The finite element method is used to calculate the strength of typical component and the whirling vibration of shaft system. The torsional vibration characteristics of the device is analyzed by the system matrix method，and combine the results of whirling vibration and torsional vibration， theoretical formula is used for the comprehensive verification of the whole system. Consequently The kinematic interference data of the double cross universal coupling，the stress magnitude and its distribution of the typical components，torsional vibration stress and other data are obtained. Furthermore， in-depth study is made for key technologies on the design and calculation of the surface drive propeller , the analysis process is summarized which can provide theoretical and engineering guidance for the design，calculation and analysis of surface drive propeller devices.
