Abstract: A set of parts for marine vessel propulsion assemblies is provided A propulsion unit includes a driveshaft, and a first connection module comprising one or more input shafts, wherein the propulsion unit and the first connection module may form at least a portion of a first propulsion assembly. A second connection module comprising one or more input shafts, wherein the propulsion unit and the second connection module may form at least a portion of a second propulsion assembly. The positions, in relation to the propulsion unit, of output shafts of the first and second connection modules, when the first and second connection modules are mounted to the propulsion unit, are the same.

Abstract: A propulsion assembly includes an assembly output shaft adapted to drive one or more power receiving devices, a first output driving shaft which is adapted to drive the assembly output shaft, and a second output driving shaft which is adapted to drive the assembly output shaft. The first output driving shaft extends in an angle to the assembly output shaft which is larger than zero degrees and smaller than 180 degrees. The propulsion assembly further includes a first input shaft adapted to drive the first output driving shaft and adapted to be driven by a first power supply unit, wherein the first input shaft extends in an angle to the first output driving shaft which is larger than zero degrees and smaller than 180 degrees, and a second input shaft adapted to drive the first output driving shaft and adapted to be driven by a second power supply unit. The second input shaft extends in an angle to the first output driving shaft which is larger than zero degrees and smaller than 180 degrees.
