The 51-foot Mystic Powerboats catamaran American Ethanol took a fifth straight Top Gun title on August 25 at the 31st annual Lake of the Ozarks Shootout in Sunrise Beach, Mo. Driver Tony Battiato and throttleman John Cosker posted a 201-mph run early on Sunday for the boat owner Don Onken. The Onken Racing team is sponsored by American Ethanol, Big Thunder Marine and Vortech Superchargers. An attempt by American Ethanol to exceed its 201-mph top speed posted in the morning ended in dramatic fashion on Sunday afternoon as the boat, which is powered by four engines, lost a propeller blade and the ensuing vibration caused a hatch to fly off of the boat. The team fell short of the 204-mph top speed the boat ran in 2017 and 2018.
