Product description
The DW25 is the most powerful thruster in the DW series. Designed for medium to large ROVs and AUVs, it produces at least 25 kgf of static thrust at a rated 48 V with about 1315 W of continuous power, and works down to 350 meters. It is the highest-thrust option CubeMars offers for power-hungry heavy missions and complex marine environments.
Key features
- Highest thrust in the series. At least 25 kgf of static thrust suits vehicles carrying heavy payloads or holding position in strong currents.
- High-power configuration. About 1315 W of continuous power on a 48 V system keeps thrust consistent under load.
- 350 m depth. Validated down to 350 meters for demanding marine missions such as inspection, salvage and scientific survey.
- Robust build. The precision-cast aluminum alloy housing resists corrosion and impact. Dual sealed chambers and a low-friction dynamic shaft seal keep sand, silt and seawater out.
- Heavy-gauge cable. A 1.5 m, Ø9.5 mm TPU-jacketed 3 x 12 AWG cable carries the higher current.
Applications
Typical applications include large unmanned underwater platforms, medium and large ROVs, underwater salvage and inspection vehicles, scientific survey AUVs, unmanned surface vehicles (USVs) and electric surfboards.
Is it enough for your project?
A single DW25 delivers at least 25 kgf of static thrust. For example, if two DW25 units on a vehicle face straight forward, forward static thrust is at least 50 kgf. This leaves more margin than the DW20 for high-drag hulls or vehicles working against a current. Actual speed depends on the vehicle's drag and tether load.
The housing measures Ø152 x 191 mm and weighs 1790 g, about 995 g in water. The propeller is Ø126 mm and the motor rotor has 20 poles. Operating temperature is 0 °C to 40 °C. If your thrust need is around 20 kgf, the lower-power DW20 may be enough.
How it compares to similar models
- DW20. Same Ø152 mm housing diameter and Ø126 mm propeller, 910 W and at least 20 kgf of thrust. The housing is 182 mm long and it weighs 1630 g.
- SW17. The most powerful SW model. 17 kgf of thrust at 870 W, 1350 g, limited to 30 m depth.
- DW15. 750 W and at least 15 kgf of thrust. With a Ø130.6 mm housing and 1260 g it is smaller, and it pairs with the TW-40A-12S ESC.
Frequently asked questions
Which ESC does it work with?
The DW25 runs with an external driver. The pairing CubeMars recommends is the TW-80A-12S underwater ESC, which is also compatible with the SW17 and DW20.
How should the power supply be sized?
The thruster runs on a rated 48 V and draws about 1315 W continuously. Battery and cable gauge should be chosen with the number of thrusters running at the same time in mind. Our team can support you with power system design.
Can it be used in seawater?
Yes. The housing resists corrosion and the sealing design keeps seawater out of the motor chamber. The manufacturer recommends rinsing with clean water after each use.
Are mounting parts included?
Yes. The box contains two mounting bases, a connecting rod and screws in three sizes. CubeMars also publishes a 3D drawing of a shared mounting bracket for the DW20 and DW25.

Frequently asked questions
The most common questions about motor selection, delivery and technical support.
Is the product in stock and when is it dispatched?
Our products ship from our own warehouse in Turkey. Your order is dispatched within 3 business days. Current stock status is shown on this page.
Which motor fits my project? Can you help me choose?
Yes. Tell us the torque, speed and supply voltage you need, and we will find the right series together. You can also compare using the specifications table on this page and the filters on the category page.
- For high torque at low speed, the AK, AKE and AKH series with gearbox
- For direct drive and low inertia, the frameless RI and RO series
- For cameras and stabilization systems, the GL series
Are the products genuine and under warranty?
Robotizma is an official CubeMars distributor. Every product we sell is genuine and covered by the manufacturer's warranty.
Where can I find the datasheet and mounting dimensions?
The Specifications section on this page lists rated torque, peak torque, KV, no-load speed, weight and outer dimensions. If you need the detailed datasheet, CAD file or driver documentation, ask our technical team.
Do you offer corporate sales, quotes and invoices?
We sell to universities, industry and R&D projects. For volume pricing and a formal quote, fill in the Request a quote form on this page and our team will reply with price and delivery details.
Which driver and communication can I use with the motor?
In the AK and AKH series actuators the driver board is built into the motor and communicates over CAN. The AKE series and the frameless RI and RO series motors need an external FOC driver. The R-Link and S-Link interfaces are for setup and debugging, and we can support you during installation.
