An embodiment of a device for marine surface propulsion of a watercraft is provided that facilitates high speed performance in combination with steering and/or trimming control. The propulsion device may include a support member supportably interconnectable to and pivotable about one or both of a reclined axis and upright axis relative to a watercraft transom. A propeller shaft may be supported by the support member for pivotable movement therewith, and may have a first end interconnectable to a watercraft engine output. A hub body and a plurality of propeller blades may be interconnected to a second end of the propeller shaft for co-rotation therewith, wherein the hub body and propeller blades are pivotable with the support member about the reclined and/or upright axes. A variable pitch actuator may be interconnected to the support member for pivotable co-movement therewith about the reclined and/or upright axis, wherein the variable pitch actuator is provided for adjustably controlling a pitch orientation of the propeller blades.
