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.

Rolla Propellers offers a wide variety of services for virtually every aspect of propeller design, manufacture and application. Rolla stainless steel and NiBrAl surface piercing propellers range from 28 inches to 9.8 feet in diameter and include lines specifically designed for all major surface drive systems.

Since 1963 the name Rolla has been synonymous with the highest efficiency, highest quality propellers in the world. This means complete hydrodynamic engineering service, unique in the industry. Starting with a CFD analysis of the hull, including sea keeping, to the most sophisticated CFD propeller design methods for submerged and surface propellers.

This integration of hull analysis and propeller design allows the most efficient solution to any performance and use profile given. This is where no one else is today.
