CompuFlow

Propel yourself into the 21st century!

Using extensive research and development, CAD/CAM computer equipment and "on water" testing, Austral has developed the all new CompuFlow three bladed propeller range. This design incorporates a larger blade area than many of our competitor's products which has conclusively proven superior for improved efficiency and performance.

These larger blade area CompuFlow propellers provide efficient transmission of thrust from the engine to the propeller jet stream therefore minimizing the slippage commonly associated with average three blade propellers. The design is also suitable for commercial users who wish to optimize their boat's overall performance. CompuFlow propellers are made from fully CNC machined patterns ensuring geometric accuracy and therefore smoothness of operation.

CompuFlow 3B propellers are available from 14" - 52" diameter, in both right and left hand rotation and in an extensive range of pitch sizes.

Design Features: Performance Advantages:
* CAD/CAM computer developed* Optimum small sportcruiser performance
* Patterns fully CNC machined * Larger blades - means higher thrust transmission,
* Large blades for efficiency   less slip and cavitation
* Varying pitch distribution* Rapid acceleration across full RPM range
* Disc Area Ratio = 0.60 maximum * Smoothness through geometric accuracy of manufacturing methods.
* Electronically balanced 
* Individually pitchometer checked 
* Cast in Nibral or Manganese Bronze 
* Super Cup design also (Nibral only)
