P1 SuperStock

Excitement By Design

P1 SuperStock is a one-design, single-engine offshore race series designed to be affordable, equitable and exciting for racers and fans. For competitors this racing is infectious. The course is constantly changing beneath you, which makes for spectacularly close and unpredictable racing – the hallmarks of the P1 SuperStock Championship. The races, which are either held over one or two days, include a significant prize purse and are all APBA sanctioned events. The race courses can be positioned close to shore, providing unparalleled spectator viewing. At the heart of the championship is the P1 Panther 28R race boat. Designed, built and tested in the USA, the boat has been engineered by the best race engineers in the industry, and tested in the harshest conditions possible.


Wide Open Offshore

The Mercury Racing 300R outboard is the exclusive power for the domestic and international P1 SuperStock Championship. Designed, developed and manufactured in-house, the naturally aspirated four-stroke 300R generates unprecedented torque and acceleration from the lower end of the power band up to maximum engine speed. The Heavy-Duty midsection features solid mounts and forged transom brackets with single-ram power trim and a remote trim pump designed to endure the harsh offshore environment. 

The side steering bracket provides a robust, integrated steering installation. The surface piercing Sport Master gearcase features low-water pick-ups and a crescent leading-edge for maximized efficiency and speed. All boats are equipped with hand-crafted Mercury Racing Revolution 4 XP propellers for precision matched race competition. The Mercury Racing 300R is designed to give race teams season-long reliability while operating on 87-octane (90 RON) pump fuel. 

Ready to Race

The 28-foot P1 Panther 28R race boat is a 3,550-pound, carbon-composite stepped mono hull with an enclosed cockpit. The Panther is equipped with Wilson Custom Composite racing seats, a Mercury Racing DTS switchable throttle system and Mercury VesselView display with integral chart plotter, a full breathing air system, powered hydraulic steering, and integrated VHF intercom system. The Mercury Racing 300R outboard can push the Panther to more than 80 mph on flat water.


As a presenting sponsor of the P1 SuperStock Championship, Mercury Racing supports this unique offshore racing series because it provides aspiring racers and crew an accessible opportunity to enter competition in a series with controlled costs and a focus on safety. Because all competitors are using the same equipment, the racing is close and exciting for racers and fans alike. What better way to experience the Wide Open lifestyle?
