Proven Reliability, Global Support, and Cruising Confidence
Many sailors have their own “Yanmar story.” For me, it began during a major transition in life when I purchased a well-loved 1976 sailboat powered by its original four-cylinder Yanmar diesel engine. Despite its age, the engine started reliably, ran smoothly, and asked for very little in return beyond clean fuel, regular oil changes, and routine maintenance. That experience left a lasting impression and confirmed what countless cruisers around the world already knew—Yanmar engines are built to last.
It’s one of the reasons Yanmar continues to power every Leopard sailing and power catamaran today.
Over a Century of Marine Engineering
Since introducing the world’s first practical small diesel engine in 1933, Yanmar has spent decades refining marine propulsion technology with an emphasis on reliability, fuel efficiency, quiet operation, and long-term durability.
Modern Yanmar common-rail diesel engines offer smoother performance, lower emissions, reduced vibration, and improved fuel economy while remaining remarkably simple to maintain. Their reputation for dependability has made them one of the most trusted engine manufacturers among cruising sailors worldwide.
Why Leopard Chooses Yanmar
Selecting an engine partner is about far more than horsepower. Leopard Catamarans builds boats designed for coastal cruising, offshore passages, and circumnavigations, meaning owners need propulsion systems they can rely on almost anywhere in the world.
Today’s Leopard lineup—including the Leopard 43, Leopard 46, Leopard 52, Leopard 40 PC, Leopard 46 PC, and Leopard 53 PC—is powered by Yanmar diesel engines because they combine proven performance with one of the industry’s largest global support networks.
With authorized dealers and service centers in more than 130 countries and territories, owners can find parts, maintenance, and qualified technicians whether they’re cruising the Bahamas, crossing the Pacific, or exploring the Mediterranean.
Designed for Modern Leopard Catamarans
On Leopard sailing catamarans, Yanmar engines are paired with efficient saildrive systems and are installed in dedicated engine compartments located in the aft transoms. This arrangement maximizes living space while providing excellent service access and reducing noise inside the cabins.
Leopard power catamarans utilize larger Yanmar engines with straight-shaft propulsion systems designed for higher cruising speeds and exceptional reliability. Dedicated engine rooms provide easy maintenance access while extensive insulation helps minimize vibration and engine noise underway.
Easy Maintenance Wherever You Cruise
One of Yanmar’s greatest strengths is its straightforward maintenance schedule.
Routine service items—including oil changes, filters, impellers, belts, and fuel system maintenance—are well documented and supported worldwide. Because Yanmar engines are so widely used throughout the recreational and commercial marine industries, replacement parts are readily available in many of the world’s most popular cruising destinations.
For owners planning extended voyages, that accessibility provides invaluable peace of mind.
Built for a Lifetime of Cruising
Many Leopard owners purchase their yacht with dreams of sailing far beyond their home waters. Whether exploring the Caribbean, cruising the Mediterranean, or embarking on an offshore adventure, dependable propulsion is essential.
The long-standing partnership between Leopard Catamarans and Yanmar gives owners confidence that their engines are backed by decades of engineering expertise, worldwide service support, and a reputation earned through generations of cruising sailors.
When your adventures take you far from home, knowing your engine is designed to go the distance makes all the difference.
