Abstract
An engine for a small watercraft, having an exhaust system that extends from an engine body and then generally surrounds the engine body. An air chamber of an air induction system for the engine, which has a relatively large volume, is located under the exhaust system. An exhaust manifold of the exhaust system has a slant opening, from which the other components of the exhaust system extends. A single, rigid coolant delivery conduit is affixed to the exhaust manifold so that a coolant jacket therein can be supplied with coolant through the delivery conduit. A plurality of carburetors each having a throttle valve are provided for the engine. A control mechanism for controlling an opening of the throttle valves is positioned at one side of the carburetors, while an interlocking mechanism for activating the throttle valves synthetically is positioned at another side of the carburetors.
