MerCruiser 8.1 MAG MPI 425 HP H.O.

The 425 hp 496 MAG H.O. is the most powerful MerCruiser engine available in our standard lineup. A special camshaft profile and unique fuel and spark calibration combine to provide an additional 50 hp and a 200 RPM higher operating range compared to the 496 MAG. Its massive power is coupled to a beefy Bravo X series drive with a number of performance drive options available for faster boats. Even with the additional horsepower, the 496 MAG H.O. is amazingly well-mannered and reliable. Standard low-restriction exhaust with stainless steel elbows, along with our most sophisticated spark and fuel injection systems, deliver outstanding acceleration and top speed.
