Q-propeller upgrade kit 79999 for SP75, SP95 & SP100 includes anodes.
The new five blade propellers is the result of over two years of development and thousands of hours testing.
They are designed to reduce noise, while still maintaining the efficiency of the Side-Power four blade propeller. Not only did we succeed in reducing the noise, but we also ended up with more thrust on most models.
- Noise reductions of up to 75% measured in controlled environments
- The expected and tested normal noise reduction in “average installations” 20-40%
- Quick and easy installation
- More thrust on most models
