Marine surface drive

In combination, a marine hull including an upstanding rear facing surface with at least a lower portion of said surface disposed below the at rest water line of said hull and including a power shaft journaled therethrough above the lower terminus of said surface, a support arm including front and rear ends, mounting means including pairs of first laterally spaced apart, rearwardly projecting and upstanding first mounting flanges rigidly mounted from and projecting rearwardly of said rear facing surface on opposite sides of said power shaft, said front end of said support arm including forwardly and downwardly inclined second mounting flanges disposed on opposite sides of said power shaft interdigitated with and pivotally supported from said pairs of first mounting flanges for up and down swinging of the rear end of said support arm relative to said hull about a first axis transverse to said hull between raised and lowered positions, respectively, said support arm including a depending strut rearward of said second mounting flanges, a propeller shaft journaled from said strut and at least generally aligned with said power shaft when said arm is in said lowered position, a propeller mounted on said propeller shaft, drive connection means drivingly coupling said power shaft to said propeller shaft, adjustment means operative to swing said arm between said raised and lowered positions, said rear end of said arm including depending rudder means disposed rearward of said strut and said propeller and mounted from said rear end for angular displacement about an upstanding axis, rudder control means operatively connected between said arm and rudder means for adjustably angularly displacing said rudder means relative to said hull, said first mounting flanges including rear portions spaced appreciably rearward of said first axis, stopper blocks extending between and interconnecting said rear portions of said pairs of first mounting flanges, said stopper blocks being engagable by said second mounting flanges to limit downward swinging of the rear end of said support arm to said lowered position, said drive connection means including a universal joint through which said first axis extends.
