The new 4.3 MPI ECT (Emissions Control Technology) engine is the latest in Mercury MerCruiser’s comprehensive lineup of catalyzed engines ranging from 135 hp to 430 hp.Â
Scheduled to be released in January 2011 and rated at 220 hp, the 4.3 MPI ECT is designed to power everything from family runabouts to cruisers and houseboats.
The catalyzed engine provides clean power that meets EPA and California Air Resources Board emissions regulations – ensuring the engine can be registered without limitations.
“MerCruiser is committed to the gasoline market by providing a brand portfolio of engines that not only meet emissions requirements, but also deliver the best boating experience,” said MerCruiser Brand Director Facundo Onni. “The 4.3 MPI ECT completes that portfolio.”
The 4.3 MPI ECT – complete with new, fresh styling – joins six other catalyzed engines in the MerCruiser sterndrive lineup, including the 3.0 MPI ECT, 5.0 MPI ECT, 350 MAG ECT, 377 MAG ECT, 8.2 MAG ECT and 8.2 MAG H.O. ECT.
Like the popular non-catalyzed version, the 4.3 MPI ECT is built with a reliable V6 GM cast iron base engine, offers the exclusive Engine Guardian Protective system and is compatible with Alpha and Bravo drives.
The Mercury Marine engineering team has developed an engine that not only performs on-par with the non-catalyzed version, but also is quieter and more fuel efficient. In recent tests, the 4.3 MPI ECT proved to be 5 to 10 percent better in fuel efficiency at cruising speeds and 5 percent quieter in pass-by noise measurements.
Boat builders and service technicians will appreciate the simplified installation process and increased serviceability of this engine, which includes an easy-to-reach hot stud location, an easy-to-access oil cap, improved dipstick, color coded service points and easy maintenance features.
The 4.3 MPI ECT is available with MerCruiser’s exclusive SeaCore System with best-in-class corrosion protection and SmartCraft Integrated Marine Technology.Â
