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.
