In the era of consolidation on the maritime diesel engine market, it is refreshing to report news of a new competitor. Mack Trucks - well known and regarded for the quality, durability and life-cycle performance of its products in land based markets - has created a new business unit, MackPower, dedicated to manufacturing, marketing and servicing a lineup of mack diesel engines for a variety of uses, including marine applications. "There is a lot of potential in the marine (pleasure craft and commercial) market," said Carrie-Ann Baker, manager, sales and marketing. The unit's initial entrant is the Mack E7 mechanical design engine, and the popular Mack E7 E-Tech engine, which is a six-cylinder, 12-liter model featuring an electronic pump-in-line injection system.
