High performance Ski Boat style for step-up gearboxes
These propellers are designed for high performance vessels used mainly for ski racing and circuit racing. They are particularly suitable for propellers running at high RPM through a step up gear box. Blades are heavily skewed and raked aft to enhance performance.
Design Features:
- Large blade area for more thrust
- CAD/CAM computer developed
- Patterns fully CNC machined
- Individually pitchometer checked
- Electronically balanced
- Cast in Nibral as standard
- Lustrous polished finish
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
