7.4L (454 ci) Remanufactured
Base Marine Engine




We carefully select only the most premium, low-hour engines to professionally remanufacture. These engines all undergo a 15-point inspection to insure quality, reliability and durability.

To give you an idea of all that goes into our remanufactured engines… the engine block and cylinder heads are completely disassembled, baked and blasted, checked again for cracks (magnafluxed), then reassembled using only the finest components. The engine block is always decked to insure proper sealing with the cylinder heads. The crank is either turned, polished or replaced, new Federal Mogul teflon-coated hypereutectic pistons (standard to .030 over) are installed, new or remanufactured rods, new Melling oil pump and timing set, new Hastings rings, new brass freeze plugs, new marine roller cam shaft and roller lifters (in applicable applications), new Durabond main bearings, cam bearings and rod bearings are used in all engines.

Cylinder heads are 2-angle cut for proper seating, and all of our heads are resurfaced and not milled. Before shipping out each remanufactured engine, we pressure check, spin test and compression test the engine to ensure 100% quality and reliability.

Most of our remanufactured engines come with the valve covers, marine oil pan, circulation pump and timing cover installed, unless otherwise specified.
