摘要： An exhaust system for a small boat is constructed in such a manner that an exhaust pipe extends rearwardly from an engine provided in a hull of the boat. A water muffler is provided in the exhaust pipe, and exhaust gas is discharged through a water lock pipe extending upward from a water muffler. A water lock pipe has an inverted U-shape. A resonator chamber for attenuating resonance of the water lock pipe is provided in the water muffler. The resulting configuration provides an effective system for reducing exhaust noise emanating from the small boat.

摘要： To provide an exhaust structure for a jet propulsion watercraft which can simply achieve a reduction of the exhaust noise. In the exhaust structure for a jet propulsion watercraft, a water jet propeller is provided in a pump room of a watercraft body. An engine for driving the watercraft is connected to the water jet propeller. An exhaust opening of an exhaust pipe is attached to the engine and is exposed to a pump room. A resonator for sound deadening is provided for the exhaust pipe. Further, in the exhaust structure for a jet propulsion watercraft, the resonator is bent in a meandering state such that bent portions thereof are positioned adjacent to each other so that the entire resonator has a substantially flat plate-like configuration. The resonator having a plate-like configuration is laid along a ceiling wall of the pump room.

摘要： A personal watercraft deck structure includes a deck, a rear portion opening provided continuously to the rear of a seat underlying opening in the deck, and a bridge member is removably attached at a boundary between the seat underlying opening and the rear portion opening (or at the rear portion opening). A rear portion of a seat is supported by the bridge member, while the rear portion opening is operatively closed with a rear cover. When maintenance of an engine and other equipment disposed within the deck structure is to be performed, the bridge member may be removed. As a result, the seat underlying opening and the rear portion opening are connected to each other and fully exposed, and therefore, a large opening can be obtained for facilitating maintenance of the engine and other equipment.

摘要： A rear grip structure for a small boat capable of discharging water which has entered the boat from between the hull side and the seat. The rear grip structure for a small boat has a structure in which an outer frame is formed into a hollow structure and is inclined upward. The outer frame 31 formed with the first eyelets at the lower portions on the left and the right and with the second eyelets at the portions higher than the first eyelets. This enables the outer frame to play the role of a drain trough, such that when water collects in the rear grip structure, it is taken into the hollow outer frame through the second eyelets. Thereafter, the water in the hollow frame flows down the incline of the hollow frame and is discharged through the first eyelets. The rear grip structure is mounted on the upper hull with a plurality of mounting bolts.

摘要： An exhaust pipe structure for a vehicle includes a vehicle body frame, a pair of occupant seats, and an exhaust pipe. The occupant seats include a driver's seat and a passenger seat and are disposed side by side in a vehicle width direction in a center frame portion. An internal combustion engine is disposed behind the occupant seats and supported substantially on a center line of the vehicle body in a rear frame portion. The exhaust pipe is connected to the internal combustion engine behind the occupant seats. The exhaust pipe extends outward in the vehicle width direction from the internal combustion engine, thereafter, is bent substantially in a U-shape to extend inward in the vehicle width direction, and then extends substantially onto the center line of the vehicle body. A muffler is connected to the exhaust pipe.

摘要： A small boat with a sponson for preventing splashing of spray onto the deck of the boat. The small boat is provided with a hull sponson at an outer periphery of the hull in order to fit the deck constituting an upper part of a boat body to the hull constituting a lower part of the boat body. A deck sponson is provided at an outer periphery of the deck, and the deck sponson is overlaid so as to bond with the hull sponson. The extent of projection of one member of the hull sponson and the deck sponson at the front section of the boat body is larger than the extent of projection of a member of the hull sponson and the deck sponson at a second member of the boat body. As a result, when the small boat is gliding and collides with a wave, the sponson prevents spray from the wave from splashing onto the deck.
