Ski Boat Propellers

CompuThrust

The Ultimate in Thrust and Smoothness for Ski Boats !

Put simply… this is the single most successful product our company has ever developed. We originally set out to design a propeller specifically for water skiing and the four bladed CompuThrust has exceeded our most optimistic expectations.

The CompuThrust has four parabolic style raked blades of totally unique CAD/CAM design. The total blade area is about 40% larger than normal three bladed ski boat propellers providing enormous thrust for both social and tournament water skiing. The propeller is exceptionally smooth and it simply won't "let go" throughout the full RPM range.

 

Performance Advantages: Design Features:
* Fantastic "hole shot" acceleration* Revolutionary parabolic design
* Excellent mid RPM range performance* Large blade area for more thrust
* Maintains higher speed on turns* CAD/CAM computer developed
* Massive blades for very high thrust* Varying pitch distribution
* Reduces overall fuel consumption* Patterns fully CNC machined
* Planing speed can be held at lower RPM* Unique Super Cup design
* Outstanding smoothness of operation* Individually pitchometer checked
* Electronically balanced
* Cast in Nibral as standard
* Lustrous polished finish
