The invention discloses a pump jet propeller composite material guide pipe and stator connecting structure and a manufacturing method thereof. The pump jet propeller composite material guide pipe and stator connecting structure comprises a composite material guide pipe and a metal stator, the composite material guide pipe comprises a guide pipe surface layer and a metal framework, the metal stator comprises a stator ring, a plurality of stator blades arranged in the circumferential direction of the stator ring and a stator wing plate, and the stator wing plate is embedded in the guide pipe surface layer. The surfaces of the stator blades are provided with sunken areas, the composite fiber cloth of the guide pipe surface layer is laid in the sunken areas of the stator blades, then resin is poured to enable the stator blades and the guide pipe surface layer to be connected into a whole, and the guide pipe surface layer and the stator ring are each of a circumferential annular structure. According to the pump-jet propeller composite material guide pipe and stator connecting structure, the sunken area is arranged at the root of the stator blade, the size of a stator wing plate can be greatly reduced through the connecting scheme, the requirement for the construction space is small, and the pump-jet propeller scheme design is more flexible.
