The present invention concerns an outboard propulsion device for a navigational seacraft comprising a propulsion means (4), at least one engine (1) supplying torque to a drive shaft (20) extending out of the engine and driving a transmission shaft (3) intended to supply torque to the propulsion means, the drive shaft and the propulsion shaft being in a fixed relative orientation, and a transmission means (2) connected at the input to the drive shaft (20) in order to receive the engine torque and transmit it at least partially to the transmission shaft. The transmission means (2) modifies the orientation of the engine torque and transmits it, in the form of modified torque, to the transmission shaft (3) to which it is connected at the output, and the transmission shaft (3) is a double universal joint shaft (30, 31) that extends in an inclined manner between the transmission means (2) and the propulsion means (4), the transmission shaft at least partially transmitting the modified torque to the propulsion means.
