The invention relates to an integrated motor thruster vibration and noise reduction device which comprises noise reduction modules, vibration reduction modules and a mounting cylinder, the multiple noise reduction modules and the multiple vibration reduction modules are mounted on the two sides of the thruster correspondingly, and rubber springs in the vibration reduction modules are compressed to provide rated pressure for the thruster so as to reduce the vibration influence of the thruster; the noise reduction module is used for absorbing hydrodynamic noise generated in the operation process of the propeller, isolating external transmission of the hydrodynamic noise and reducing the radiation noise level of the propeller. According to the vibration and noise reduction device for the integrated motor propeller, the vibration and noise reduction requirements of the integrated motor propeller are met, and external transmission of vibration noise is effectively reduced through the vibration reduction module and the noise reduction module.
