NOTHING ELSE COMES CLOSE

It took the vision and determination of acknowledged mechanical innovator and offshore racing enthusiast Howard Arneson to perfect the performance and reliability of surface-piercing propulsion. A WINNING HERITAGE Arneson personally piloted his unlimited boat to pleasure craft, commercial vessels as well as military numerous wins as well as the 1987 Offshore World applications. Today, Arneson Surface Drives are renown Championship. Along the way his surface-piercing as the fastest, most efficient, fuel-friendly propulsion propulsion system quickly became the dominating force in offshore...

SUPERIOR PHYSICS With conventional systems, a fully submerged propeller at high revolution disrupts or churns the water across the blades, thereby losing bite and sacrificing propulsion. The propeller of an Arneson Surface Drive expells the air/vacuum at the surface portion of the revolution, thereby leaving clean water for the propellers to bite into at the submerged portion of the revolution and enhancing propulsion. TRIMMABLE PROPELLER SHAFT With the ability to adjust propeller submergence while underway, you can align the engine power curve to the hull’s planing power curve. Converting...

RUNNING CIRCLES ARO PROVEN RELIABILITY Arneson Surface Drives are designed and manufactured for maximum duty applications and to last the life of your vessel. High quality corrosionresistant materials matched to exacting tolerances are used in all Arneson Surface Drive units. All models are available in manganese bronze for VECTOR THRUST STEERING Conventional propulsion systems deflect prop thrust off an external rudder, creating indirect, slower and less precise turning dynamics. An Arneson Surface Drive horizontally articulates the propeller shaft in the desired direction to provide...

EASY ACCESSIBILITY ROLLA PROPELLERS Propellers are more easily accessible because The Rolla name has been synonymous with the they’re not buried deep under the hull; yet they highest efficiency, highest quality propellers in the are still protected by the craft’s swim step or world since 1963. Rolla surface-piercing propellers cockpit overhang. This allows for convenient provide the optimum solution to any performance propeller installation, removal and inspections and application requirement. In combination with from a variety of locations, including the swim an Arneson Surface Drive...

ARNESON FITS ENDLESS POSSIBILITIES Arneson Surface Drives provide marine designers, boat builders and boat owners a new freedom of design innovation and flexibility. Compared to installations of competitive propulsion systems, Arneson systems allow greater flexibility of engine placement. This allows maximum utilization of space throughout the vessel and is well suited for modern aft engine-room yachts. WORRY-FREE CONVERSION Arneson Surface Drives can bring superior power, INSTALLATION FLEXIBILITY better overall performance and improved operating Arneson units are easily bolted to the...
