[origin: US5836795A] PCT No. PCT/EP95/04481 Sec. 371 Date Apr. 14, 1997 Sec. 102(e) Date Apr. 14, 1997 PCT Filed Nov. 14, 1995 PCT Pub. No. WO96/15028 PCT Pub. Date May 23, 1996A watercraft drive has a double rudder propeller driven by a driving engine via a driving shaft (1), an angular gear (3, 4) and an output transmission shaft (5). A propeller (6, 7) is arranged at each end of the output shaft. A guiding device made of guide blades (8a, 8b) is arranged between the propellers to correct aerodynamic conditions between both propellers (6, 7) and thus to reduce energy losses.
