Overview
The UDI RC INKFISH STEERING GEAR UDI023-20 is a high-torque waterproof servo component designed specifically for the UDI023 Inkfish JetBoat, a sophisticated 362mm remote control jet boat that combines cutting-edge engineering with exceptional water-based performance. This 9g integrated waterproof steering gear is engineered to deliver precise directional control in demanding aquatic environments, making it an essential component for anyone operating a brushless RC jet boat in the UK or beyond. Whether you're a dedicated RC enthusiast looking to repair or upgrade your existing Inkfish JetBoat, or building a ready to run RC model from spare parts, this steering gear represents genuine OEM quality from UDI RC TECHNOLOGY CO., LTD, the original manufacturer.
The Inkfish JetBoat itself is renowned in the RC hobby community for its innovative jet pump propulsion system, shallow V-shaped hull design, and ability to navigate freely in shallow and rocky water areas without fear of collision or entanglement with underwater obstacles. The steering gear is absolutely critical to this performance, as it controls the directional nozzle that guides the water jet, allowing precise steering inputs from your 2.4GHz radio control system. This waterproof servo has been specifically selected and integrated into the UDI023 design to withstand the rigorous conditions of water-based RC operation, including exposure to moisture, salt spray, and rapid temperature changes that would quickly damage standard terrestrial RC servos.
If you own an Inkfish JetBoat or are considering purchasing one, having a genuine replacement steering gear on hand is a smart investment in your RC equipment. This component is available as a standalone spare part through RC Model Shop, allowing you to maintain your jet boat in peak condition and minimise downtime due to servo failure or wear.
Key Features
- 9g Integrated Waterproof Design — This servo is specifically engineered with waterproof sealing to protect all internal electronics from water ingress, moisture damage, and corrosion. This is essential for RC jet boat operation where the servo is exposed to splash, spray, and humid aquatic environments that would rapidly destroy a standard terrestrial servo. The waterproof construction ensures reliable long-term performance in conditions that would normally cause servo failure within weeks.
- High Torque Output — The steering gear delivers sufficient torque to precisely control the directional water jet nozzle even under full throttle conditions, ensuring responsive and accurate steering inputs that translate directly to on-water performance. High torque is critical for jet boat steering as the servo must counteract the force of pressurised water flow through the directional nozzle while maintaining smooth, predictable handling characteristics.
- OEM Quality and Compatibility — This is the genuine original equipment manufacturer steering gear specified and supplied with the UDI023 Inkfish JetBoat models. It is engineered to integrate perfectly with the Inkfish hull design, mechanical linkages, and electronic control systems. Using genuine OEM components ensures that your jet boat performs exactly as the designers intended, with no fitment issues or performance compromises.
- Reliable Performance in Water-Based RC Operation — Unlike standard RC servos that require expensive waterproofing modifications and aftermarket sealing, this steering gear arrives factory waterproofed and tested for aquatic environments. This eliminates the guesswork and expense of trying to make terrestrial servos water-resistant, while guaranteeing reliable operation throughout the lifespan of your RC jet boat.
Technical Performance
The UDI023-20 steering gear is specifically engineered for the Inkfish JetBoat's jet pump propulsion system and shallow V-shaped hull design. At 9g weight with integrated waterproof construction, this servo balances responsiveness with durability in one compact package. The high-torque specification ensures that directional control inputs are crisp and immediate, which is essential for precision steering of a jet-driven RC boat operating at speeds up to 20 km/h. The Inkfish JetBoat utilises a 2.4GHz radio control system with a 4-channel receiver that features built-in gyroscope stabilisation, and this steering gear integrates seamlessly with that control architecture to deliver smooth, predictable directional response. The servo's waterproof rating makes it suitable for operation in shallow water, rocky areas, and various aquatic conditions where standard RC equipment would fail. Built to the same engineering standards as the rest of the Inkfish system, which includes a water-cooled brushless motor option, marine-grade ESC with innovative waterproof design, and balanced lithium battery power system, this steering gear is part of a comprehensively engineered RC jet boat platform that prioritises reliability and performance in demanding water-based environments.

Frequently Asked Questions
- Is the UDI023-20 steering gear compatible with other RC boats or just the Inkfish JetBoat? — This steering gear is specifically designed and engineered as an OEM component for the UDI023 Inkfish JetBoat. Whilst the servo specifications may theoretically fit other applications, it is optimised for the Inkfish's mechanical linkages, directional nozzle design, and control system integration. For best results and guaranteed compatibility, we recommend using this servo only as a replacement for the original Inkfish steering system.
- What is the difference between this steering gear and a standard RC servo? — Standard RC servos are designed for land-based vehicles and do not feature waterproof construction or sealing suitable for continuous water exposure. This UDI023-20 steering gear is purpose-built with waterproof integrated design to protect against moisture ingress, corrosion, and water damage. It is also calibrated to the specific torque requirements of the Inkfish jet pump steering system, making it far superior to aftermarket alternatives for this application.
- Do I need to apply any additional waterproofing or protective coatings to this steering gear? — No. This steering gear arrives fully waterproofed from the factory and requires no additional sealing, coating, or modification. Simply install it as a direct replacement for the original servo in your Inkfish JetBoat, and it is ready for immediate use in water. The integrated waterproof design eliminates the need for expensive aftermarket waterproofing treatments.
- How long will this steering gear last when used regularly on my RC jet boat? — With proper maintenance and care, the waterproof construction of this OEM steering gear provides extended lifespan compared to standard servos exposed to water damage. The integrated sealing protects internal electronics and mechanical components from corrosion and moisture-related wear. Regular freshwater rinses after saltwater use and proper storage will maximise longevity. As with all RC servo components, eventual wear is natural, but quality waterproof construction ensures reliable performance over many seasons of active use.
- What radio control system does this steering gear work with? — The UDI023-20 is integrated into the Inkfish JetBoat system, which features a 2.4GHz radio control system with a 4-channel receiver. The steering gear responds to standard proportional servo signals from this receiver, allowing smooth directional control across the full range of steering inputs. It is compatible with the UA37 wireless control system supplied with the Inkfish.
