• Lightweight construction
• Additional components as option
• Mechanically or electrically controlled

From the smallest to the largest high-speed diesel-powered pleasure craft to a myriad of commercial boat applications, Twin Disc has marine transmission systems that precisely fit the horsepower and operating needs of each.

Standard marine transmissions feature helical gearing for quieter operation; hydraulic-operated and oil-cooled clutches for smooth, fast shifting; identical reduction ratios in forward and reverse, full power forward and reverse and minimal external plumbing.

Some models are available with down angle output to provide near-level engine installation, a feature of particular interest to boat builders for optimizing space within the vessel. For additional space savings, remote mounted V-drive and direct-mounted V-drive models are available.

• Short response time
• Smooth clutch engagement
• System control by proportional valve

The Twin Disc Quickshift® transmission system has forever raised boaters’ expectations of their crafts’ performance and their own.

No other transmission offers such shifting speed, smooth-ness, slow speed control, precision boat handling and safety.
Combined with the Twin Disc EC300 Electronic Controls, the Quickshift® system provides unparalleled boat control under all conditions.

One for all Twin Disc designed the Quickshift® system from the ground up to be a totally integrated system of transmission, valves, actuators and controls — all engineered to precisely fit and work together.

This engineering elegance and resulting performance and reliability cannot be duplicated by competitive products utilizing add-on components. It all comes from Twin Disc — one system, one manufacturer and single-source support.
