Mercury Racing has announced the Powerboat P1 SuperStock outboard racing series will repower for the 2019 season with the all-new 4.6L V8 four-stroke 300R outboard.
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 Quad Cam Four Valve (QC4) sterndrive lineage.
“The P1 Panther race boat is at the heart of our SuperStock championship and strategic partnerships are an integral part of our business model,” said P1 SuperStock CEO Azam Rangoonwala. “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,” added Mercury Racing general manager Stuart Halley.
The 2018 P1 SuperStock USA Championship season finale is June 30 to July 1 at the 34th Annual Sarasota Grand Prix Festival in Sarasota, Fla.
