Control of an inflatable boat with a tiller engine is effective only at low speeds and in calm water. However, once you plan more serious exits, long crossings or fishing when you are excited, the standard handle becomes a real test for the hands and back. steering It drastically changes the ergonomics and safety of swimming, allowing you to control the course with minimal effort.
The current market offers many solutions tailored specifically for PVC hulls. Unlike hard-transe boats, it requires specific approaches to fastening and force transfer. The wrong choice of components can lead not only to discomfort, but also to damage to cylinders or squirrel boards. So it is important to understand the types of actuators and materials from which they are made.
In this article we will discuss in detail which cockpit So, if you're going to fit your boat, look at the nuances of the installation, and compare the popular models, you'll learn why hydraulics often beats the mechanics on high-powered engines, and how to avoid common system assembly errors, and if you upgrade your PVC boat properly, you'll be able to make a full-fledged small boat with a high level of comfort.
Why you need steering on a PVC boat
The main reason for the switch to the steering wheel is physical fatigue, and when driving a tiller on engines from 15 hp and above, especially against wind or wave, the hands are constantly under strain. Steering gear It takes that load on itself by fixing the position of the motor and letting the operator relax, which is critical for safety, because the tired person reacts more slowly to danger.
And the steering wheel also frees up the other hand, and the fisherman can use the gear, the sonar or the navigator without letting out the tiller, and the tourists can control one hand and hold the map or binoculars with the other, and the improvement in visibility is also worth noting: sitting on a can or in a chair, you see more than standing at a transom and hunched over the motor.
⚠️ Attention! The rudder shifts the center of gravity and changes the sailing of the vessel. On light inflatable boats with one cylinder, sharp turns at high speed can lead to a tipping over. Always consider the stability of your boat.
Another important aspect is the ability to install a windscreen and a tent-transformer. Without a remote steering wheel, it is almost impossible to organize a full windshield space. The coil allows you to create a comfortable cabin that protects against splashes and oncoming airflow, which is especially important in the cold season or during long transitions.
Types of steering mechanisms: mechanics versus hydraulics
When choosing a control system, you will face a dilemma: mechanical cable drive or hydraulic. Mechanical steering wheels (often called "tether in the casing") are the most common budget option, and they are a steel cable encased in a flexible shell that transfers the steering wheel to the rotating mechanism of the motor, which are easy to install and maintain, but have one major drawback: backlashes and friction, which grow with the length of the cable.
Hydraulic systems They work by transmitting fluid pressure in a closed loop. There are no rubbing metal parts at the force transfer points, which ensures smooth running and no backlashes. Hydraulics are ideal for high-power motors (50 hp and above), where the mechanical cable can not withstand the load or work too tight. However, the cost of such kits is much higher, and they require more attention to the tightness of the connections.
There is also a division by type of mounting of the steering wheel itself: For inflatable boats, the most relevant removable console racks or mounting systems to the transom board. Stationary inverter rudders in PVC board are not installed because of the inability to ensure rigidity of the structure. The choice between types of drive often depends on the budget and power of your outboard motor.
- 🔧 Mechanics: affordable price, ease of repair, suitable for engines up to 40-50 hp
- 💧 Hydraulics: perfect smoothness, lack of backlashes, reliability on powerful engines, high price.
- ⚖️ Combined systems: a rare option where hydraulics are used only to facilitate rotation, and fixation is mechanical.
The Myth of Homemade Hydraulics
Many enthusiasts are trying to assemble a hydraulic steering wheel from car brake cylinders. It's dangerous! Specialized marine hydraulics are designed to work in aggressive environments and have a margin of safety that can not be achieved by artisanal methods. Leakage of brake fluid into water is prohibited by eco-standards, and loss of control on water can cost lives.
Criteria of choice: what to pay attention to
The first and foremost parameter is compatibility with your motor. outboard For most modern Yamaha, Mercury, Tohatsu and Honda models, there are special transition plates (steering thrust) that replace the standard crank of the crank. Make sure that the steering kit you choose includes the necessary traction or the ability to buy it separately.
The second critical factor is the length of the cable or hose. Inflatable boats, the length usually varies from 3 to 4 meters. If the boat is large, with the console far from the transom, lengthening may be necessary. Remember, for mechanical cables, there are limits on the minimum bend radius. You can not bend the cable drive with a radius of less than 20-25 cm, as this will lead to jamming of the cable inside the casing and failure of the system.
