Magnum Marine

Twin Disc Southeast maintains a very active involvement in the Arneson^Ž Surface Drive product line. The exclusive supplier to the famous custom performance yacht builder Magnum Marine, Twin Disc Southeast has worked closely with this manufacturer and others in this highly technical mission-critical environment.

The Arneson^Ž Surface Drives are among the most efficient marine propulsion systems in the world. Their surface-piercing propeller design reduces underwater drag by 50% compared to conventional submerged propeller drive systems. The only surfaces to contact the water are propeller blades and a protective skeg. This results in higher overall speed, quicker acceleration, and a better payload to power ratio... AND... 50% less drag significantly improves fuel economy while lowering operating costs.

For work, pleasure, gas, diesel, or turbine power systems capable of torque outputs exceeding 30,000 ft. pounds, the Twin Disc Arneson^Ž Surface Drives come in seven models and various configurations for each model. Available in, Aluminum or bronze castings, straight or drop-center models, 12 or 24 volt compatible systems, plus the new Arneson^Ž Dual-Fin surface drives available in the ASD8 and ASD10 models.

ADVANTAGES

15% to 30% speed increase over conventional systems.
15% to 30% increase in fuel efficiency.
Low maintenance requirements.
Ability to adjust propeller submergence while underway.
Ability to adjust submergence to match horsepower output permits conversion of more thrust as appropriately needed.
Propellers ventilate to the surface rather than cavitate under the hull reducing noise and destructive hull and prop erosion.
Shallow water operation (elimination of underwater appendages).
Accessible propeller servicing.
Steerage by the positive thrust of the propeller and not by the propeller thrust to the rudder. This is equivalent to sports car rack-and-pinion steering performance.
For all it's sophisticated performance, it is a less mechanically complex and fragile design than other propulsion systems.
All models are available in manganese bronze or aluminum.
No limitations to shaft angle, blade top clearance, draft to restrict selection of optimum diameter propeller.
Adaptable to a wide range of engine applications, whether gas, diesel, or turbine.
