For more than three-quarters of a century Twin Disc has been making boats perform better and more reliably. Their in-depth knowledge of a variety of marine craft - pleasure and commercial - and the various owner, operator and task requirements has lead them to offer successful, relevant products.

Marine Gears

Twin Disc marine products are designed, engineered and built to perform real tasks, really well, in the real world. Sometimes it’s glamorous work; sometimes it’s not so pretty. But it’s always necessary.

From luxurious pleasure craft to stealth military vessels to hard working tugs, work boats, fishing boats, pilot boats and wind farm supply vessels. Twin Disc products optimise the control of the engine’s horsepower, contributing to the boat’s overall performance, productivity, operating efficiency and cost-effectiveness.

Twin Disc marine products propel all kinds of vessels, on all kinds of water, all around the world.

FAST, SMOOTH SHIFT

No other marine transmission in the world shifts as fast and smooth as the Twin Disc QuickShift, yet it provides amazing control at near zero vessel speed.

INSTANT POWER TO THE PROPELLER

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.

SUPERIOR MANEUVERING CONTROL

It's difficult for a powerful diesel vessel to go very slowly with a conventional transmission. Reducing engine rpm to reduce vessel speed to an acceptable and manageable speed is not possible or could stall the engine. Not so with QuickShift. It regulates engine torque at extremely low speeds to slow the propeller speed down to 50 rpm or less — allowing you to manoeuvre at near zero boat speed, an incredible advantage in docking.

Power Take Offs 

There are two types of PTOs available via MIT; mechanical and hydraulic. 

Mechanical PTO’s are built for reliability and are ideal for a high percentage of basic actuation installations. 

Hydraulic PTOs are available in three different clutched models plus a fourth design without clutch. Within each model there are many style variations. They can be used wherever a disconnect is required between the driven equipment and the prime mover.

Electronic Controls

VERSATILE

Take precise control of your boat with the Twin Disc EC300 Power Commander® marine electronic propulsion control system. It’s designed to interface with all popular electronic engines and transmissions, including the revolutionary new Twin Disc QuickShift transmission.

SIMPLE

The fly-by-wire concept behind the EC300 makes the system remarkably easy to install on a new boat or retrofit on an older one. You’re running wires, not cable or hydraulic lines.

INTUITIVE

This highly sophisticated electronic platform is capable of learning your every move and operating to your particular style. With literally one finger on one lever, you can control propeller speed and direction, courtesy of the EC300’s single lever synchronization.

RELIABLE

Electronic control technology is used on the most sophisticated vehicles in the world, from airplanes to earthmovers. They couldn’t perform the way they do without it. The EC300 brings a higher level of performance reliability to your boat.

Don’t Buy Your Next Boat without Twin Disc EJS™

The Twin Disc EJS (Express Joystick System) absolutely revolutionizes docking and slow speed manoeuvring of diesel powered, conventional shaftline boats. With easy fingertip movements you control direction and speed — instantaneously and intuitively. No lugging. No lurching. No clunking. All thanks to proven QuickShift® transmission and EC300 control technology. The EJS smoothly and simultaneously actuates and controls engines, transmissions and thrusters. You can effortlessly move the boat in any direction and even pivot it on its own axis. Its performance dramatically exceeds any other propulsion system. EJS brings incomparable control and enjoyment to even the most difficult docking situations. Once you try it, you can’t imagine driving your next boat without it.

FEATURES

“Push, twist and go” directional manoeuvring proven QuickShift transmission and EC300 control technologies simultaneously and instantaneously controls engines, transmissions and thrusters during docking, eliminates steering wheel & control lever activities extremely intuitive responsiveness

Ergonomically friendly and remarkably easy to learn.
