7 New Must-See Marine Engines, by Capt. Richard Thiel (continued)
Mercury Marine unveiled four engines, including the Verado 350, now the most powerful engine in the Verado family of four- and six-cylinder supercharged four-stroke outboards. It runs on 89-octane gasoline, although Mercury says you’ll need 91 octane for “full performance.” Weighing 668 pounds, the 350 employs a new cold-air induction system to feed its water-cooled supercharger. If that’s not enough power for you, check out the Verado 400R from Mercury Racing. Even with its 7000-rpm redline, it too runs on 89--octane gasoline, although again, you’ll need 91 octane to get the most out of it. The 400R comes with Mercury’s Sport Master gearcase, which features low water pickups for efficient cooling at high speed, and is available in traditional black or cold fusion white.
If even the 400R doesn’t cut it either, try Mercury Racing’s 9.0-liter QC4v 1550 dual-calibration stern drive, “designed for race consumers looking for the thrill of a 1,550-horsepower race engine with the option of running as a recreational 1,350 [horsepower engine] on pump gas.” To get all 1,550 horses just push a button on the standard key fob, but make sure you’ve filled up with the requisite 112-octane racing fuel first.
Finally, Mercury announced a 200-horsepower version of the 250-horsepower 4.5-liter V-6 stern drive it introduced in May. Unlike most gasoline marine engines, it’s not a marinized automotive engine but was designed and built by Mercury for marine use. www.mercurymarine.com
