CompuSki 3B Propellers

compuski-01

The standard by which other Ski Boat Propellers are judged !

If it’s speed you’re after…look no further than CompuSki. Basically, the blade shape section of this propeller is parabolic and raked aft rather than flat as is conventional.

This parabolic blade design reduces water “slipping off” the cupped blades and therefore creates greater efficiency from a more direct forward drive. This propeller is ideal for ski racing and high speed use, particularly with boats using a step up gear ratio.

Performance Advantages:

  • Improved top end performance
  • Acceleration throughout full RPM range
  • Ideal for step up gear box use
  • Larger blades – means higher thrust
  • Smoothness through geometric accuracy of manufacturing methods

Design Features:

  • Revolutionary parabolic design
  • Large blade area for more thrust
  • CAD/CAM computer developed
  • Varying pitch distribution
  • Patterns fully CNC machined
  • Unique Super Cup design
  • Individually pitchometer checked
  • Electronically balanced
  • Cast in Nibral as standard
  • Lustrous polished finish
