Abstract: In a personal watercraft and a buffer member of the present invention, a gunnel or the buffer member (bumper) functions as a sponson. An elongate-plate shaped sponson portion is protruded in a lower portion of a corner bumper provided on a side portion of a body along the longitudinal direction of the body. The sponson portion extends such that its longitudinal direction substantially corresponds with the longitudinal direction of the body. A rear end portion of the sponson portion has a width larger than that of a front end portion thereof. The corner bumper functions as the sponson as well as the conventional buffer member.

Abstract: A substantially U-shaped front bumper as seen in a plan view is mounted on a gunnel at a front end of the watercraft so as to partially cover the gunnel. The front bumper has a base portion attached to the gunnel, and an extending portion extending upwardly from the base portion so as to partially cover a streamlined surface of a deck. The base portion is provided with right and left concave portions extending in the lateral direction of the body. The extending portion is provided with a concave portion extending from one end to the other end in the lateral direction.

Abstract: A jet-propulsion watercraft, comprises a steering position sensor for detecting a steering operation of a steering operation means. A steering means adapted to be subjected to a steering assist mode control, when a signal indicating that the steering position sensor has detected the steering operation is received from the steering position sensor. A control device that gives a signal to the steering position sensor and receives a signal indicating that the steering operation means is or is not steered from the steering position sensor, and the signal from the steering position sensor is set equal in level to the signal given from the control device to the steering position sensor when the steering operation means is not steered.

Abstract: A holding structure for holding a device on a fuel tank can be manufactured by small man-hours, and is simple in construction and excellent in vibration isolating performance. The holding structure holds a device (11) inserted in a fuel tank (10) on the fuel tank (10). The holding structure includes a holding tube (19) formed integrally with the fuel tank (10) so as to surround an opening (18) formed in the fuel tank (10), an elastic boot (21) put on the holding tube (19) so as to be in close contact with the outer circumference (19a) of the holding tube (19) and the outer circumference (15a) of a part of the device (11), extending outside from the holding tube (19), and a fastening device (22, 23) for fastening the elastic boot (21) to the respective outer circumferences (19a, 15a) of the holding tube (19) and the device (11).

Abstract: Provided is an oil feeding structure of a personal watercraft capable of enhancing the appearance design of the personal watercraft and of readily letting air out of a tank during oil feeding, thereby smoothly feeding oil. A surface 15 inclined outward and downward is formed on both sides of the highest portion on a deck 2, that is, a portion between a housing portion B for a storage box 11 and a housing portion S for a steering mechanism. Oil feeding ports 9 and 10 are formed on the inclined surfaces, respectively. First and second oil feeding pipe members 17 and 18 are arranged downward in a substantially vertical direction from the oil feeding ports 9 and 10, and are connected to a fuel tank 7 and a lubricating oil tank 8 substantially rectilinearly, respectively.

Abstract: A lock device of a cover, especially of a hatch cover of a personal watercraft, having operation members disposed on a lower surface of the cover which is locked by an engagement with a hold pin and is released by a releasing operation of the operation members. The locking device includes a frame member having operation members located at both sides of and under the lower surface of the cover. The frame member further includes, a pair of slide members each of which slides in a direction away from the operation member by the releasing operation of each of the operation members, a moving member which is caused to move in the direction perpendicular to the sliding direction of the sliding members in response to the sliding movement of either one or both of the slide members, and an engaging member which moves together with the moving member to move into an engaging hole for engaging the hold pin.

Abstract: A steering structure of a personal watercraft comprising, a mount member 3 provided on a mount base 2 on an upper portion of a deck 1, a hold member 8 provided inside of the deck separated downward from the mount members 3 by a predetermined distance, a handle support shaft 4 supported by the hold member 8 and the mount member 3, and a support collar 11 provided at the handle support shaft 4, for rotatably supporting the handle support shaft 4, and for absorbing a deviation of support positions of the handle support shaft 4.

Abstract: A fin pad is disclosed for covering one or both of the fins provided on either side of the deck floor of a small water craft. The pad includes a cushion having an inner lower edge which curves toward and overlies portions of a floor mat covering the deck floor between the fins. A back sheet associated with the cushion is adapted to be fixed to the adjacent one of the fins and is anchored to the deck floor by an anchor associated with an inner edge of the back sheet and the deck floor.

Abstract: A jet-propulsion watercraft, comprises a steering position sensor for detecting a steering operation of a steering operation means. A steering means adapted to be subjected to a steering assist mode control, when a signal indicating that the steering position sensor has detected the steering operation is received from the steering position sensor. A control device that gives a signal to the steering position sensor and receives a signal indicating that the steering operation means is or is not steered from the steering position sensor, and the signal from the steering position sensor is set equal in level to the signal given from the control device to the steering position sensor when the steering operation means is not steered.
