Here listed is a freshwater used 2003 Mercruiser 6.2 Mpi. This engine came out of a 2004 Searay boat that was parted out from Lake Travis Austin, Texas so it was only used in freshwater. The exact ECU hours is 149. This motor is like new and is in mint condition. Absolutely zero rust on this motor. It was equipped with a bravo 3, but will work for other bravos as well.
