2-Speed Reduction Gears The 2-speed reduction gear enables ordinary high-speed ocean travel when both low-speed power and high propulsion are required. Meeting these two conditions, Daihatsu offers a line-up of 2-speed reduction gears (2 speeds forward, 1 speed reverse) that provide highly efficient operation. A special handle for smooth clutch switching of these gears is also available for single-lever, 1 or 2-speed forward or reverse operation. Combined with an electronic clutch control system, this enables shockless clutch operation. These speed reducers are extremely popular for various ships, including merchant and fishing vessels.
