QuickShift® Brochure - Twin Disc - #4

no MARINE TRANSMISSION in the world SHIFTS AS SMOOTH AND FAST, AND ALLOWS SUCH

LOW SPEED CONTROL.

Tom Ellswoth of Ellsworth Marine in California: "The QuickShift™ system will challenge every skipper's notion of how a game boat should perform. The QuickShift™ system obliterates the shackles of traditional conservative boat handling by putting unlimited control and power back into the hands of the captain."

the value of quickshift™ performance

Fast, smooth shifts combined with slow speed capability mean better vessel control and safer operation under all conditions. In addition, smooth, seamless shifts virtually eliminate damaging driveline shock that can be transferred to engine components. This should enhance the service life of your vessel's drive train components.

And, there's the enjoyment factor. Graceful, effi cient docking or departing is more comfortable on passengers and crew and ref lects operator competence. It's a pleasure to drive and ride a QuickShift™ equipped boat.

QuickShift™ offers far more technology and significantly better performance than any other marine transmission, at comparable or lower cost.

Unlike competitive systems, the Twin Disc QuickShift™ is a completely integrated transmission system, not merely an externally added-on valve. There's simply more technology, more performance, more reliability to the QuickShift™.

QuickShift™ requires virtually no setup for the boat builder or boat operator - no shims, springs, orifices. And if service is ever needed, it can be done outside the valve by adjusting main pressure or by replacing the controller. This dramatically reduces labor hours for service work.

HOW TO MAKE A FAST BOAT GO SLOW

It's difficult for a powerful diesel vessel to go very slowly with a conventional transmission. Reducing the engine rpms to get the vessel speed below five knots may stall the engine. But, with QuickShift™, Twin Disc has managed to regulate engine torque at extremely low speeds to slow propeller speed down to approximately 100 rpms. This means boat operators have controllable manoeuvring in the previously unattainable range of zero boat speeds - an incredible advantage in docking.

Even docking under calm conditions can be a challenge. In the time it takes to shift from forward to reverse with a conventional transmission, a boat traveling five knots can drift up to 13 feet! Continual manoeuvring compensation is needed to buffer the vessel's direction and momentum. QuickShift's immediate thrust and slow speed control "contains" the movement of the vessel more precisely and easily.

QuickShift™ is truly the only slow speed system that can be effectively used for docking and manoeuvring.
