Quicksilver, a brand of Mercury Marine, today introduced its all-new 409 MPI Bravo® FWC engine at the Land 'N' Sea Marine & RV Show in Las Vegas. For owners of older boats who are seeking to return to or extend their time on the water, the engine offers a thrilling boost in performance and is compatible with advanced digital technologies that provide even more reasons to breathe new life into a cherished classic with a repower.
The 409 MPI Bravo engine features increased durability and reliability in a package that is more compact, up to 150 pounds lighter and more fuel efficient than comparable big-block marine engines. The engine features a flat-plane crankshaft that generates serious torque and horsepower, delivering an exciting boost in speed and hole shot when repowering classic sterndrive and inboard boats.
"How often is a repower an instant head-turner?" said Quicksilver Engines Category Director Mike Horak. "Repowering with a 409 MPI Bravo engine is not just a repair, it's a fundamentally different and exciting experience. When the captain leans into the throttle, this engine will provide an amazing amount of authority and thrust. They'll be able to maneuver the boat effortlessly."
Rated at 400hp, the 409 MPI Bravo engine is designed to replace non-catalyst 6.1L, 7.4L, 8.1L or 8.2L sterndrive engines in 21- to 31-foot single-engine boats and 28- to 38-foot twin-engine boats built before 2010 (prior to 2008 in California).
Manufactured from all-new components, the 409 MPI Bravo engine features freshwater cooling, a durable Quicksilver cast-iron V8 engine block, aluminum cylinder heads and multi-point fuel injection for easy starting and smooth operation. Designed to operate on 87 octane fuel with up to 10 percent ethanol, it features ceramic-coated forged pistons, Black-X composite valves and other forged internal components to deliver reduced wear and extended engine life for years of trouble-free service on the water.
Compatible with Mercury® SmartCraft® digital gauges, displays and analog controls, the 409 MPI Bravo engine can be retrofitted into single- or twin-engine boats with standard or magnum transoms and MerCruiser® Bravo One X® or Bravo Three X® sterndrives. Typical required modifications include new engine mounts, adjustments to exhaust components and regearing the sterndrive unit to compensate for the 409 MPI engine's higher rpm range.
The 409 MPI Bravo engine is backed by the confidence of a Quicksilver three-year limited warranty. To learn about repowering your boat with a Quicksilver marine complete engine, ask an authorized Quicksilver repower dealer for more information.
