How much thrust can be added without growing the vehicle? That is the question CubeMars poses - and answers - in the official DW25 underwater thruster showcase: up to 25 kgf of static thrust from a unit weighing just 1.79 kg.

What the Video Shows

The video documents real validation rather than renders: the DW25 is tested in a water tank and in an outdoor pond, demonstrating stable thrust output, smooth bidirectional control and the corrosion-resistant construction intended for demanding marine service. CubeMars positions the DW25 for ROVs, AUVs and underwater inspection platforms where efficiency, reliability and space utilization are critical.

Engineering Context

Thrust-to-weight ratio drives everything in small subsea vehicles: more thrust per kilogram means heavier payloads, better station-keeping and stronger maneuvering against currents. A 25 kgf / 1.79 kg unit is a strong data point for inspection-class ROVs that need to hold position in moving water without ballooning in size.

Conclusion

The DW25’s tank-and-pond validation is exactly the kind of evidence subsea engineers look for: real thrust, real water, real durability claims backed by footage. Full specifications and the product page are available on ToBMS.
