One tough marine engine.

Much tougher. And much better. They have to be after what the boater puts them through. It starts at the Mercury factory. It's the only place they remanufacture engines. Back where they were first designed and built. First thing they do is full dis-assembly. The head is completely taken apart and goes through a four-step, high-pressure "hot" cleaning process. Then they inspect everything. They machine, bore, and hone critical components to original tolerances. They replace cracked or corroded components (no weld repairs like you'll find with the aftermarket guys). We replace the oil pump, the valve springs, and all fasteners. They apply new paint. And finish up with a process nobody in the aftermarket can or will do. Hot testing. They fire up the engine and run it for at least 15 minutes under pressure. See if the oil and coolant are doing their job. See if the engine performs to the same high standards as a new Mercruiser engine. And to make it official, they back it the same way. With the same Mercruiser one-year limited factory warranty.

We are proud to offer these factory remanufactured engines.
