Overview:

Engine Design – Robust engine designed for long life. Metric O-ring seals and edge molded gaskets eliminate fluid leaks. Aluminum pistons for exceptional durability

Fuel System – High Pressure Common Rail electronically-controlled fuel system provides constant high injection pressure regardless of engine speed or load condition. Benefits include low noise and vibration for quiet operation and faster load acceptance.

Lubrication System – Standard capacity (18 L [19 quart]) marine grade oil pan, plus a selection of engine mounted and remote lube filters for installation flexibility and ease of maintenance

Cooling System – Single loop, low temperature aftercooling eliminates the need for two keel coolers and lowers emissions. Tube and shell heat exchanger designed for superior durability and ease of service with minimal maintenance requirements.

Air Intake System – Rear engine-mounted water-cooled turbocharger from Cummins Turbo Technologies optimized for marine applications.

Exhaust System – Cast water cooled exhaust manifold for lower surface temperatures, safety and improved performance.

Electronics – 12v and 24v Quantum System electronics feature a proven ECM to monitor operating parameters such as fuel consumption, duty cycle, engine load and speed, while providing diagnostics, prognostics and complete engine protection. Simplified electrical customer interface box for all vessel connections to reduce installation complexity.

Certifications – Complies with U.S. EPA Tier 3 emissions regulations without the use of aftertreatment. Designed to meet the International Association of Classification Societies (IACS) and SOLAS requirements. Consult your local Cummins professional for a complete listing of available class approvals.

More Time on the Water. Less Downtime for Maintenance.

Lower Total Cost of Ownership. It’s a commonly held belief that boats are high maintenance, yet.
when your vessel is powered by a Cummins diesel, the truth is just the opposite. A recent analysis of routine maintenance practices on Cummins powered vessels, along with a meticulous review of the impact on performance, reliability and durability of our engines, has resulted in substantial increases in the recommended intervals for required maintenance on our marine diesel engines in both.
commercial and recreational use. That includes all Cummins QSB6.7, QSC8.3, QSL9 and QSM11 engines, regardless of model year. As you will see from the maintenance chart, virtually all of the
normal maintenance items are now extended out to a year or more if the hourly limit is not reached. Some procedures, such as the cooling system flush and vibration damper cleaning, need to be done only every four years or 2,000 hours. For most owners, that means that you simply do an annual checkup. The only exceptions to the list are the zinc anodes, which need to be
replaced every six months or 250 hours of operation. Having less downtime for engine maintenance means a lower total cost of ownership and an increase in the amount of time you can spend on the water.
