Product catalog summary

Introduction
Twin Disc introduces the QuickShift™ series of marine transmissions, designed to provide smooth, seamless shifts and instant power to the propeller, addressing the longstanding issues of slow, abrupt shifts and delayed actuation in marine transmissions.

Specifications and Features
The QuickShift™ transmission offers incredibly fast and smooth shifts, with a clutch response time of 0.05 seconds and full torque achieved in 0.2 seconds. This is significantly faster than standard marine transmissions, which take 0.75 seconds for clutch engagement and 2.0 seconds to reach full torque.

Technological Advancements
The system utilizes a GP-Valve combining advanced hydraulics with electronic technology, featuring two proportional solenoids and an electronic profile generator. This design ensures precise engagement without the need for adjustments, unlike competitive systems that rely on shims and springs.

Benefits of QuickShift™

Smoother Shifts: Provides more precise control, reduces stress on the driveline, and enhances passenger comfort.
Faster Shifts: Offers smooth, responsive thrust and improved maneuverability, especially in slow speed or idle zones.
Low Speed Control: Allows for effective docking and maneuvering, even at zero boat speeds, by regulating engine torque to slow propeller speed to approximately 100 rpms.

Practical Applications
The QuickShift™ system is particularly beneficial in crowded marinas and during docking, providing unparalleled control and reducing the risk of damage to expensive vessels. It is also equipped with a mechanical override for added reliability.

Conclusion
QuickShift™ offers superior technology and performance at a comparable or lower cost than other marine transmissions. It requires minimal setup and maintenance, making it a highly efficient and reliable choice for both pleasure craft and commercial marine applications.
