发明名称 Thrust enhancer for marine propeller
摘要 A thrust enhancer includes a peripheral ring with an exhaust ring concentrically supported within the peripheral ring by a plurality of radially extending circumferentially spaced struts. Each strut carries a blade that is preferably angled in the left-hand direction at about a 36 DEG angle with respect to a plane defined by the strut to redirect water flowing at lateral angles with respect to the axis of the propeller shaft so that the water moves more in alignment with the propeller shaft to cause the thrust forces caused by rotation of the propeller to be directed more completely aligned with the axis of the propeller shaft. Suitable brackets are provided for securely mounting the thrust enhancer onto an outboard motor housing or other mounting location aft of a marine propulsion propeller.
