Ethanol-Powered Boat Wins the 2015 Lake of the Ozarks Shootout

American Ethanol claims top prize with 208 mph run.


A 50-foot Mystic catamaran powered by engines that burned e85 fuel ran 208 mph to claim the top prize at the 2015 Lake of the Ozarks Shootout. Surprisingly, the fastest V-bottom wasn't one of the best-known names on monohull performance. The 43-foot Black Thunder owned by Dennis Parvey took the top V-bottom honors at 145 mph.

Don Onken owns the 50-foot Mystic American Ethanol, which is powered by 7,700 hp worth of four supercharged V-8 engines, each of which makes about 1,950 hp. On each side of the boat's engine compartment, the two motors are linked with center couplers, and the combined powerplants put the power to the water via SCS gearboxes and No. 10 Arneson surface drives with Hering propellers.

“After a few hundred dyno pulls, we finally figured them out,” said boat owner Don Onken. For the 208 mph run, the boat was driven by Myrick Coil and throttled by Mystic Powerboats President John Cosker.

Coil took top honors in the Professional V-bottom category, driving and throttling an open-cockpit Outerlimits 52-foot V-bottom to 139 mph. In some of the more offbeat categories, Brad Rowland drove his South Bay pontoon boat to speeds exceeding 100 mph, and the Doris family at PlayCraft Pontoons put up some big numbers in their fleet of pontoon boats. Summer Richardson claimed the Queen of the Shootout by driving and throttling her DCB F29 powered by twin 1,050 hp Teague Custom Marine engines to an impressive speed of 147 mph. Debbie Bull drove while Randy Scism throttled Bob Bull's 52-foot MTI catamaran to 181 mph. All told, 229 passes were made in 64 classes. For complete results, check out
