In this episode, we’re talking with the team behind Freedom One Racing, a new name making waves at this year’s Lake of the Ozarks Shootout. The Shootout’s loose rules invite wild setups, and Freedom One didn’t disappoint, bringing a brand-new 388 Skater powered by twin 4,000-hp 4.9-inch bore, all-aluminum Noonan Hemi Pro Mod drag racing engines.  The boat’s engines are a marvel of engineering much of which is familiar to the 1/4 mile crowd, but unconventional to general marine performance guys. Topped by PSI screw blowers, the engines feature dry blocks (no water jackets) and require no cooling system. They employ MoTeC engine management systems and route the power to the surface drives through Coan Turbo 400-style three-speed transmissions.  The Freedom One boat was purpose-built for shootout style events like LOTO and came together just days before hitting the water. While some mechanical hiccups kept them from a full-speed pass, they still managed to hit 170 mph officially (202 mph unofficially). Not bad for their first outing!   We hear from team members Noah and Ryan Ola and Ryan Greco, as they discuss how this project came together, their big plans to break the LOTO top speed record, and why Freedom One is more than just a racing team—it’s a philanthropic effort with a mission to give back. Update: Since this episode was recorded, Freedom One Racing suffered a serious crash at the Desert Storm Shootout April 26, 2025 when the boat flipped at over 200 mph. This was the boat's first pass of the weekend and it's first run since the team's debut at the Lake of the Ozark's Shootout. While the boat was heavily damaged, the still unidentified driver and throttleman escaped with only minor injuries. As of now, we have not received an official update from the team regarding their future plans.

Slug Hefner’s Dirty Duck Racing team made history at the 2024 Lake of the Ozarks Shootout (LOTO), breaking the 200 mph barrier for the first time. After falling just short of the milestone in 2023, Hefner’s 438 Skater—powered by twin-turbocharged 557-cubic-inch engines—received a performance boost from a custom nitrous system designed by engine builder Carson Brummett. This upgrade propelled the boat to 202 mph, setting a new record as the fastest Skater and twin-engine boat in LOTO history. In this episode, Hefner shares the story behind his iconic Skater and the origins of the Dirty Duck name. He also reflects on his journey through the world of boat racing, from circle boats and drag boats to offshore racing. Hefner is more than just a record-setting racer—he’s a well-respected business leader and dedicated philanthropist. As the owner of Hefner Furniture & Appliance in Poplar Bluff, Missouri, Slug’s commitment to excellence extends beyond the water, shaping both his business and his community with the same passion he brings to powerboat racing.  This episode is brought to you by: SoCal Jet Boats the #1 online performance boating community forum, manufacturers of the coolest River Attire, hosts of the the Summer Tour with 6+ events along the Colorado River, and owners of The SoCal Jet Boat SpeedShop.

Billy Moore stands as one of the most successful offshore powerboat racers competing today. Following in the footsteps of his father, Bobby Moore—widely considered the first throttle man in offshore racing—Billy “works the sticks” in both Class 1 and Super Cat. I spoke with Moore recently, just as his Defalco Racing Class 1 team celebrated back-to-back wins at Mercury Racing’s Midwest Challenge in Sheboygan, Wisconsin. In addition to racing for Defalco, Moore throttles the C.J. Grant Racing/Graydel Skater in the Super Cat class. Not only did Moore gain invaluable racing insight from his legendary father, but he also learned the finer points of boat rigging and race boat setup, beginning his tenure at his father’s shop at 15. In this episode,Moore shares how the Defalco team made the strategic choice to switch from an Outer Limits hull to a Victory in the offseason and the challenges and rewards that followed. Based near Moore’s home in Washington, North Carolina, the Defalco team benefits from his close involvement. Moore is also a key figure at Checkmate Powerboats, which is owned by Pete Caldwell of Caldwell Marine Designs. He shares updates on Checkmate’s current direction and exciting future plans, including a possible trip out west to compete in the Parker Enduro.

Shane Westerfield is a versatile and accomplished racer with a rich history in both drag boat and car racing. Along with his father, Steve, he owns Westerfield Motorsports, a shop specializing in supercharged engines, components, and high-performance flat bottom boats. Westerfield’s 15-year drag racing career began by helping his father with his Top Alcohol flatbottom and reached a peak in 2017 when he won the NHRA Top Alcohol Funny Car World Championship. Westerfield has amassed 14 NHRA national event wins and continues to drive alcohol cars. He spent the last five seasons with Rick Jackson Motorsports and recently began driving Bucky Austin’s AA Nostalgia Funny Car where he won their first two events. Despite his success in car racing, Westerfield is most passionate about competing with his Blown Gas flat bottom in the National Jet Boat Association (NJBA) and Columbia Drag Boat Association (CDBA) and working to keep the class healthy and competitive as one of the few remaining "heads-up" drag boat racing classes. He has streamlined class rules and secured sponsors to increase prize money, ensuring its continued growth. In this episode, Westerfield shares the challenges of closing the family’s trade show exhibit company due to the COVID-19 pandemic. However, he explains how the setback led him and his father to pivot to their side project—working on boats and engines. They eventually transitioned to the business full-time, building a reputation for one-off custom work that has made them a go-to destination in the fast-boat community.

Ron Gordon, General Manager and Vice President, founded American Turbine with his boyhood friend, Bruce Simmons, in 1989, bringing decades of experience in the jet drive industry. Ron’s first encounter with a jet pump dates back to 1968, when he began working on his family’s Glastron V174 jet boat. Gordon’s career in the industry officially began in 1976 when he and Simmons founded Dominator Jet in Lubbock, Texas. After running the business for 12 years, they sold Dominator. Gordon stayed on as manager for a few years before he and Simmons left to start American Turbine. Gordon developed American Turbine jets from a “clean sheet of paper,” incorporating innovative designs and proven ideas from his years at Dominator. He was the original designer of key industry innovations such as the shouldered wear ring, Energizer kits, and larger impeller sizes ranging from AA to 9½ inches. American Turbine was also the first to offer high-performance intakes, high-flow bowls, and high-quality investment cast impellers. In 1993, Gordon sold American Turbine to Travis Garske, owner of Travis Pattern & Foundry (TP&F), ensuring top-quality production through TP&F's aluminum foundry and CNC machine shop. Gordon personally oversees the machining and hand-finishing of every impeller, emphasizing the importance of precision and craftsmanship that machines alone cannot replicate. Under Gordon’s leadership, American Turbine has continued to innovate, acquiring Dominator Jet in 1998 and Legend Jet in 2007. With over 48 years of experience, Gordon and his highly skilled team remain at the forefront of jet drive technology, delivering unmatched quality and expertise.
