    摘要： A marine jet drive, for a boat having a transom and a drive shaft extending through the transom, the boat afloat in a water body, includes a support casing disposed aft of the transom and a pump shaft within the support casing, the pump shaft having an end connectable to the drive shaft. The jet drive includes a jet pump having a chamber and a blade coupled to a portion of the pump shaft extending into the chamber. The chamber is attached to and supported by the support casing aft of the support casing. The chamber has an inlet for receiving water into the chamber and an outlet. The blade is coupled to the portion of the pump shaft for co acting with the chamber to draw water into the chamber inlet and discharge water in a reactive jet out the chamber outlet to reactively propel the boat.
