Mercury Racing Introduces All-New HP575SCi Sterndrive
Sets New Durability Standard for High Performance
Marine Propulsion
Fond du Lac, WI .----- Mercury Racing is pleased to introduce the all-new
HP575SCi sport boat propulsion package, the first Mercury Racing consumer engine
to feature both super charging and fuel injection. It is the highest output
powertrain package ever released by Mercury Racing to include a one-year limited
factory warranty.
A custom 256 CID Holley/Weiand Super Charger matched with a state-of-the-art
throttle body fuel injection system provides sport boaters with a robust torque
band throughout the 575SCi?s operating range. The 502 CID engine also delivers
turn-key starting, instant throttle response and improved idle stability for
easier docking. The 575SCi features the MEFI 3 engine control system.
The digital control system monitors a variety of vital engine
functions, including rpm, manifold pressure, air temperature, water temperature
and throttle position, keeping the engine in perfect tune. A thermostatically
controlled, high-capacity oil cooler brings engine oil temperatures up quicker
and keeps them more consistent. The oil filter is mounted on the front of the
engine for easy access, enhancing serviceability. From the engine accessory
pulleys to the new heavy-duty Bravo One XR Drive, the 575SCi sets an unmatched
durability standard for high performance marine propulsion.
Mercury Racing engineers scrutinized every component to ensure that the engine
would match the smooth operation and high reliability sport boaters have come to
expect from the ever-popular HP500 EFI. Technicians modify the GM performance
connecting rods to enhance strength and durability. Custom forged aluminum
pistons, designed by Mercury Racing, are matched with the handcrafted connecting
rods. Pistons and rods are then connected to a heavy-duty GM forged crankshaft.
High-quality specialty parts are used on the top end as well,
including high
performance push rods, rocker arms, valves and lifters. A custom billet aluminum
flame arrestor, set off with eye-catching graphics, sits atop the dual fuel
injected throttle bodies. Stainless steel tubular headers enhance engine
performance and aesthetic appeal. A one-piece serpentine belt system requires
less horsepower to drive the engine accessories including a 60-amp alternator,
power steering pump (idler pulley on models without power steering), circulating
pump and sea pump. The one-piece belt design is easier to service, requires less
maintenance and provides unsurpassed belt life. Heavy-duty billet aluminum
engine accessory pulleys are anodized in the classic Mercury Racing brilliant
blue.
The new Bravo One XR Drive features the race-proven Bravo One gear housing
packed with all-new heavy-duty components designed to endure up to 575 hp and
600 foot-pounds of torque. It?s brute strength comes from within:
