Volvo Penta Twin counter rotating propellers bite hard to produce unparalleled thrust, straight and true tracking even in reverse, plus faster acceleration on the plane. Duo prop provides up to 30 % faster acceleration and produces a top speed some 5 % faster than any conventional single propeller system without increasing the fuel consumption.
- Perfectly matched pitch and camber distribution contributes to excellent propeller grip, optimal operational efficiency, safe and predictable handling.
- Optimized torque distribution between front and rear propellers ensures that the drive works with the load it is designed for – essential in preserving the life of the drivetrain.
- Precise balancing of each propeller gives minimal vibrations, quiet and smooth operation. It is also essential for efficiency and minimizes wear on the drivetrain.
- Shock-absorbing rubber bushings in the hub reduce vibration, turning and pulling forces and minimize stress on the drivetrain caused by gear-changes and propeller impact.
- Galvanic isolation – the propeller bushing is designed to galvanically isolate the propeller from the drive. It will greatly reduce anode consumption and prevent galvanic corrosion that could be caused by the propeller.
