For the full written captain’s report, test and performance data, and more about the Mercury 4.6 L V8 Verado Series, go to:
Mercury has introduced an all-new 4.6-liter (279 cubic inch) V8 engine. It’s 35 lbs. (16 kg) lighter -- 600 lb. (272 ks.) rather than 635 lbs. (288 kgs.) -- than the previous-generation Mercury Verado 300, which was an inline-6 configuration.
The company says the naturally aspirated Verado will provide smooth, quiet power and optimize fuel economy. The powerhead is a large-displacement designed for more power and greater low- and mid-range torque, and for better acceleration.
The new Verados are available in 250- and 300-horsepower ratings.
