The personal watercraft 1 shown in FIG. 6 has a sponson 61 at the rear of the hull 2 and on both sides in the width direction.
The sponson 61 is supported by the hull 2 so as to be vertically swingable by a support shaft 62 provided at a front end and an angle adjusting mechanism 63 connected to a rear end.

The angle adjusting mechanism 63 is connected to a switching mechanism 65 via a push-pull wire 64, and when the push-pull wire 64 is pulled by the switching mechanism 65, the sponson 61 can swing freely. A structure is adopted in which the sponge 61 is prevented from swinging by returning the screw 64. In this embodiment, the angle adjusting mechanism 63 employs a structure in which the position of the sponson 61 is sequentially switched to the following three positions each time the operation lever 33 is pulled up, that is, each time the push-pull wire 64 is pulled. ing. The three positions are Sponson 6
Reference numeral 1 denotes a horizontal position extending in the horizontal direction, a forward inclined position in which the sponson 61 is inclined forward and downward, and a backward inclined position in which the sponson 61 is inclined backward and downward. By changing the swing angle of the sponson 61 in this manner, the hull 4
Turning performance can be changed.

The switching mechanism 65 supports the operation lever 33 movably in the vertical direction, and is fixed to the deck 3. The operation lever 33 is disposed between the steering handle 8 and the seat 7 as in the case of the first embodiment.
It is urged downward by a compression coil spring (not shown), and a position where no operation is performed (lock position), that is, the upper end surface of the operation lever is located substantially on the same plane as the hull upper surface 38 (the upper surface of the cover 36). The structure adopts a structure in which it moves vertically between a position and an upwardly raised position (unlocked position), that is, a position where the upper portion of the operation lever 33 projects above the hull upper surface 38.

The switching mechanism 65 employs a structure in which the push-pull wire 64 is pulled by pulling the operation lever 33 upward, and the push-pull wire 64 is returned when the operation lever 33 is lowered.
In other words, the switching mechanism 65 includes the angle adjusting mechanism 63
Employs a structure in which the operation lever 33 switches between a lock state in which the swing of the sponson 61 is prevented and an unlock state in which the angle adjusting mechanism 63 changes the swing angle of the sponson 61. After the operation lever 33 is pulled up to change the position of the sponson, the operation lever 33 is returned to the locked position by the elastic force of the compression coil spring by releasing the finger pulling up the operation lever 33.

Therefore, in the personal watercraft 1 configured as described above, when the driver gets on and off the vehicle, or when the driver replaces the fellow passenger, the operation lever 33 for the sponson operation controls the operation of the driver and the fellow passenger. Since there is no obstruction, the driver and the passenger can move on the boat without being aware of the presence of the operation lever 33. In addition, since the operation lever 33 can be operated while the driver is seated on the seat 7, the operation of changing the swing angle of the sponson 61 can be easily performed.

The structure for changing the position of the reverse gate 51 according to the second embodiment and the structure for changing the swing angle of the sponson 61 according to the third embodiment are the same as those described in each embodiment. The present invention is not limited to this and can be changed as appropriate. For example, the operation system of the sponson 61 is made to swing freely by pulling up the operation lever 33 to the unlock position, and the operation lever 3
By returning the lock 3 to the lock position, the structure in which the sponson 61 swings can be prevented. In the case of adopting this structure, the swing angle is changed by grasping the sponson 61 with the operation lever 33 pulled up.
