Advantages of Volvo Penta Duo Props Type B
Volvo Penta Duo Props Type B are made of aluminum. Like all duo props, they feature two sets of rotating propeller blades rather than one set. Each set of propellers rotates in a different direction from the other: if one is rotating clockwise, for example, the other will rotate in a counter-clockwise direction. This design feature does not eliminate 100% of all cavitation, but it comes remarkably close so that in practical terms, concerns about cavitation can become a thing of the past.
Volvo Duo Props Type B work with DP280 and DP290 drives and were specifically designed so that the comfort of boat passengers could be increased even as very high revolutions of the propellers delivered the surges of raw power that are needed for top speeds and fast acceleration.
Each propeller on a Volvo Duo Props Type B has three blades, and each blade features an ultra-thin profile. Constructing these blades requires high-precision manufacturing, and Volvo stands behinds their products, backing them with a warranty so that customers can feel confident that if problems do occur, Volvo will be there to help. The warranty is also proof, however, of how unlikely it is for problems to arise. Volvo produces quality duo props and has no hesitation in offering warranties with generous and extensive terms.
Since many Type B duo props are produced by Volvo, be sure to consult a propeller guide that will help you choose the individual unit that is right for your watercraft and engine.
