Sterndrive HP1075 SCi - 1075 HP

Mercury Racing is pleased to announce the release of the HP1075 SCi sterndrive - the world’s most advanced big block performance sterndrive and latest innovation to come from the world leaders in advanced marine propulsion systems. The Mercury exclusive Propulsion Control Module (PCM) 03 microprocessor is the brain behind the brawn, giving this monster motor a friendly personality. Based on a high performance 557-cubic inch V-8 cylinder block, the 1075 SCi features a pair of Lysholm twin screw super chargers with multiport fuel injection (two injectors per cylinder). This combination provides sport boaters with turn-key starting, great overall running quality and incredibly smooth idle quality for a high horsepower big block. The engine’s 800 RPM idle speed makes shifting into and out of gear smooth as silk, making docking much easier with less chance of stalling and other low-RPM drawbacks normally associated with big horsepower. Mercury Racing, along with its parent company Mercury Marine, is the first marine engine manufacturer to be ISO 9001:2000 certified. The ISO certification is a reflection of Mercury Racing’s high standards and dedication to continue its leadership position in the marine industry. No other high performance marine engine manufacturer puts more time and attention to detail into product development. All products undergo numerous hours of grueling validation tests before they receive the Mercury Racing name. The 1075 SCi is the first engine to be accredited by Mercury Racing’s TEAM (Total Engine Application Management) initiative. The standardized TEAM process ensures proper installation of the engine with factory-specified components, providing maximum performance along with unmatched quality and durability. The 1075 SCi will only be sold to accredited OEM boat builders and dealers. Mercury Racing engineers designed the 1075 SCi for ease of installation. Every component is strategically placed with an end package that is as compact as possible. The twin screw compressors, which require less power than traditional roots blowers, sit on a corrosion resistant charge air cooler and induction system designed exclusively by Mercury Racing. Their low-profile design helps to reduce overall engine height and center of gravity. In fact, the 1075 SCi is eight inches shorter than the HP900 SC Dry-Sump, allowing boat builders to replace air scoops for sun pads. Super charger induction noise levels are controlled by twin carbon fiber Helmholtz air inlet resonators. Twin flame arrestors act also as air filters, keeping the engine’s air induction system clean and efficient. Super charger boost is variable. A boost bypass control valve, electronically activated by the PCM 03 microprocessor, continuously adjusts 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 1075 horsepower. The PCM 03 controller closes the bypass control valve, to provide the additional boost required to maintain a consistent 1075 horsepower when operating in sub-optimal running conditions and limited higher altitude environments. The 1075 SCi’s ability to provide a consistent horsepower in any condition or locale eliminates the hassle of re-propping the boat to match conditions. The PCM 03 computer also enables individual cylinder control. This ability to optimize fuel, spark timing and knock control independently for each cylinder enhances engine running quality, performance, fuel economy, and durability. The use of eight independent ignition coils, one per cylinder, helps eliminate spark plug fouling. The 1075 SCi comes equipped with the digital SmartCraft Controller Area Network (CAN) system, a network of sensors that proactively monitor engine functions. The next wave in boating, SmartCraft Integrated Marine Technology from Mercury links power, controls and internal and external sensors to provide precise data on all boat functions at a glance. The system monitors a variety of vital engine functions including fuel flow, fuel range, fuel used, and RPM, along with water depth, trim angle, water pressure and battery voltage. Boat functions monitored include fuel tank levels and water and waste tank levels. The CAN enables the PCM 03 to communicate data to optional SmartCraft SC5000 System View and System Link gauges for real-time data on multiple engine and boat functions. The PCM 03 also drives the exclusive Engine Guardian™ System. Engine Guardian monitors engine functions to forewarn of possible problems that could lead to engine damage. This “smart” technology not only detects and alerts the boater of a problem; it processes the data and reduces power to a maximum, safe level that allows the boater to continue operation. Engine Guardian also has the ability to proactively help prevent engine overheating by sensing not only engine temperature but cooling water pressure as well. By sensing water pressure, and temperature, the system can provide advanced warning to the PCM 03 control module, which then reduces engine power before temperature related engine damage takes place. Similar to the Mercury Racing Super Cat and Super V offshore race engines, the 1075 SCi features a dry-sump lubrication system. Three scavenge pumps and one pressure pump keep oil off the crankshaft, reducing friction for enhanced power and performance. A remote oil tank separates air from the oil and gives it time to settle, providing the pressure pump with a constant supply of oil. The oil tank also reduces foaming, improving overall oil lubrication, even in the most adverse sea conditions. Custom sealing systems, developed by Mercury Racing, enhance engine durability. The use of corrosion-resistant engine components and treatments enhance engine quality and protection against the corrosive saltwater environment. An all-new, thermostatically-controlled, high-velocity cooling system uses a combination of a circulating pump and sea pump to keep the engine at an optimal operating temperature and peak performance. The system utilizes a three-stage sea pump. Two stages feed cooling water to the engine block and cylinder heads while the third stage feeds the charger air cooler. Longer valve train life is the result of Mercury Racing dynamic optimization utilizing in-house valve train dynamics test rig. A high-output, 65-amp alternator provides increased power at idle and full power. The increased charging capacity makes running a variety of electronic accessories worry-free. The 1075 SCi is built from the bare block to completion in Mercury Racing's four-cycle Race Shop. Technicians use specialized components throughout the engine, from the heavy-duty valve train to the custom fabricated steel oil pan. Engine packages come standard with the Mercury Racing dry-sump Six drive.
