The new Volvo Duo Prop propellers have been designed specifically to manage the massive torque and power of marine engines. The key to the incredible water grip is the combination of a 3-blade front and 4-blade rear propeller. The particular nickel-bronze-bronze (Nibral) alloy provides no growth and good corrosion resistance, and it is complete with full electric isolation.
Q4 Duoprop Set 21433624 innovative blade shape allows for the best possible interaction between the front and rear propellers, resulting in increased economy and a smoother, more comfortable ride. It's ideal for the DPH drive because it has shock-absorbing rubber bushing and galvanic isolation. The design, in combination with a material that resists stress and corrosion while also limiting expansion, ensures optimal performance and mobility.
