Its corrosion-resistant nylon fiber glass composite housing and high-precision bearings ensure long-lasting performance for ROVs, RC boats, and underwater exploration. Designed for easy modular assembly, this thruster balances power, durability, and efficiency for professional-grade aquatic applications. ## Description Parameter：Input voltage：12V----14.8V Current：13A Motor size：28MM*38MM Thruster size：78*112MM Motor KV：350KV Thrust forward：1200g----2500g Rated current：5A---13A Power：60W---312W Thrust size：Diameter 78mm, length 112mm, signal wire 500mm, cover nylon injection moulding anti corrosion Component includes deflecting cover and cap, propeller(CW or CCW), ESC, motor, cable Package included： 1 x Underwater Thruster (CCW) 1 x ESC 4 x Screw Review: Check function before assembly - Waterproof construction seems solid, easy to install. Sometimes requires a couple of throttle cycles at first run to get the ESC behaving properly (I have noticed they will make some odd noises the first thrust and then normalize the second time) but otherwise seem fine and good value for the price. I ordered 6 of these (3 CW 3CCW) for a UAV project. I wish I had tested these when I received them, because 2 out of 6 had faulty ESCs. Not complaining about customer service, I didn't try to return them because I'd already installed them into my drone and water-sealed them to the hull, but if I had not done that I would have returned the bad ones for replacement Review: Able to propel a 15' canoe - Two trustees and a car battery. Able to move at a fair pace in still water and 1-7mph wind. Plan to check current draw the next time out out of water test under load 4 amps. I also plan to mount under the canoe for better speed. ## Features - Compact mold design：Nylon fiber glass composites, which is of good mechanical properties and anti corrosion - Full waterproof technique, water resistant up to 100 meters，Motor encapsulated technology, long last working underwater - Accompany with high performance bi-directional full waterproof ESC，High precision baring prolongs the motor life，PWM：1500-2000us(forward)，1500-1000us(backward) - Reasonable power combination for high efficiency，Propeller made by powerful composite material, to have the best matched motor for the top efficiency - Easy assemble：Modularized base, meeting with different field requirement - Included components: nothing ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09BVKB3KD | | Best Sellers Rank | #206,124 in Toys & Games ( See Top 100 in Toys & Games ) #344 in RC Electric Motors | | Brand | DIAMONDDYNAMICS | | Brand Name | DIAMONDDYNAMICS | | Color | Black | | Customer Reviews | 3.8 out of 5 stars 15 Reviews | | Engine Type | electric | | Fuel Type | electric | | Manufacturer | DIAMONDDYNAMICS | | Manufacturer Part Number | TD1.2 | | Material | Plastic | | Material Type | Plastic | | Maximum Horsepower | 312 Watts | | Model Number | TD1.2 | | Mounting Type | Transom Mount | | Operation Mode | Automatic | | Recommended Uses For Product | For Fishing Boats, For Seafloor | | UPC | 781855994873 | | Voltage | 24 Volts | ## Product Details - **Brand:** DIAMONDDYNAMICS - **Engine Type:** electric - **Material:** Plastic - **Operation Mode:** Automatic - **Recommended Uses For Product:** For Fishing Boats, For Seafloor ## Images ![DIAMONDDYNAMICS Underwater Thruster 1.2kg Thrust 12V Brushless Motor with bi-Directional Full Waterproof ESC for ROV,RC Boat,Underwater Vehicle,Diving,Seafloor Photography,Seabed Exploration (CCW) - Image 1](https://m.media-amazon.com/images/I/61zv4ThSbcL.jpg) ![DIAMONDDYNAMICS Underwater Thruster 1.2kg Thrust 12V Brushless Motor with bi-Directional Full Waterproof ESC for ROV,RC Boat,Underwater Vehicle,Diving,Seafloor Photography,Seabed Exploration (CCW) - Image 2](https://m.media-amazon.com/images/I/61Id3UiQRPL.jpg) ![DIAMONDDYNAMICS Underwater Thruster 1.2kg Thrust 12V Brushless Motor with bi-Directional Full Waterproof ESC for ROV,RC Boat,Underwater Vehicle,Diving,Seafloor Photography,Seabed Exploration (CCW) - Image 3](https://m.media-amazon.com/images/I/81YAu+AW9XL.jpg) ![DIAMONDDYNAMICS Underwater Thruster 1.2kg Thrust 12V Brushless Motor with bi-Directional Full Waterproof ESC for ROV,RC Boat,Underwater Vehicle,Diving,Seafloor Photography,Seabed Exploration (CCW) - Image 4](https://m.media-amazon.com/images/I/41o6TScmGML.jpg) ![DIAMONDDYNAMICS Underwater Thruster 1.2kg Thrust 12V Brushless Motor with bi-Directional Full Waterproof ESC for ROV,RC Boat,Underwater Vehicle,Diving,Seafloor Photography,Seabed Exploration (CCW) - Image 5](https://m.media-amazon.com/images/I/81WXiGj+5lL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: What is the power of the motor?** A: 2.2 mph with a 15 ft canoe. That's the best I got at the moment. **Q: What screws are used for mounting the thruster? They are unlisted here, and in the package contents.** A: Hello! Thank you for your question. There are four installation holes in our product picture. In addition, we provide videos for your reference. **Q: could I use this as a little underwater jetpack?** A: Yes, you should match the waterproof battery and the condition switch of PWM signal. **Q: what speed controller to use? and how to get the missing 5V signal to the speed controller?** A: The speed controller is included. This just takes the motor power and a control signal. You don't need to connect up a separate 5V. However, you will need to share ground between the motor supply and you receiver or whatever generates the control signal. ## Customer Reviews ### ⭐⭐⭐ Check function before assembly *by R***N on March 15, 2026* Waterproof construction seems solid, easy to install. Sometimes requires a couple of throttle cycles at first run to get the ESC behaving properly (I have noticed they will make some odd noises the first thrust and then normalize the second time) but otherwise seem fine and good value for the price. I ordered 6 of these (3 CW 3CCW) for a UAV project. I wish I had tested these when I received them, because 2 out of 6 had faulty ESCs.

Able to move at a fair pace in still water and 1-7mph wind. Plan to check current draw the next time out out of water test under load 4 amps. I also plan to mount under the canoe for better speed. ### ⭐ Dont buy unless you don't need instructions that are correct. *by A***R on July 23, 2023* Product arrived in generic white box(which was open) with no paperwork or instructions. It comes with a motor and 4 screws. Nothing else. The "instructions" on the Amazon page are flat out wrong. There is a white wire that comes out of the motor but it is not reference in the "instructions". I decided rather than cross-wiring it and burning the thing up, its easier to return and never buy this brand again. You would think whomever is managing this category at Amazon would have the novel thought of requiring correct instructions. ## Frequently Bought Together - DIAMONDDYNAMICS Underwater Thruster 1.2kg Thrust 12V Brushless Motor with bi-Directional Full Waterproof ESC for ROV,RC Boat,Underwater Vehicle,Diving,Seafloor Photography,Seabed Exploration (CCW) - 2 Pairs XT60 Plug Male Female Connector to T Plug Male Female Connector Conversion Adapter - SUPULSE LiPo Battery Charger 2S-3S RC Balance Charger AC 7.4-11.1V 10W Upgrade Version Compact Lipo Charger RC Car Charger for XHR Plug Battery(B3V2) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/355830768-diamonddynamics-underwater-thruster-1-2kg-thrust-12v-brushless-motor-bi](https://www.desertcart.hr/products/355830768-diamonddynamics-underwater-thruster-1-2kg-thrust-12v-brushless-motor-bi) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-14*
