the engine is of the 'V'-type, having first and second banks defined by first and second cylinder heads connected to a cylinder block. Each bank contains at least one combustion chamber, and the banks define a valley extending therebetween along a length of the engine. A main exhaust passage is defined through each cylinder head generally within the valley, and an exhaust passage extends from each combustion chamber of a bank to the main exhaust passage of that bank. The main exhaust passages of the two banks join into a single passage.
