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.

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.

Straight tracking

Duoprop tracks straight. Check over the transom of any Duoprop powered boat. The evidence of cleaner, unruffled delivery of power is there in the wake.

Faster acceleration

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 and 12 % lower fuel consumption.

Faster planing

Better grip in the water means getting up and onto the plane faster. And staying there at lower revs.

Handling is better too

Whether at speed, round the buoys or when docking in a crowed marina. The grip is there - even when making sharp turns at high speeds. Duoprop also reduces the boats tendency to roll.

Lower vibration and noise levels

Duoprop produces lower vibration and noise levels due to the fact that the shock pulses are distributed over more blades. With its counter rotating propellers it's almost cavitation free.
