Hitting a top speed of 208 mph, Don Onken’s 50′ Mystic Catamaran was a sure winner at the Lake of the Ozarks Shootout. To help power this boat across the finish line, Onken relied on twin V-16 Lightning Engines and Twin Disc Arneson Surface Drives.
«The victory is due to two years of hard work, the power of the engine and a drive able to take 4,000 hp,» said Onken. «Twin Disc has always helped us out. They’re the best there is at 4,000 hp. I’ve used Arneson drives since the mid-80s and I’m very satisfied with their performance.»
«They’re great, honest people to deal with,» continued Onken. «They’re very innovative and other companies just copy them.»
Twin Disc Arneson Surface Drives, including the ASD10 used by Onken, deliver the ultimate in speed, maneuverability, efficiency and dependability. Their surface-piercing propeller design reduces underwater drag by 50% compared to conventional systems. The prop blades and protective skeg are the only entities to contact the water, resulting in higher overall speed, quicker acceleration and a better payload-to-power ratio. There are significant improvements to fuel economy and lower operating costs as well.
The ASD10 features a bronze thrust assembly, internal lube oil reservoir, and steering and trim cylinders with external hoses and fittings. Requiring an overall length of 53″ from the transom, this model weighs 417 lbs. and has a maximum input torque of 2,000 ft-lbs. www.twindisc.com
