Quickshift® Transmission

No other marine transmission in the world shifts as fast and smooth as the new Twin Disc QuickShift®, yet it provides amazing slow speed control at five knots or less. With its patented, completely internal and integrated clutch actuating system, QuickShift® instantly delivers cushioned torque to the driveline when shifting from neutral to anywhere from full ahead to full reverse. It eliminates driveline shock while optimizing power to the driveshaft. And all this happens literally within milliseconds. So you have a steep but smooth power curve, whether you go full out or just nudge the throttle.

Smooth, seamless shifts and instant power to the propeller.

It's difficult for a powerful diesel vessel to go very slowly with a conventional transmission. Reducing engine rpms to get the vessel speed below five knots could stall the engine. Not so with QuickShift®. It regulates engine torque at extremely low speeds to slow propeller speed down to approximately 100 rpms — allowing you to maneuver at less than 5 knots and even accomplish zero boat speed, an incredible advantage in docking.
