Abstract
An engine for a watercraft has an exhaust system having an exhaust pipe and an expansion chamber. The exhaust pipe has a plurality of runners corresponding to the number of cylinders in the engine. The runners extend upward to a merge point and then longitudinally in a generally forward direction. The exhaust pipe wraps around a front surface of the cylinder block and connects to an exhaust chamber. The exhaust pipe and exhaust chamber protect sensitive engine components, such as spark plugs and an exhaust control valve and actuating system from sloshing water. In addition, the exhaust system extends the length of the runners and enhances side-to-side balancing of the engine.
