Mercury Racing unleashes the next generation of high-performance outboards: the 300R and 300 ROS.

Join us at the legendary Lake X as motorsports icon Travis Pastrana puts both engines through their paces. From the competition-ready 300 ROS to the luxury-performance 300R with 15-inch HD CMS, these V8 powerhouses are built to dominate.

Featuring Mercury Marine’s 4.6L V8 platform, both engines deliver unmatched acceleration, durability and customization for racers and performance enthusiasts alike.

Two engines. One legacy. Pastrana approved.
