This is the X-Act Performance .21 Sportive Marine 3-Port Nitro Engine with Pull Start. The XAct 21 MARINE Sportive Pull Start offers a great value engine package, using materials and components that offer an engine that punches far above its price point. The included pull start offers easy and reliable starting method, a great up grade for most RTR boats using a .21 and those looking to make a start on the race calendar.

The Sportive .21 uses a 3 port liner to offer high performance and used 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 standard head button requires a standard plug, for ease of tuning we recommend a hot plug is used.
