FOND DU LAC, Wis. (June 20, 2018) – Mercury Racing is pleased to announce the Powerboat P1 SuperStock outboard racing series is repowering for the 2019 season with the all-new 4.6L V-8 four-stroke 300R outboard. P1 SuperStock, presented by Mercury Racing, is a one-design, single-engine race series. The new 300R will replace Racing’s 300XS as the exclusive power for the series for both domestic and international venues.
Designed, developed and manufactured in-house, the naturally aspirated four-stroke 300R shares Mercury Racing’s venerable Quad Cam Four Valve (QC4) sterndrive DNA. The stout V-8 powerhead provides an astounding 44% increase in displacement compared to the legacy two-stroke 300XS. That, combined with four valves per cylinder and the DOHC valve train, enables the new four-stroke to generate unprecedented torque and unmatched acceleration from the lower end of the power band up to maximum engine speed. All of this on 87-octane (90 RON) pump fuel while maintaining a comparable weight as its two-stroke predecessor. The weight savings can be attributed to state-of-the-art powerhead components, including composite intake runners.
Two midsection and three gearcase options are available for the 300R. P1 SuperStock will feature 300Rs with the Heavy-Duty midsection with a factory installed rear tie-bar mounting plate and side steering bracket assembly. The Heavy-Duty midsection features solid mounts and robust, 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, designed for boats capable of speeds in excess of 85 mph, features low-water pick-ups and a crescent leading-edge for maximized efficiency and speed. All boats are equipped with hand-crafted Mercury Racing Rev 4 XP propellers for precision matched race competition.
The 300R is backed by a three-year factory warranty with up to three years of Mercury Product Protection for a possible six years of warranty when used in recreational boating applications.
P1 SuperStock CEO Azam Rangoonwala said, “The P1 Panther race boat is at the heart of our SuperStock championship and strategic partnerships are an integral part of our business model, so the relationship with Mercury Racing is hugely valued. Embracing the latest technology by upgrading to the 300R outboard will not only increase racing performance but also maintain parity within the series.”
“We are very excited to continue our presenting sponsorship of the P1 SuperStock Championship. Their professionalism and focus is second to none,” said Mercury Racing general manager Stuart Halley.
“It is exciting to have our consumer products used in this highly competitive, one-design racing environment. There is no better way to prove their performance and durability,” said Steve Miller, director of marketing, sales and service for Mercury Racing.
The 2018 P1 SuperStock USA Championship season finale is June 30 - July 1 at the 34th Annual Sarasota Grand Prix Festival in Sarasota, Fla.
