Caterpillar Marine Engines

Brisbane Marine sources Caterpillar marine propulsion and power systems for Australian operators demanding dependable performance, high power density and long-term operational capability.

Caterpillar Power for Demanding Marine Operations

Caterpillar’s marine portfolio covers an exceptionally broad range of propulsion requirements, from the C7.1 and C9.3 through C12, C18 and C32 platforms, extending into the larger 3512, 3516 and C280 families. Cat separates its marine solutions into commercial propulsion, high-performance propulsion, auxiliary engines, generator sets and control systems, allowing propulsion to be specified around the actual operating mission rather than a one-size-fits-all engine choice. Its C32, for example, is available across ratings from 660 to 1,600 bhp, while the 3512E reaches up to 2,550 bhp.

Brisbane Marine can source Caterpillar propulsion for recreational yachts, commercial vessels, fishing operations, offshore craft, workboats and other professional applications. We can work from an existing engine identification, new-build specification or repower requirement and investigate the appropriate engine, controls, instrumentation and supporting equipment. Caterpillar also maintains a global marine dealer and service network, providing an established support infrastructure behind its propulsion products.

Cat Engineering for Power, Reliability and Continuous Operation

Caterpillar marine engines are designed for applications where propulsion reliability and sustained performance are critical. The portfolio includes high-performance C32 configurations reaching 1,900 bhp, while the newer C32B provides 1,200–1,700 bhp with increased power density and emissions configurations including IMO II/III and U.S. EPA Tier 4. Larger Cat platforms extend substantially further for heavy-duty marine propulsion.

For Australian customers, our role goes beyond locating an engine. We can investigate the complete requirement, including propulsion configuration, controls, mounting considerations, auxiliary equipment, generator applications and replacement parts. Whether you require one Cat engine or a larger commercial procurement, our international sourcing capability gives you another route to securing the equipment your vessel requires.
