Main Controllable Pitch Propeller
In the case of keeping the engine speed and rotation direction unchanged, CPP can realize the power output from ahead to zero pitch to astern by the continuous change of propeller pitch. No need to start the engine or change the speed frequently to combust the fuel fully，the fuel saving ratio is up to 50%.
Installation：Transom installation /Middle installation
Application：Ocean carrier, large tugboat,fishery administration boats, Ocean surveillance ship,navyship | Type | Hub φ[mm] | Propeller Dia.
