ABSTRACT:
An arrangement of a speed sensor on a personal watercraft better shields the sensor from damage while simplifying the layout and arrangement of the sensor on the underside of the watercraft hull. The hull includes a pump chamber formed in part by a front wall. The speed sensor is attached to the wall with a portion of the sensor projecting below a housing of the sensor. A ride plate covers a lower opening of the pump chamber and fits about the sensor housing. In this location, the speed sensor does not interfere with the arrangement or operation of steering or trim mechanisms used with a jet propulsion unit housed within the pump chamber. The speed sensor also is generally protected in this location and is not visible from the rear of the watercraft to improve the watercraft's aesthetics.
