Abstract: A personal watercraft includes a rider operation member operated by a rider to be movable to an acceleration position for providing a forward movement command, a deceleration position for providing a rearward movement command, and a neutral position for providing an idling command, the neutral position being set to a position between the acceleration position and the deceleration position. The first operation section protrudes forward of an axis of the grip and the second operation section protrudes rearward of the axis of the grip. The first operation section and the second operation section are provided on an inner side of the grip, and the tip end of the second operation section is located inward of the tip end of the first operation section in a rightward and leftward direction. The upper end of an operation surface of the second operation section is located below the grip.

Abstract: An engine for a personal watercraft uses an open-looped cooling system and comprises a cylinder block having a water jacket within which cooling water flows, and a piston that reciprocates within the cylinder block, and a dimension of the water jacket in a reciprocation direction of the piston is equal to or less than a half of a reciprocation distance of the piston.

Abstract: An oil cooler of an engine for small watercraft. The oil cooler typically includes a mounting portion configured to mount the oil cooler on an outer wall face of an engine of the small watercraft, an oil passage configured to allow oil to flow therethrough and lead to outside of the oil cooler at the mounting portion, and a coolant passage through which coolant for cooling the oil flows, wherein the oil cooler is capable of being disassembled such that an inside of at least the coolant passage is exposed.

Abstract: Disclosed is a personal watercraft having a water cooling system of an engine, which allows inside of a cooling water passage of an engine or a water passage connected to the cooling water passage to be sufficiently cleaned and a clogged water-supply hole in an expansion chamber to be easily inspected or cleaned. The personal watercraft 1 comprises a first water passage 50 from a water jet pump 7 to a cooling water passage of an engine 4. Water is forcibly sent by the water jet pump 7 and led to the cooling water passage through the first water passage 50. The water flows through the cooling water passage while exchanging heat, and the resulting water is discharged outside the watercraft. The personal watercraft 1 further comprises a second water passage 53 opened in a surface of a body of the watercraft and communicating with the first water passage 50, and an opening/closing means 54 for opening/closing the second water passage 53.

Abstract: Disclosed is a personal watercraft capable of appropriately detecting temperatures of an engine and an exhaust manifold by using one temperature sensor and in particular capable of finding that cooling water flow is stagnant in cooling systems of them based on the detection of the temperatures. The personal watercraft comprises a water-cooled multi-cylinder engine placed in an engine room of a body, an exhaust manifold for gathering an exhaust gas from the engine, the exhaust manifold being cooled by cooling water, and a temperature sensor provided so as to be located downstream of the vicinity of an end of the exhaust manifold that is located downstream in an exhaust gas flow path.
