MERCURY RACING UNLEASHES NEW V10 400R HIGH-PERFORMANCE OUTBOARD

 A New Level of Wide Open Power and Technology for Luxury Sport Boaters FOND DU LAC, Wis. (February 14, 2022) 

Mercury Racing delivers more outboard performance punch with the introduction of the all-new Mercury Racing V10 400R model. Designed primarily to power performance boats to speeds well beyond 75 mph, the V10 400R offers more power and a higher RPM range than any outboard in this category. A host of exclusive Mercury Racing features further enhance the experience of piloting a Wide Open performance powerboat. “The Mercury Racing team has created a worthy successor to the legendary L6 400R outboard,” said Stuart Halley, Mercury Racing general manager. “The V10 400R offers more low-end torque, more peak horsepower, and better fuel economy than the L6. The new V10 400R delivers the potent performance and drivability that only Mercury Racing can offer.” The Mercury Racing 400R features a new naturally aspirated V10 5.7-liter [TR1]powerhead that is based on the proven design architecture of the V8 4.6-liter Mercury Racing 300R model. The 64-degree powerhead displaces the 5.7 liters while maintaining the compact width required for 26-inch center-to-center mounting on multi-engine transoms for seamless installations on new boats and repower applications. The Mercury Racing V10 400R will be available in four lengths – 20”, 25”, 30” and 35” – to accommodate any single or multi-engine performance application. Deep-Breathing QC4 The Mercury Racing Quad Cam Four Valve (QC4) design features double overhead camshafts and four-valve aluminum cylinder heads. A proprietary 92mm throttle body and tuned intake work with the QC4 head to maximize airflow and power. The exclusive heavy duty throttle body servo motor is designed to produce instant throttle response, while a Mercury Racing fuel pressure sensor provides precise fueling under acceleration to further enhance throttle response. A 6000-6600 WOT RPM range enhances peak horsepower and provides a broad window for propping any performance hull type. This deep-breathing engine utilizes Transient Spark Technology to digitally adjust spark timing to optimize low-end, hole-shot torque without sacrificing top-end horsepower. Advanced Range Optimization utilizes electronic sensors to precisely adjust the fuel mixture for the best-possible efficiency at all speeds. All of this thrillin
