If the ocean is the ultimate yearning for freedom, surging power is the cornerstone to reach the destination. Every acceleration and turn of a yacht relies on the precise empowerment of the powerful "heart" — marine engine — under the hull. Cummins B4.5 and QSZ13 marine engines, crafted with ingenuity, guard every voyage with reliable quality, accompanying travelers to every blue paradise.

Cummins B4.5 marine engine is tailored for coastal cruising, delivering carefree navigation. Since entering China, this boat engine has become the preferred power solution for small and medium-sized yachts, favored by boat owners for its practicality and fuel efficiency. First installed on 36-foot yachts, B4.5 achieves an excellent balance between power output and fuel economy, supporting coastal cruising and fishing while controlling costs.

In core configuration, Cummins B4.5 marine engine is equipped with a dual-stage fuel filter (10-micron & 5-micron), forming a double protection for the engine. It filters fuel impurities accurately, ensuring stable power output and reducing injection system failures. Meeting US EPA Tier 3 standards without extra after-treatment, B4.5 simplifies installation and maintenance. Backed by Cummins' global service network, professional support and engine parts supply are accessible anywhere, guaranteeing worry-free voyages.

Li Qiuling, founder of Youde Yacht Co., Ltd.: "Low fuel consumption is a key factor for customers choosing a boat engine. Cummins' extensive global after-sales network ensures customers feel assured and worry-free, which is a testament to Cummins' quality and service."

For grand deep-sea expeditions, Cummins QSZ13 marine engine is an irreplaceable performance benchmark. As Cummins' first locally produced heavy-duty yacht engine, QSZ13 has gained excellent reputation at home and abroad. Suitable for 53-foot and above medium-to-large yachts, this marine engine empowers deep-sea navigation with cutting-edge technology, providing solid power for offshore exploration.

With lightweight design, QSZ13 marine engine boosts power-to-weight ratio by 41%, reducing hull weight while ensuring strong power, enhancing yacht maneuverability. Optimized fuel and transmission systems enable QSZ13 to deliver powerful power, low fuel consumption and excellent environmental performance, meeting CCS certification, C2 emission standards and IMO Tier 2, realizing harmonious coexistence of deep-sea navigation and ecology.

Local production is the biggest breakthrough of QSZ13 marine engine for China market. It reduces the cost of this Cummins marine engine, allowing more boat owners to enjoy high-end heavy-duty power experience. Meanwhile, it shortens delivery cycles and ensures timely supply of engine parts, solving pain points of imported marine engines such as slow after-sales and shortage of engine parts.

Deeply rooted in the yacht and cruise ships power market, Cummins has built a mature marine power matrix covering 4.5L to 13L engines, including B4.5 and QSZ13. Whether for coastal yacht cruising or deep-sea cruise ships voyages, small yachts or large luxury yachts, there is a perfectly matched Cummins marine engine power solution. Relying on world-class R&D and extensive service network, Cummins provides full-chain support for every yacht and cruise ship — from marine engine installation and commissioning, maintenance to engine parts supply. Cummins marine engines win market trust with reliable performance and professional services, creating carefree ocean voyages with powerful power.
