This is what it says in the Mercury Propeller Catalog about this prop: Does your twin 135 - 225 HP outboard powered boat need more bow lift? Our 4 blade Vensura propellers might be what your boat needs. The Vensura is also an outstanding performer with your 18' - 22' sterndrive runabout or ski boat.