Materials also play a role. Coils are often made of stainless steel or coated aluminum. Plastic elements must be made of marine plastic that is resistant to ultraviolet light. Cheap analogues can burn out and become brittle in one season. Pay special attention to the quality of seals and gums if you choose hydraulics.
| Parameter | Mechanical drive | Hydraulic actuator |
|---|---|---|
| Cost | Low/Mediocre | High. |
| Installation | Simple, yourself. | Requires system pumping |
| Service | Lubrication of the cable once a season | Checking fluid levels |
| Resource | 3-5 years of active operation | 10+ years |
Overview of popular models and brands
The leader of the control systems market for small craft is traditionally considered to be an American company. Teleflex Marine (SeaStar brand) Their mechanical cables in the SSC series are considered the gold standard of reliability. For inflatable boats, they often offer ready-made kits including a steering wheel, a cable and a fastener, a choice for those who don't want to skimp on safety and are willing to pay for proven quality.
The more accessible segment includes Chinese brands such as HDW or Yamaha They offer functional counterparts that are perfectly capable of handling medium-powered motors, and they may be inferior to top brands in plastic and coating, but they last a long time when operated carefully, often as an option from the PVC boat manufacturers themselves.
We also have to mention Russian adapters and thrusts. Because we have a very developed PVC boat market, local manufacturers have learned to make excellent transition units for installing the steering wheel on Honda, Tohatsu and Suzuki engines. Buying a local adapter is often cheaper than ordering the original thrust, and they are not inferior in functionality.
When buying a mechanical cable, take a length with a margin of 30-50 cm Extra cable can be carefully rolled up and fixed under the console, but the missing piece cannot be built up without loss of reliability.
Step-by-step instructions for installing the steering wheel
The installation process requires accuracy and a basic set of tools. Before starting work, make sure that the thrashboard of your boat is reinforced. If the engine is powerful and the board is made of ordinary plywood, it is advisable to install additional stainless steel or dural mounting plates under the mounting of the steering thrust and hydraulic cylinder (or cable bracket).
First, take the crank out, and set the steering thrust on the engine's lower unit. Then, fasten the drive mechanism on the trans board. For mechanics, this is the bracket that the cable passes through. It's important to ensure that the motor and the control cable are parallel, and the distortions will cause rapid wear and tear.
⚠️ Attention! When drilling a transom board, only use metal drills and sharpened wood. Do not allow laminate chips or damage to plywood layers, as this can disrupt the sealing and lead to rotting.
Laying the cable to the helm is the most important step. The cable should go without sharp clamps. In places where you pass through the side or console, use special sleeves or corrugated sleeves to protect the shell. After assembly, be sure to check the full steering from side to side. The motor should turn smoothly, without jerks.

Maintenance and care
Even the most reliable steering-stuff Every time you go into the salt water, you have to wash the system with fresh water, the salt is drying, it's crialized, it starts to corrode the metal and the seals, and you have to pay special attention to the exit points of the hydraulic cylinder rod or the end of the cable.
For mechanical cables, there is a special lubricant (usually lithium or Teflon) that must be applied to the moving parts and, if possible, inside the cable shell through special holes or removing the tips, and if the cable begins to walk tightly or with a crunch, it is better to replace it, since corrosion could begin to vegetate inside.
Hydraulic systems require fluid control and no leakage, and if you notice that the steering wheel is wobbly or the motor is no longer on course, you may have air or oil in the system, and you may need to pump the system according to the manufacturer's instructions.
Regular lubrication and freshwater flushing increase the life of the steering by 2-3 times. Don't ignore simple maintenance procedures after every fishing trip.
Frequently Asked Questions (FAQ)
Can I install the steering wheel on the boat without a transom board?
Theoretically, you can use special inflatable or rigid mounts that are fixed to cylinders or stringers, but these structures are less reliable and can be shifted under load. For full steering, a rigid transom board or transom is mandatory.
Do I need to remove the rudder when installing the steering wheel?
Yes, 99% of the time, the crane is completely dismantled because of the steering thrust, and there are rare adapter models that allow the crane to be left as an emergency control, but they are difficult to install and do not provide rigid fixation.
What length of cable to choose for a boat 3.6 meters?
For a boat 3.6 meters long with a console mounted on the second can, usually enough cable length of 3 meters (model 300 cm). If the console is planned on the nose or the boat is longer, it is better to take 4 meters. the length reserve is always easier to remove than to build.
Will the mechanical steering go to the 60 hp engine?
Technically powerful mechanical cables (heavy Duty series) can withstand both 60 and 70 hp, however, the force on the helm will be significant, especially at low speeds or when reversing.
