I build model RC machines, including boats and this motor will be perfect for my larger builds. I tested this with a 40mm prop on a 3s pack and it performed well. The included water cooling jacket is a nice bonus and even comes with spare O-Rings. Be sure to use at the very least an 80a ESC, preferably 100a+ with this motor. I'm running an 80a ESC, which should be fine as long as I don't WOT this motor for extended periods. Review: Perfect motor upgrade for my rc boat. Can't wait to install it and rip up the Lake with this beastly motor. I did a mock up and the size is just right. Motor is sturdy and strong, well built with 4 poles and a water cooled heatsink. Overall really nice and powerful rc boat motor. ## Features - 【Brushless RC Boat Motor】This motor is designed for 650-800mm Boat.Exquisite shape and exquisite craftsmanship, Surpass hobby boat motors are engineered to provide maximum power and cooling for your RC watercraft. - 【4 Poles Design】4 poles design ensures high torque & high efficiency, offers the ship much faster acceleration response and stable output of power,The overall efficiency exceed 95 percent. - 【Good Heat Dissipation】This is made of high-quality aluminum alloy and copper with cooling set, use advanced processing technology ensures good heat dissipation,which is durable and has a long service life. - 【Low Noise】High RPM ABEC5 Oversized Bearings, Superior bearing is precision and durable with low noise and small friction to achieve the best reliability and maximum RPM. - 【High Grade Material】 Made of metal material, the motor with durable shell, advanced rotor structure, high-quality shaft, high-precision bearings ,Durable, Corrosion Resistant and Great looks. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BG84G9B4 | | Best Sellers Rank | 483,705 in Toys & Games ( See Top 100 in Toys & Games ) 1,053 in Model Building Motors | | Brand | Surpass Hobby USA | | Customer Reviews | 4.8 4.8 out of 5 stars (8) | | Horsepower | 930 Kilowatts | | Included Components | no | | Item Dimensions W x H | 38W x 38H millimetres | | Item Weight | 0.49 Kilograms | | Manufacturer | SHENZHEN SURPASS TECH CO.,LTD | | Material | Aluminium, Copper, Metal | | Model Number | 1 | | Speed | 930 RPM | | UPC | 768486240272 | | Voltage | 12 Volts | ## Product Details - **Brand:** Surpass Hobby USA - **Horsepower:** 930 Kilowatts - **Product dimensions:** 38W x 38H millimetres - **Speed:** 930 RPM - **Voltage:** 12 Volts ## Images ![Rocket 4082 930KV Brushless RC Boat Motor Waterproof Brushless Motor 4Pole Design Replacement Boat Parts(930kv) - Image 1](https://m.media-amazon.com/images/I/61sYEZJXnmL.jpg) ![Rocket 4082 930KV Brushless RC Boat Motor Waterproof Brushless Motor 4Pole Design Replacement Boat Parts(930kv) - Image 2](https://m.media-amazon.com/images/I/61X4mPoyfsL.jpg) ![Rocket 4082 930KV Brushless RC Boat Motor Waterproof Brushless Motor 4Pole Design Replacement Boat Parts(930kv) - Image 3](https://m.media-amazon.com/images/I/61Dzs01TI+L.jpg) ![Rocket 4082 930KV Brushless RC Boat Motor Waterproof Brushless Motor 4Pole Design Replacement Boat Parts(930kv) - Image 4](https://m.media-amazon.com/images/I/71PEaVyZ2kL.jpg) ![Rocket 4082 930KV Brushless RC Boat Motor Waterproof Brushless Motor 4Pole Design Replacement Boat Parts(930kv) - Image 5](https://m.media-amazon.com/images/I/618C4JDGJCL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***I on 22 June 2023* This is by far the largest BLDC motor I own.
