Marine Gears

Twin Disc provide solutions for all varieties of craft 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 produce the Quickshift marine Transmission which is widely used with boat builders and has the following 3 key features:

•    Fast, smooth shift – it provides absolute control at near zero vessel speed.

•    Instant power to the propellers – Instantly delivering cushioned torque to the driveline when shifting from neutral to anywhere from full ahead to full reverse. It eliminates driveline shock while optimising power to the driveshaft. The QuickShift delivers a smooth power curve, whether full out or just nudge the throttle with its patented, completely internal and integrated clutch actuating system.

•    Superior Manoeuvring Control – QuickShift regulates engine torque at extremely low speeds to slow the propeller speed down to 50 rpm or less — allowing operators to manoeuvre at near zero boat speed, a great advantage in docking.

Industrial Transmissions

Twin Disc transmission systems for heavy-duty stationary and vehicular applications get the job done with precise propulsion control and optional power-splitting. Promote high productivity and low downtime with robust construction, advanced technologies and easy, reliable operation. Custom solutions solve your transmission challenges.

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.

Each model has many style variations. They can be used wherever a disconnect is required between the driven equipment and the prime mover.

Electronic Controls

Twin Disc EC300 Power Commander Marine Electronic Propulsion Control System.

•    Versatile – Designed to interface with all popular electronic engines and transmissions, including the revolutionary new TwinDisc QuickShift® transmission.
•    Simple – The fly-by-wire concept behind the EC300 makes the system easy to install on a new boat or retrofit on an older one. Wires are run instead of cables or hydraulic lines.
•    Intuitive – The highly sophisticated electronic platform is capable of learning the main operators every move and operating to their particular style. With one finger on one lever operators 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. The EC300 brings this higher level of performance reliability to all boats.

Twin Disc EJS™

The TwinDisc Express Joystick System (EJS) revolutionises docking and slow speed manoeuvring of diesel powered, conventional shaftline boats. With easy fingertip movements operators control direction and speed — instantaneously and intuitively. The EJS smoothly and simultaneously actuates and controls engines, transmissions and thrusters. Boats can be moved in any direction and even pivot it on its own axis exceeding other propulsion systems with its performance

EJS 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 and control lever activities
•    Intuitive responsiveness
•    Ergonomically friendly
•    Simple to learn and operate

Steering Systems

With more than half a century of engineering experience, Twin Disc steering systems deliver state of the art marine steering for all types of vessels. Systems that fit your application – outboard, stern-drive and inboard.

• Wide variety of applicaions
• Suitable for small leisure boats to large commercial vessels
• Electronic systems support more than 100 applications, functioning up to 230′
• Hydraulic cylinders and helm pumps suit applications from outboard steering to inboard steering

Trim Tabs

Performance, Safety and Efficiency

Control stability and enhance maneuverability in all conditions with Twin Disc boat trim tabs. Combine corrosion-resistant stainless steel systems or aluminum systems with four hydraulic kits and an array of accessories to meet your specific application.

Series MY3000, MY4000 and MY5000 are available in simple tab (single plate) type for smaller boats and lower loads, and the reinforced tab (reinforced plate) for bigger applications. MY3000 series tabs feature a welded connection cylinder.

Better performance

• Stern lifting and better balance
• Faster planing and more inline power
• Listing correction and reduced yawing and wandering

Increased safety

• Improved visibility
• Greater maneuverability at low speeds

Improved efficiency

• Better engine performance
• Reduced fuel consumption
• Stay on plane even at slower speeds
