Duoprop propellers - Aquamatic Propellers

Duoprop propellers for Aquamatic
When Volvo Penta introduced the patented Duoprop in 1982, it was the biggest event in boating since the propeller was invented. Twin counter rotating propellers bite hard to produce unparalleled thrust, straight and true tracking - even in reverse - plus faster acceleration on the plane.

Counter rotating twin propellers
The counter rotating twin propellers eliminates the lateral forces existing in conventional single prop sterndrives. That means the engine’s energy and power is concentrated on driving the boat forward - not sideways.

Matched with perfect balance
The key to success is the balance between the front and rear propeller. Through extensive propulsion engineering experience and testing the result is a perfect match between drivetrain and propellers.

Each propeller type is developed exclusively for a specific drive and engine. The front and rear propellers must interact in perfect harmony to deliver optimized performance. Volvo Penta has done extensive testing to ensure a perfect match throughout to complete drivetrain. Wrong balance leads to excessive wear on the drivetrain. That’s why it is vital to always choose Genuine Volvo Penta Duoprop propellers.

Faster acc eleration
Duoprop 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. At partial load you can expect between 10–12 % lower fuel consumption.

Faster planing
A better grip in the water means getting up onto the plane faster. And staying there at low revs.

Manoeuverability
Whether at high speed, making sharp turns, or when docking in a crowded marina – the grip is there. Duoprop also reduces the boat’s tendency to roll.

Lower vibration and noise level
Duoprop produces lower vibration and noise levels due to the fact that shock pulses are distributed over more blades. With its counter rotating propellers and unique blade geometry, they are almost cavitation free.
