Tugboats with Detroit Diesel 12V71s — Why Diesel Pro Power Is the Trusted Source for Rebuilds and Parts (Featuring Hempstead Marine Video)
There’s something unmistakable about the deep, throaty rumble of a Detroit Diesel 12V71at work. It’s the sound of raw power, reliability, and marine engineering done right. For decades, these engines have powered tugboats, workboats, and heavy-duty marine vessels all over the world — engines that don’t just move cargo, but move industries.
In the Hempstead Marine tugboat video, you can see this power in action — a perfect example of how the Detroit Diesel 12V71 continues to prove its worth year after year. And behind every engine that performs like this is one thing: quality parts, precision service, and proper maintenance.
That’s where Diesel Pro Powercomes in.
We specialize in keeping Detroit Diesel engines — including the legendary 12V71 — running strong, reliable, and efficient. Whether you’re maintaining a fleet of tugboats or restoring a single engine, Diesel Pro Power provides the rebuilt parts, components, and technical expertise to keep your vessel working at its peak.
The Power Behind the Tugboat: Detroit Diesel 12V71
The Detroit Diesel 12V71 is more than an engine — it’s an icon of marine power. Built on the trusted 71 Series platform, it’s a two-stroke V12 diesel enginewith 12 cylinders displacing 71 cubic inches each, giving it a total of 852 cubic inches (14 liters). Depending on configuration, it delivers anywhere from 400 to 850 horsepower— with the kind of low-end torque that marine operators depend on to push or pull with precision in rough conditions.
These engines earned their reputation in commercial and industrial settings where failure simply isn’t an option. In tugboats, where torque and reliability are everything, the 12V71 became the gold standard. Even decades after their introduction, many operators still rely on them — not because they’re nostalgic, but because these engines still outperform newer systems in durability and serviceability.
The Hempstead Marine videocaptures that legacy perfectly — twin 12V71s roaring in sync, effortlessly pushing a fully loaded tug through the water. It’s a demonstration of mechanical strength and endurance — and a testament to what happens when quality parts meet expert craftsmanship.
