(Charleston, South Carolina) – Cummins MerCruiser Diesel answers the yachtsman’s call for increased power and speed, with the introduction of a new line of QSM11 engines that contribute to better environmental sociability, and that maintain the reliability for which CMD is known. The QSM11-715 rating, (705 bhp) is EPA Tier 2 certified in the recreational market.

Engineers achieved the higher rating by refining performance components, including an ingenious new piston bowl design. The addition of a deeper bowl and finely tuned injector spray angle resulted in reduced soot levels. Next, a new camshaft was adopted to permit increased injector flow rate without overloading the camshaft. Additional testing resulted in the development of a new generation of injectors to match these two new components.

To ensure durability, CMD beefed up the flywheel and oil pan to accommodate the higher engine speeds. Now rated at 2500 rpm, up from 2300 rpm in the lower hp offerings, the QSM11-715 has improved performance on the propeller curve yielding better slow speed maneuvering around the dock. Boaters will also notice stronger acceleration and better overall top end vessel performance. With a cruise engine speed of 2300 rpm, the QSM11-715 has more available horsepower and torque than its QSM11-670 sibling running at the same engine speed.

As with earlier QSM11 engines, the in-line 6-cylinder, 4-stroke diesel is designed for quiet and fuel-efficient operation. A low profile design allows for ease of installation and easy service access. Replaceable wet cylinder liners result in longer life and lower rebuild costs.


Based in Charleston, South Carolina (USA), Cummins MerCruiser Diesel is responsible for designing, manufacturing and providing reliable after-sales support worldwide for marine products. It offers a broad range of power, with available ratings from 120-715HP for recreational applications and 77-588HP for commercial use. Cummins MerCruiser Diesel is a joint venture between Cummins Marine and Mercury Marine and can be found on the Internet at www.cmdmarine.com.
