About Twin Disc
Twin Disc is an American power-transmission manufacturer founded in 1918 and headquartered in Wisconsin, United States.
The company has a long history in mechanical and hydrodynamic power-transmission technology. Its marine business focuses on transmitting and controlling engine power through marine transmissions and related propulsion systems.
Twin Disc marine equipment has been installed in commercial vessels, workboats, patrol craft, fishing vessels, passenger craft and pleasure boats worldwide.
For accurate parts identification, the transmission model and serial information are normally more important than the vessel or engine model alone.
