Stock idle, starting and drive-ability quality is retained. Stock 5400 RPM limit is increased to 6000 RPM giving increased propping range and more power. Increased spark at low and mid speeds for increased overall performance. Increased low, mid and high speed torque for better acceleration with improved throttle response. Increased low-end torque for decreased planing time. Increased horsepower for improved top speed. 
Hi-performance PCM calibration with MPH gains of up to 9-10mph. This is accomplished through a more aggressive performance tuned PCM calibration as well as by increasing the supercharger output (increased boost) as well as a cooler set of spark plugs to increase combustion deficiency. The Stage 2 system provides even more power than stage 1 (approx 20HP more). Mercury Racing 600/662/and 700SCM Stage 2 Make this system functional and reliable. All of necessary components to required to. Stage 1 Performance computer recalibration. Maximum power output by more than 138HP* and 122 ft pounds of torque*. Upgrade features a performance computer recalibration that increases the The stock RPM limit of 5400 is modified to 6000rpm. By increasing the factory rpm limiter this gives customers the ability to greatly increase top speed MPH while running original props. Processing this added air will require cooling the engine just slightly as well as cooling the intake air charge through a bolt on water system upgrade to increase system pressure and intercooler efficiency, These power increase vastly improve onto plane times with a big gain in acceleration. Next a beautiful billet high flow flame arrestor is introduced to allow the supercharger to draw the added air into the engine. This is completed by down sizing the supercharger pulley to slightly increase air output. In order to take advantage of the performance calibration we need to let the engine breathe and process those gases efficiently. Mercury Racing 600/662/700SCM Stage 1 Kit MPH and power increase % are helpful rules of thumbs and are in no way guaranteed. 
We cannot guarantee speed or plane time increases with the many different applications. ***Results will vary depending on boat design, propping, atmospheric conditions, environment and drivers. NOTE: You will need to send us your ECU with this questionnaire for re-calibration. This kit also comes with an adjustable billet Flow Command fuel pressure regulator that allows you to tune your air fuel mixture for optimum performance. This kit include re-programming of your factory ECU in which we will modify both the fuel and spark curves as well as increasing your rev limiter and injector timing to 5400 RPM.
