Work began with replacing mechanical throttle and shift Mercury Racing Bulldog sterndrives with our 8.6 Liter 540 sterndrives featuring modern Digital Throttle & Shift (DTS) technology.
Mercury Racing Digital Zero Effort Controls signal driver intent – providing digital throttle and shift signals to the potent 540hp engines. Power is transferred to Bravo One XR sterndrives spinning Mercury Racing Lab Finished Bravo I propellers. Integrated Transom Systems (ITS) featuring Integral steering rams provide a clean installation of the robust XR drives. K-Plane trim tabs assist in getting the classic vee -bottom up on plane as well as adjusting hull attitude while underway.
Vital engine and hull data is provided real-time via a touchscreen Mercury 703 VesselView monitor. It has more information and data on boat and engine functions than any other system in the boating industry: rpm, speed, fuel flow and efficiency, temperature, trim, and more.
Project 1080 also uses twin Garmin 7612 XSV chart plotters for engine data display as well as navigation. Stu walks us through the VesselView 703 features in the latest Project 1080 Update video.
Stay tuned for the next Project 1080 update where Stu will run us through the operation of K-Plane trim tabs and provide performance results from updating the Bravo One XR drives with surface piercing Sport Master gearcases.
We are excited to announce the reintroduction of the venerable 700 SCi sterndrive. The supercharged engine was first introduced in 2006 and was a popular offering for single- and twin-engine vee bottom, catamaran and deck boat applications throughout its initial 11-year run.
Although production ended at the end of 2017, demand for the 700hp engine has never waned.
Designed, developed and manufactured in house, the supercharged engine features a CNC-machined V8, 8.2L cylinder block packed with Mercury Racing designed and specified hardware.
The 700 SCi comes equipped with the Mercury-exclusive Propulsion Control Module (PCM) microprocessor. Combining the powerful engine management computer with a screw-type supercharger, roller camshaft, and sequential fuel injection results in impeccable idle quality, instant throttle response and unmatched performance throughout the 4800-5200 rpm engine operating range.
The PCM computer also enables individual cylinder control. The ability to optimize fuel, spark timing and knock control independently for each cylinder enhances engine running quality, performance, fuel economy and durability.
Supercharger boost is variable and automatically adjusted as needed. A boost bypass control valve, electronically activated by the PCM, continuously fine tunes the amount of boost needed to provide consistent horsepower. Under optimum ambient conditions, the boost bypass control valve will open to adjust for the lower boost required to obtain 700 crankshaft horsepower.
When operating in sub-optimal running conditions, the PCM closes the bypass control valve to provide active torque management throughout the engine operating rpm range and deliver the additional boost required to maintain a consistent 700hp.
The 700 SCi’s ability to provide consistent horsepower in any condition or locale eliminates the hassle of re-propping the boat to match conditions and enhances its versatility.
Power to the Water
The 700 SCi comes standard with the Mercury Racing-exclusive NXT1 transmission and legendary M6 surface drive. The innovative transmission design features a Bravo-like cone-clutch mechanism, resulting in smooth shifting characteristics.
