MERCURY 1650 RACING STERNDRIVE

DESCRIPTION

Mercury 1650 Racing Sterndrive - The 1650 is based on the same four valve technology with quad cams and dry sump efficiency as its consumer siblings. Larger turbochargers, packed with an improved compressor wheel design, provide greater airflow for enhanced power and torque. The 9.0 liter quad cam four valve (QC4v) cylinder block and head design, combined with SmartCraft Digital Throttle & Shift (DTS), provides big power with luxury-car-like drivability. The DTS system also features one- touch Smart Start and automatic throttle synchronization, as well as shadow mode for triple or quad engine applications (where two throttle levers operate all engines). Zero Effort Digital controls provide an intuitive control experience - precisely signaling driver intent to the potent powerhouses.

The 1650 is close-cooled for more uniform temperature distribution, optimal running quality and longer life. Closed cooling, combined with a ball bearing supported compressor shaft, enhances 1650 turbocharger performance and durability as well.

Offshore racers will appreciate Mercury Racing's proprietary pulse-separated exhaust tuning which keeps turbos "spooled up," virtually eliminating throttle lag and low-end torque deficit.
