Perhaps the most talked-about marine technology to hit the market in years, Swamp Shark has been designed to address the many weaknesses of other propulsion types. Developed and extensively tested in the unforgiving swamps of South Louisiana, Swamp Shark is a high performance propulsion system offering boaters the highest levels of handling and control across a wide range of conditions. A Swamp Shark drive offers many advantages over conventional propulsion systems. Metal Shark, a leading designer and manufacturer of welded aluminum boats for military, law enforcement, and commercial operators, is pleased to now offer Swamp Shark technology to recreational customers, too. Read on learn more about our rugged, go-anywhere, do-anything, military-tough Gravois 21 and 24 shallow-water boats powered by Swamp Shark.
There are lots of little mud boats out there with puny engines on them, struggling along at putt-putt speeds. Swamp Shark leaves them all in its wake. Swamp Shark handles up to 550 fire-breathing horsepower and a whopping 1,250 Ft.-Lbs. of torque so it’s capable of pushing a real boat – big enough for you, your friends, and all your gear – into even the most hostile terrain. Other options do not compare. Airboats offer high power but are meant to run in a straight line. Water jets require large water inlets that often clog, and outboards do, too. Other options have vulnerable appendages like rudders that snag in vegetation, or are so underpowered that they can’t get out of their own way. Swamp Shark offers the acceleration, speed, and handling of a propeller-driven vessel, it accommodates high power and torque loads, and travels in forward and reverse with equal proficiency. In short, Swamp Shark is the most durable and reliable shallow water propulsion system available.
The Swamp Shark propulsion system consists of several key components: A CNC-cut, machined-steel surface drive; internal/external hydraulic Rebound System; and a specialized internal cooling system, all of completely original design. The patented Rebound System, which consists of actuators inside and outside of the vessel, allows the Swamp Shark drive to smoothly and automatically adapt to conditions. When the drive impacts a solid object, such as a log, stump, or other submerged hazard, it swiftly and smoothly “kicks up” so that the propeller will not be impacted (the leading edge of the skeg features a special radius designed to facilitate quick and smooth passage over any objects it encounters). The Rebound System then exerts reverse pressure to instantaneously return the drive to its normal trim position as soon as the object has been cleared.
Swamp Shark features a fully self-contained, patent-pending, onboard keel cooling system, with no appendages beneath the hull, to enable smooth and reliable operation over underwater obstacles. Since there is no need for outside water, a Swamp Shark-propelled vessel can traverse shallow, vegetation-clogged water or even loose mud with no cooling issues. This highly-efficient system cools engine oil, power steering and transmission fluid, and also boost-air intercoolers for turbo or supercharged engines, all with no reliance on outside water. A Swamp Shark exclusive!

We invite you to contact us to begin the process of building your very own Metal Shark powered by Swamp Shark.
Each Metal Shark Swamp Shark offering is the result of 100% digital design. The process begins with Metal Shark’s in-house team of over 35 naval architects and marine engineers, who model every single component of a Swamp Shark vessel using the latest parametric modeling software. Details as minute as the threads on each fastener are included in the digital design, allowing the boat to be fully realized in 3D prior to construction. Cut files are nested and transmitted digitally to CNC routers, which then cut each and every aluminum component to exacting standards. Highly trained welders then assemble each boat, turning plates of aluminum into durable, long lasting works of high performance art. Quality Assurance procedures honed in concert with US Navy and Coast Guard inspectors assure consistent quality output. The result is a repeatable design that may be consistently produced, assuring that each Metal Shark hull will perform exactly as intended.
