About Us

At Rong Marine, marine engines are more than products to us; they are part of the vessels people depend on every day offshore, commercially, and around the world. Our company was built from a genuine passion for marine propulsion systems, diesel engine technology, and helping customers find reliable solutions they can trust on the water.

Based in Hamburg, Germany, Rong Marine specializes in genuine Yanmar marine diesel engines, Volvo Penta marine engines, marine gearboxes, and propulsion solutions for yachts, fishing vessels, commercial boats, and marine repower projects worldwide. Over the years, we have worked with vessel owners, captains, shipyards, and marine professionals across Europe, the Caribbean, Africa, the Middle East, and international marine markets.

We understand that choosing the right marine engine is a major investment, and that many customers are not simply looking for a seller — they are looking for honest guidance, dependable support, and a company that understands real marine applications. That is why we take a practical and customer-focused approach to every project, helping customers with engine selection, gearbox compatibility, repower planning, shipping coordination, and technical support throughout the purchasing process.

At Rong Marine, we believe strong customer relationships are built through responsive communication, professional service, and real marine industry understanding. Whether you are sourcing a Yanmar diesel engine, planning a Volvo Penta repower, or searching for the right marine gearbox for your vessel, our goal is to help you move forward with confidence and long-term reliability offshore.
