The drive comprises a main machine 11 for outputting power and a gear box 12 for connecting the main machine and the clutch.

One of the propellers of the marine propulsion device is connected with the clutch at the position below the waterline, and the rest propellers are arranged at the position of the ship body 1 above the waterline.

The clutch comprises a main clutch part 71 connected with the driver, auxiliary clutch parts 72 respectively connected with the propellers, and a clutch operating mechanism 73 connected with the main clutch part and driving the main clutch part to be connected with the auxiliary clutch parts. The main clutch part 71 and the auxiliary clutch part 72 are respectively provided with teeth which can be meshed with each other, and the main clutch part rotates along with the driver and drives the auxiliary clutch part to rotate through the teeth.

As shown in fig. 1-4, two propellers 2 and water jet propellers 3 are mounted on the hull, and the guide rails are correspondingly provided with a propeller guide rail 4 and a water jet guide rail 5 for moving the propellers. When one of the propellers is connected with the driver through the clutch, the power output by the driver can be transmitted to the propeller through the clutch and drives the propeller to work, so that the ship is driven to sail; when the ship meets special environment or needs to change the propulsion mode, the speed of the driver is reduced to idle speed or stopped; then the clutch control mechanism drives the main clutch part to be separated from the auxiliary clutch part on the current propeller; then, the conversion driving mechanism works to drive all the thrusters to respectively move along the corresponding guide rails until the original thruster (such as a water jet thruster) moves to a standby position, and an auxiliary clutch part on the other thruster (such as a propeller) is opposite to the main clutch part; then, the clutch control mechanism drives the main clutch piece to move again and is connected with the auxiliary clutch piece on the propeller; so far, the conversion of propeller is accomplished, and driver accessible clutch drives the screw work, continues to drive the boats and ships navigation.
