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.

The BCS outboard steering is the best answer to your needs of ‘CONTROL’ and ‘COMFORT’ at the same time. Built with no compromises of quality, BCS outboard steering can be adapted to the different mounting configurations to cover any outboard application.

Twin Disc offers a wide range of mechanical Power Take-Offs (PTOs) and Hydraulic Power Take-Offs (HPTOs).  Where operator access is complicated by machinery configuration, Twin Disc offers a new line of remotely actuated mechanical PTOs, offering safer, easier operation and greater equipment design flexibility. 

The BCS inboard steering is the best answer to your needs of ‘CONTROL’ and ‘COMFORT’ at the same time. Built with no compromises of quality, BCS inboard steering is suitable for single and multiple inboard engines with either single or dual steering stations.

The Twin Disc Express Joystick System (EJS®) absolutely revolutionizes docking and slow speed maneuvering of diesel powered, conventional driveline boats.

Twin Disc offers a new line of pump drives to meet a broad range of hydraulic system set-ups and application needs. These drives are available in a wide variety of gear ratios, including both speed increasing and reducing configurations.

When the boat is equipped with a bow-thruster it’s enough to push a button on the dashboard to move the bow or stern sideways and to perform nimble manoeuvres even in very narrow spaces.

It is crucial for the steering system to perfectly suit the vessel type and its main characteristics. BCS has developed a complete line of “Heavy Duty” steering components that are designed specifically for fishing or commercial boats and thus require much higher work loads and performance.

Twin Disc Power Commander Electronic Controls give you total propulsion control with electronic precision and literally fingertip ease. With only one lever required per engine, you can control your boat's speed and direction with one hand.

Twin Disc PO Air Clutches, available in sizes up to 1067 mm (42 in), are designed to give the user maximum dependability and lowest possible installation and operating costs.

Twin Disc torque converters minimize engine lugging and stalling and permit engines to operate within their most efficient speed range, producing rated horsepower regardless of load demand.

For the ultimate in speed, maneuverability, efficiency and dependability, nothing matches Twin Disc Arneson Surface Drives. Their surface-piercing propeller design reduces underwater drag by 50% compared to conventional submerged propeller drive systems.

The SeaProp60 saildrive is a propulsion system for sailboats with engines rated up to 56 kW (75 hp) @ 3600 rpm. Sailboat manufacturers and operators alike benefit from this system's unique but proven design.

With the addition of Rolla Propellers to Twin Disc's extensive line of propulsion equipment, engine manufacturers, boat designers, builders, owners and operators now have one source for the greatest combined propulsion technology.

The BCS trim tab systems are the result of over 40 years of experience and technological development: a continuous commitment in achieving higher performances, total control of stability in any condition, better maneuverability of the boat.
