Twin Disc Marine Transmissions

Twin Disc

offers more than 100 different marine transmission models in a variety of configurations ranging from 35 to over 4000 horsepower.

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.

 

Our 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.
