Cummins Marine Power Built for Serious Duty

Brisbane Marine sources Cummins marine engines and propulsion solutions for Australian vessels, from recreational yachts to demanding commercial, government and professional operations.

Proven Cummins Power Across the Marine Spectrum

Cummins brings one of the broadest marine diesel portfolios to the market, covering propulsion, auxiliary power, generator sets and integrated marine systems. Its range extends from compact and mid-range platforms such as the QSB, QSC, QSL and QSM families through substantially larger KTA, QSK and other high-output engines, with current marine offerings reaching several thousand horsepower. Cummins specifically develops marine power solutions for recreational boating, yachting, fishing, passenger vessels, tugboats, offshore operations, government and defence applications.

Brisbane Marine can source Cummins engines according to the actual requirements of your vessel and operation. That can include propulsion engines, auxiliary systems, marine generator sets, electronic controls and monitoring equipment. Cummins also offers its C Command electronics platform for engine monitoring and control, while its marine propulsion portfolio includes both mechanical K and N Series engines and electronically controlled Quantum Series systems.

From Yacht Propulsion to Heavy-Duty Commercial Power

Cummins is particularly suited to applications where reliability, sustained output and proven diesel engineering matter. Its published marine portfolio includes engines such as the QSB 6.7, QSL 9, QSM 11, KTA38 and QSK60, while larger platforms extend into substantially higher power requirements. Cummins currently lists the QSK60 at up to 3,000 hp and the QSK95 at 3,200–4,200 hp, demonstrating the breadth of the platform for demanding marine applications.

For Australian buyers, we can work from a new-build specification, existing engine identification, repower requirement or fleet procurement schedule. We can also investigate the associated controls, monitoring equipment, propulsion components and parts required to complete or maintain the installation. Cummins maintains global warranty, service and technical support resources, giving operators an established support structure behind the equipment.
