摘要： An exhaust system for a small-sized boat which can efficiently reduce exhaust noises in a low frequency band includes a water muffler provided at one location along exhaust pipes extending from an engine disposed in a boat body. The inside of the water muffler is divided into a single expansion chamber and a resonator chamber, and a front exhaust pipe coupled to the engine and a rear exhaust pipe opened to the outside of the boat are connected to the expansion chamber. Between the front exhaust pipe opened to the inside of the expansion chamber and the rear exhaust pipe, a water-controlling plate is provided in an upper side of the expansion chamber.

摘要： An exhaust apparatus for a small boat for reducing exhaust noise. A water muffler is provided at a midsection of the exhaust pipes extending from an engine which is provided in a boat body. An interior of the water muffler is partitioned into an expansion chamber and a resonator chamber with a front exhaust pipe connected to the engine and a rear exhaust pipe opening out of the boat being interlinked with the expansion chamber. The resonator chamber is directly connected to the midsection of the rear exhaust pipe via a connecting pipe. The water muffler is arranged in a longitudinal direction that is oriented in the fore-and-aft direction so as to extend along the side of a pump chamber in which a jet pump driven by the engine is arranged. A second resonator chamber is arranged along the water muffler on the outer side of the water muffler.

摘要： An air intake structure for a small watercraft for ensuring the capacity of an inter-cooler and for connecting the inter-cooler to a supercharger by a simply shaped communicating portion. In an air intake structure for a small watercraft, an intake passage and an exhaust passage can be disposed on the left side and the right side, respectively, of a plurality of cylinders. A turbocharger is disposed rearwardly of the engine with the turbocharger is connected to an intake passage via an inter-cooler. In addition, the inter-cooler is disposed rearwardly of the engine, with the distribution passage being disposed forwardly of and on the left side of the inter-cooler so as to extend in the forward and rearward direction. The inter-cooler is connected to the rear end of the distribution passage with an intake pipe contiguous to cylinders being bent rearwardly along a side surface of the engine body.

摘要： To provide an exhaust structure for a small watercraft that can cool exhaust gas, reduce the size and weight, and thereby cost of a backflow prevention chamber. An exhaust structure for a small watercraft is configured to be able to cool exhaust gas in the course of leading it to the outside when the exhaust gas of an engine is led to the outside for discharge. This exhaust structure includes a water muffler containing water therein. A backflow prevention chamber is disposed above the water muffler and adapted to prevent water from entering the side of the engine from the side of the water muffler. The backflow prevention chamber is provided with a cooling water injecting portion adapted to spray cooling water to the exhaust gas in an internal space. An outlet is formed in the bottom portion of the backflow prevention chamber to communicate with the water muffler.

摘要： An exhaust system for a small watercraft for effectively reducing exhaust noise and allowing a high output of an engine to be easily obtained at the time of high speed operation. An exhaust outlet of an exhaust pipe extending from an engine provided in a watercraft body is disposed at a position that allows it to sink in the water at the time when a travel speed of the watercraft body is a predetermined speed or less. The exhaust outlet is raised above the water at the time when the travel speed of the watercraft body exceeds the predetermined speed. An open surface of the exhaust outlet is offset toward a side wall surface of a pump chamber from a center of a jet pump in the pump chamber and is made oblique toward the side wall surface toward which the open surface of the exhaust outlet is offset.
