Ilmor Marine And Mercury Marine Release New Engines

While yesterday’s releases of Mercury Racing’s two new QC4v engines and one all-aluminum V-16 platform from Sixteen Power grabbed most of our attention, there were a couple of other noteworthy engine debuts from Ilmor Marine and Mercury Marine.

Based on the same 7.4-liter LS platform (454-cubic-inch) as Ilmor’s MV-570 engine, the new MV8 7.4L OPS recreational stern-drive engine makes 483 hp. It is paired with the company’s hydraulic One Drive and, according to a press release from the Plymouth, Mich., engine company, it “fills the power void currently experienced in the gasoline stern-drive segment between recreational duty 430 hp and high-performance 520 hp.”

The catalyzed, Environmental Protection Agency and California Air Resources Board emissions-compliant MV8 7.4L engine’s Ilmor-designed internal components include forged crank, rods and pistons. The engine comes standard with closed cooling and electric throttle, and features a performance tuned cast aluminum intake and easily accessible service points. It comes standard with a five-year/500-hour factory-backed limited warranty.

As for Mercury Marine, the Fond du Lac, Wis., marine engine and accessories company introduced a Mercury Diesel 6.7L mid-range engine family. The electronic common-rail engines will be offered in 480-, 500- and 550-hp versions and will be available as inboards or packaged with the Mercury Zeus pod-drive. The new engines is compatible with Mercury’s full suite of SmartCraft controls and electronics, including optional joystick piloting for inboards and joystick piloting for pods (Zeus).

“Mercury has established itself as providing the best integrated propulsion solutions to our customers,” said David Foulkes, (Mercury Marine parent company) Brunswick Corporation’s Vice President and Chief Technology Officer and Mercury Marine vice president of Product Development, Engineering and Racing,” in a press release from the company. “This is the first opportunity to provide our fully integrated ecosystem of technology and ease of boating features to our mid-range diesel customer.”
