This is the X-Act Performance .21 Sportive Marine 3-Port Nitro Engine. The XAct 21 Marine Sportive offers a great value engine package, using materials and components that offer an engine that punches far above its price point.

The Sportive .21 uses a 3 port liner to offer high performance and uses a high quality 2 needle (+ idle) race carburetor for easy tuning and high performance. Using industry standard mounting points and OS Style threaded crank this is a drop in replacement in pretty much any .21 class boat. The turbo head button requires a turbo plug, for ease of tuning we recommend a hot plug is used.


  • 3 Port ABC Piston and Liner for high power output
  • Double bushed “PRO” Con Rod

Each engine is hand assembled in Europe and each component is inspected during this process to ensure high quality and long life.
