The invention discloses a suspension type marine Z-shaped counter-rotating propeller propulsion device which comprises an upper gearbox, a lower gearbox and a drive shaft. A power input shaft is connected to the upper gearbox, a propulsion counter-rotating propeller component is connected to the lower gearbox, one end of the drive shaft is connected to the lower gearbox, the other end of the drive shaft is connected to the upper gearbox and connected with the power input shaft, and the power input shaft transfers power to two propeller shafts of the propulsion counter-rotating propeller component by penetrating through the upper gearbox, drive shaft and the lower gearbox in sequence. Accordingly, by means of the suspension type marine Z-shaped counter-rotating propeller propulsion device, the drive structure can be simplified, intermediate drive steps are reduced, and the safety and the reliability are improved; by means of a counter-rotating propeller, inconsistent thrust during positive and reverse rotation is avoided, the rotating wake energy is absorbed, and the propulsion efficiency is improved.
