      I found these specs online and I hope this is what you are looking for:

      Performance

      Force 50 hp marine outboard motors featured a wide open throttle minimum of 4,750 rpm and a maximum of 5,250 rpm. The engine utilized a gear ratio that measured 2-to-1.

      Propeller

      Force 50 hp outboard marine engines used three-blade, C-style propellers. At an optimal speed of 17 to 20 mph, the recommended propeller measured 12.25 inches in diameter with a pitch of nine degrees. For an optimal speed of 32 to 38 mph, the recommended propeller was 11.75 inches in diameter and 17 degrees in pitch.
