The new 5 blade special skew propellers are the result of over 2 years of development work and thousands of tests. They have been designed to reduce level of noise, while maintaining the exceptional efficiency of the old 4 blade Side-Power propellers. This goal was achieved, and Side-Power even chose to make them a little bit more aggressive on some models, increasing the thrust on some thrusters about 5%.
- Noise reductions of up to 75% measured in controlled environments
- The expected and tested normal noise reduction in 'average installations' 20-40%
- Will be delivered on all Side-Power models except the SP550
- Upgrade kits will become available for most 'SP' series thrusters with special adaptors
