The New Sturgeon 200 Thruster
New Modular Propulsion System Brings Unmatched Efficiency and Adaptability to Underwater Vehicles
NANAIMO, BC – April 24, 2025 – SEAMOR Marine, a leading innovator in underwater technology, recently announced the launch of its new Sturgeon 200 thruster, a powerful modular propulsion system, with integrated speed control, designed for remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), and unmanned surface vessels (USVs).
Named after the sturgeon fish for its power, adaptability, and longevity, the new thruster builds on SEAMOR Marine’s twenty years of product design expertise. The Sturgeon 200 is available in a standard 24-volt configuration, with 48-volt options for applications requiring additional power.
“The development of the Sturgeon 200 thruster exemplifies our commitment to collaboration with customers and partners to create solutions that address real-world challenges,” said Inja Ma, CEO of SEAMOR Marine. “Every innovation we pursue is guided by our core mission to protect the health of our oceans for future generations, which is why efficiency and reliability are central to the Sturgeon’s design.”
What distinguishes the Sturgeon 200 from competing models is its impressive combination of power and efficiency, offering exceptional propulsion while consuming almost half the power of standard industry alternatives. This remarkable efficiency makes the thruster particularly well-suited for AUVs and USVs, where power conservation is critical.
The Sturgeon 200 thruster features a Swiss-designed Maxon Motor delivering clock-like precision and exceptional responsiveness. Its electrical components are protected by a BAL Seal nose cone assembly—the same technology used in NASA spacecraft—and housed in a high-strength, corrosion-resistant 6061 Aluminum casing that avoids the pitfalls of fully-flooded or magnetically coupled designs common in other units.
“The Sturgeon 200 thruster represents our unique promise of serviceability versus disposability,” explained Robin Li, President of SEAMOR Marine. “Its modularity and versatility aren’t just technical features—they’re a reflection of our commitment to reliability and sustainability. The easy-to-maintain design with replaceable shaft seal cartridge means these thrusters are built to last and be serviced, not discarded, which is better for both our customers and our planet.”
User-friendly features include right and left-handed custom-made props, a built-in electronic speed controller, and real-time data feedback to optimize performance. The system’s onboard motor control circuitry and RS-485 interface with flexible communication protocol allow for seamless integration, enabling users to have a complete system operational within minutes.
These practical features have already made SEAMOR Marine thrusters the propulsion of choice for the company’s flagship ROV units, including the Chinook, Steelhead, and Mako models.
Backed by SEAMOR Marine’s renowned product development and service team, the Sturgeon 200 comes with the company’s commitment to responsive customer support—a benefit frequently highlighted by clients and operators.
