The Arneson 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 Arneson Surface drives come in various model sizes 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 Dual-Fin surface drives available in the ASD8 and ASD10 models.
