A small planing watercraft includes: a body including a storage box and a lid, the storage box including an opening, the lid releasably closing the opening; an opening and closing sensor detecting opening and closing of the lid; and processing circuitry determining whether the lid is open based on a result of detection of the opening and closing sensor, and, when determining that the lid is open, outputting a signal indicating that the lid is open.

Small planing watercraft and processing method for small planing watercraft

A personal watercraft includes: a watercraft body including a hull and a deck covering an upper portion of the hull; a handle located above the deck; a straddle seat located rearward of the handle; and at least one speaker assembly located forward of the straddle seat and above the lowest point of an upper surface of the straddle seat.

Personal watercraft

A personal watercraft includes: a watercraft body made of a resin; a handle projecting upward from the watercraft body; a meter display device disposed above the watercraft body and forward of the handle; a meter cover made of a resin and covering a space from above, the space being adjacent to and forward of the meter display device and being in contact with an upper surface of the watercraft body and a forward surface of the meter display device; and an antenna disposed in the space.

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.

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.

Engine and personal watercraft

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.

Oil cooler and small watercraft

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 comprises a first water passage from a water jet pump to a cooling water passage of an engine . Water is forcibly sent by the water jet pump and led to the cooling water passage through the first water passage . The water flows through the cooling water passage while exchanging heat, and the resulting water is discharged outside the watercraft. The personal watercraft further comprises a second water passage opened in a surface of a body of the watercraft and communicating with the first water passage , and an opening/closing means for opening/closing the second water passage
