A strut mounted, counter rotation marine propeller propulsion system of the single engine is provided including a depending propeller shaft strut (20) from which aligned front and rear propeller shafts (46, 44) are supported including remote ends disposed exteriorly of the strut and having front and rear propellers (50, 52), respectively, mounted thereon and adjacent ends drivingly interconnected through the utilization of bevel gearing (56, 58, 60) within a journal hub (36) carried by the lower end of the strut (20). The forward extremity of the front propeller shaft (46) is removably coupled to the rear end of a rearwardly and downwardly inclined power shaft (12) journaled through the bottom of the associated hull (10) and the strut includes horizontally outwardly projecting and forwardly and upwardly inclined opposite side water deflector plates (70) for smoothing out the water discharge, in conjunction with the strut itself, from the front propeller (50). Still further, the strut (20) is secured to the bottom of the associated hull through the utilization of structure (16) enabling its ready removable from the hull bottom without interfering with the water tight integrity of the bottom. |
