Cummins MerCruiser Diesel is a Joint Venture between Cummins Inc. and Mercury Marine with a long-term vision to provide boat builders with a complete integrated system for vessel propulsion, power generation, controls and information for diesel engines. The combination of products, services, and expertise is unique in the diesel marine industry. Cummins MerCruiser Diesel provides a comparative advantage through the capability to guarantee performance and service as the industry's premier "prop to helm" performance source for boaters around the world, with diesel marine engines from 76-715 hp (57-533 kW) for commercial and recreational applications.
Recognizing the challenge of balancing the needs of the environment with the expectations of marine operators, Cummins developed the Quantum System MCRS engine family. This line of marine high horsepower engines not only is certified to the more stringent EPA Tier 2 emissions standards, but also delivers superior durability and reliability over other products in its class.
The QSK MCRS engine family features common technology components designed to endure the harsh marine environment, offer lower emissions and also meet Marine Classification Society requirements. The products build on the well-earned reputation of the KTA19, KTA38 and KTA50 marine engines as the proven leaders in high-hour, high-load applications.
Cummins also manufactures a complete line of marine filtration hardware, exhaust systems and control panels, all designed with the quality, technology and reliability you need to keep running strong. Plus, all are supported through the same distributor network to ensure complete system integration and global support.
