Coastal Wave Marine supplies Cummins QSM11 marine diesel engines for recreational and commercial vessels. The QSM11 range offers marine ratings from 300 to 715 hp, with selected high-output models listed by Coastal Wave Marine from 660 to 715 hp. The right engine depends on your vessel, required horsepower, operating speed, and duty cycle. Explore our Cummins marine engines to compare available models.
The Cummins QSM11 is a 10.8-liter, inline six-cylinder diesel engine designed for marine propulsion and auxiliary applications. Cummins offers different configurations and duty ratings, so buyers should compare the specific engine rating with the vessel’s intended use. See the Cummins QSM11 marine specifications for model details and published ratings.
When selecting a QSM11 for a new installation or repower, consider engine horsepower and RPM together with gearbox ratio, propeller requirements, vessel operating profile, and available installation space. For a replacement, identify your current engine model and serial number and check the mounting, cooling, exhaust, control, and electrical arrangements. You can also compare Cummins QSL9 marine engines and Cummins X15 marine engines when evaluating other power options.
To request a quote, provide your vessel make and model, intended application, required horsepower and rated RPM, current engine details if this is a repower, gearbox make and ratio, and delivery location. Photos of the engine data plate and installation can also help identify the right configuration. Contact Coastal Wave Marine for a Cummins QSM11 quote to discuss available models, configuration, warranty eligibility, and delivery.
