The case is all aluminum with included extra o rings for the water jacket. The bullet connectors fit like they should and this is serviceable. This is a 5mm shaft so an adapter was needed in my case but other than that cooling hoses were a direct fit along with mounting hole spacing lined up perfectly. Review: Great rc motor - 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 | B0BG867S2Y | | Best Sellers Rank | #119,454 in Toys & Games ( See Top 100 in Toys & Games ) #113 in RC Electric Motors | | Brand | Surpass Hobby USA | | Brand Name | Surpass Hobby USA | | Customer Reviews | 5.0 out of 5 stars 2 Reviews | | Horsepower | 5.71 hp | | Included Components | no | | Item Weight | 0.54 kg | | Manufacturer | SHENZHEN SURPASS TECH CO.,LTD | | Material | Aluminum, Metal | | Material Type | Aluminum, Metal | | Model | 1 | | Number of Items | 1 | | Part Number | 1 | | Speed | 920 rpm | | UPC | 768486240456 | | Voltage | 47 volts | ## Product Details - **Brand:** Surpass Hobby USA - **Horsepower:** 5.71 hp - **Material:** Aluminum, Metal - **Speed:** 920 rpm - **Voltage:** 47 volts ## Images ![Surpass Hobby 4092 920 KV Brushless Motor 4Pole Shaft 5mm with Water Cooling Jacket for RC Boat (920kv) - Image 1](https://m.media-amazon.com/images/I/61QpgjQ9FfL.jpg) ![Surpass Hobby 4092 920 KV Brushless Motor 4Pole Shaft 5mm with Water Cooling Jacket for RC Boat (920kv) - Image 2](https://m.media-amazon.com/images/I/61X4mPoyfsL.jpg) ![Surpass Hobby 4092 920 KV Brushless Motor 4Pole Shaft 5mm with Water Cooling Jacket for RC Boat (920kv) - Image 3](https://m.media-amazon.com/images/I/61Hx29aYTyL.jpg) ![Surpass Hobby 4092 920 KV Brushless Motor 4Pole Shaft 5mm with Water Cooling Jacket for RC Boat (920kv) - Image 4](https://m.media-amazon.com/images/I/71nAINPz23L.jpg) ![Surpass Hobby 4092 920 KV Brushless Motor 4Pole Shaft 5mm with Water Cooling Jacket for RC Boat (920kv) - Image 5](https://m.media-amazon.com/images/I/61MdLTycXVL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Dependable power *by H***B on August 18, 2023* Gives good performance on a budget.
