ARNESON original spare parts

From the beginning of their production in 1980 to today ASD (Arneson Surface Drives) has become the most popular and used surface transmission system in the world, used for the construction of many recreational craft.

The rights to production and distribution of ASDs were acquired in 1992 by Twin Disc. Since then, the development of ASDs of different sizes has enabled a wide range of applications in the marine industry and today, the Twin Disc offers nine different model sizes for gas, diesel and turbine engines up to 10,000 Hp.
