4 Blade CompuQuad

4 Blade CompuQuad

Product code

Product Description

The ideal propeller for your pleasure or commercial boat. After extensive research and development, using our sophisticated CAD/CAM equipment, this CompuQuadfour blade design has been developed to achieve a top end speed comparable to three blade styles while at the same time enhancing all of the traditional smoothness and efficiency characteristics of a four blade propeller.

CompuQuad propellers are produced from fully CNC machined patterns ensuring the geometric accuracy and quality of the finished product is exceptional. The larger blade area of this range reduces slip and cavitation, provides rapid acceleration, superior mid RPM range performance, exceptional all round efficiency and outstanding reverse thrust. However, the single most impressive feature of the CompuQuad is its smoothness of operation – this has to be experienced to be believed.

CompuQuad 4B 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 * Exceptional reverse thrust and smoothness
* Large blades for efficiency * Outstanding load carrying capability
* Varying pitch distribution * Lower RPM planing – true fuel efficiency
* Patterns fully CNC machined * Superior performance in adverse conditions
* Disc Area Ratio = 0.80 maximum * Rapid acceleration across full RPM range
* Better for restricted aperture * The ultimate in smooth operation
* Electronically balanced  
* Individually pitchometer checked  
* Cast in Nibral or Manganese Bronze  
* Super Cup design also (Nibral only)
