Some marine propulsion systems use two propellers mounted at some distance from one another along the stern edge of a watercraft. Other dual prop systems take a different approach entirely, placing two propellers onto a single engine. This is the case with Volvo duo props. First introduced in the early 1980s, Volvo duo propellers were [...]
Volvo Duo Props Type T are engineered and designed for use with IPS drives. Unlike many other propeller systems that are fashioned out of stainless steel or aluminum, Volvo Penta Duo Props Type T are made from a carefully formulated mixture of three metallic substances: nickel, aluminum, and bronze. Nickel and aluminum are pure metals [...]
Volvo Duo Prop Type F has been designed for use with the DPS Drive. This drive can also be used with Type D duo props from Volvo Penta. The two duo prop systems are similar in several respects; for example, both can be used with gasoline engines and with diesel engines. However, there are some [...]
Many boat propeller systems have blades made out of either aluminum or stainless steel. There are also more options available that may be more appropriate for some propulsion systems. Volvo Duo Prop Type G is made of Nibral, a term which refers to an alloy of nickel, aluminum, and bronze. Bronze is an alloy in [...]
Volvo Duo Prop Type E have been specially designed and engineered to be able to work well with the DPX drive. This drive produces high speeds and makes substantial demands on any propeller system paired with it, but Volvo Duo Props Type E are up to the challenge. They can withstand speeds as high as 75 [...]
Volvo Penta Duo Props Type D are made of aluminum, a lightweight and corrosion-resistant metal that helps engines achieve high fuel efficiency due to decreased weight for the propellers. Volvo Duo Props Type D can be used with engines that run on either gasoline or diesel fuel and are specifically intended for use with the DP-S [...]
Volvo Penta Duo Props Type C work with drives numbered both DP280 and CP290. All Type C Penta duo props are fashioned from stainless steel, which as experienced boaters know, has several significant advantages. Stainless steel is resistant to corrosion, meaning that rust issues will be reduced. In addition, stainless steel is a strong metal [...]
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 [...]
Obtaining an ideal match of propeller and motor involves far more than simply making sure that you have the correct diameter and pitch figures. Propellers are far more complex than two specifications can capture, and they are one of the most vital components to any motorized watercraft. After all, the propeller largely determines whether the [...]
The popular image of a boat propeller is a shaft with one set of curved blades extending from it in a geometrically symmetrical pattern, but boating enthusiasts are also familiar with the duo prop. First introduced in 1982, Volvo duo propellers provide boaters with a more efficient propulsion system. This is because in Volvo propellers [...]
