357 MAG Bravo 4V

357 MAG Bravo 4V

325 Crankshaft Horsepower

Thanks to its size and power, this is the ideal replacement engine for 5.0L, 350 MAG, 7.4L and 454 engines that power cruisers, small sport boats and large runabouts.

383 MAG Bravo 4V

383 MAG Bravo 4V

350 Crankshaft Horsepower

Same power and more torque than a 454 HO carbureted engine. This torque monster delivers 429 ft-lbs of raw torque at 3800 RPM to launch even the heaviest boats with authority. When equipped with the same marine exhaust headers as found on the 383 Scorpion®, this engine produces 370 HP and 456 ft-lbs of torque—more than a 502 carbureted engine. This is the ideal replacement engine for 454HO and 502 HO carbureted engines that power cruisers, large runabouts, and sport boats. Marine exhaust headers sold separately.

383 MPI Bravo - Refrigerado por agua dulce

383 MPI Bravo - Freshwater Cooled

With 350hp and a full closed cooling system that supplies fresh water cooling to the engine and exhaust manifolds, this model is ready to repower 350 & 377 Bravo Horizon and SeaCore engines.
