DWG 3D Propellers Files

[marcosateixeira]

Here at Federal Fluminense University (UFF - Brazil), we are looking for 3D .DWG files of 9 and 11 inches diameter propellers (all pitches - 2 to 1,5 HP outboard motors). This material is to be used to model building (using software).
Do someone know where to find such information?
Looking forward to hear from you:
