Repower engine

At Marine-Tec USA, 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 a Marine-Tec remanufactured engine… 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 3-angle cut for proper seating, and all of our heads are resurfaced and not milled. Before shipping out each Marine-Tec remanufactured engine, we pressure check, spin test and compression test the engine to ensure 100% quality and reliability.

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

 Most people are lead to believe that Rebuilt & Remanufactured products are the same thing, however, this is a misconception. An easy way to explain the difference is that a Rebuilt engine is like a used engine; built with used parts, while a Remanufactured engine is like new, and is built with all new or remanufactured components which were restored to the Original Equipment Specifications set forth by the manufacturer. 

 Remanufacturing is the process of disassembly and recovery at the module level and, eventually, at the component level. It requires the repair or replacement of worn out or obsolete components and modules. Parts subject to degradation affecting the performance or the expected life of the whole are replaced. Remanufacturing is a form of a product recovery process which differs from other recovery processes in its completeness: a remanufactured machine should match the same customer expectation as new machines.

A second onboard Propulsion Control Module (PCM) microprocessor enhances the versatility of the popular 1200 SCi –allowing owners to switch from the required 112 AKI race fuel at 1200 h.p. to the second PCM which enables the engine to run on 89 posted pump octane (R + M)/2, or (95 RON) Global rated fuel at 1025 h.p. Mercury Racing created the DualFuel 1200 SCi in response to the limited availability of fuels with the higher octane ratings at marinas and on-water facilities around the world.

The engine shares all of the mild mannered running qualities as its 850 SCi and 1075 SCi siblings. It is docile around docks but ferocious once unleashed. The 1200 SCi features a pair of Lysholm twin screw super chargers with multiport fuel injection (two injectors per cylinder). This combination provides sport boaters with turn-key starting, great overall running quality and incredibly smooth idle quality for a high horsepower big block.

Supercharger boost is variable. A boost bypass control valve, electronically activated by the PCM microprocessor, continuously adjusts the amount of boost needed to provide consistent horsepower. Under optimum ambient conditions, the boost bypass control valve will open to adjust for the lowest boost required to obtain the maximum rated horsepower.

Polished pulleys, clear anodized hose fittings, new graphics and our universal engine mount system packaged with the durable BAM Cyborg transmission and legendary dry-sump Six drive put the finishing touch on what is the ultimate in high performance sterndrive marine propulsion versatility.
