700 SCI

The popular 700 SCi delivers unsurpassed power and performance. The combination of a powerful engine management computer with a 3.3 Liter Lysholm screw-type supercharger, roller camshaft, and sequential fuel injection results in impeccable idle quality, instant throttle response, and unmatched preformance throughout the 4800-5200 RPM-rated engine operating range. The 700 SCi’s use of idle speed control strategies, along with an exclusive dual shift switch and coupler design, result in ultra-smooth shifting for the dry-sump NXT6 drive. The optional Stage 1 X-haust Noise Reducer system brings the 700 SCi in compliance with most noise regulations outside of the European Union – a feature we’re not afraid to be loud about.

  • Supercharged

    The boost control bypass valve on the supercharger provides full power at increased ambient temperatures and elevations

     

  • Efficient

    The sequential fuel injection provides an improved idle quality and throttle response time, while using less fuel in the process

     

  • Corrosion Resistant

    Closed cooling and twin-walled stainless steel headers protect the engine from the corrosive salt water environment
