    摘要: A personal watercraft is disclosed including a flotation portion, a strut extending from the flotation portion, and a motor pod is disposed along the strut with an electric motor operably coupled to a driveshaft. A hydrojet unit is removably attached to the motor pod and includes an inlet portion removably attached to the motor pod and a substantially cylindrical housing. The inlet portion includes a substantially conical motor interface with a shaft through-hole for receiving the driveshaft therein, one or more fins extending outwardly from the conical motor interface, and at least one ring encircling the conical motor interface and connecting to each of the one or more fins for inhibiting objects from passing through the inlet region. The housing defines a fluid flow path to an outlet portion. The hydrojet unit includes an impeller coupled to the driveshaft and a stator disposed within the housing.
