Controlling an inflatable boat with a tiller thrust is a classic that is available to every angler. However, when you switch to more powerful engines or go on long walks, a simple control lever is no longer convenient. steeringIt's not just a matter of comfort, it's also a matter of safety, especially when driving at high speeds or in high wave conditions.
The current market offers many solutions, from simple cable systems to complex hydraulic drives. It's important to understand that the steering wheel system changes the ergonomics of the cockpit, and you'll need not only the steering mechanism, but also, most likely, the steering mechanism. console for installation of devices and bracket for the motor. It is critical to choose a system with a safety margin of at least 30% of your engine’s maximum thrust to avoid breaking the transom in sharp maneuvers.
In this article, we will take a look at what types of steering are available, what they are made of, and what to look for when buying, how to properly mount a system so that it does not creak or jam, and also learn the nuances of service for different types of drives. A competent approach to the selection of equipment will allow you to enjoy the control without being distracted by technical problems.
Advantages of installing steering on an inflatable boat
The transition from the rumble to the steering wheel is a tremendous comfort boost. The anglers who spend 6-8 hours on the water were the first to appreciate the ability to sit comfortably without straining their back and arm. But there are other, less obvious advantages. autopilot A more accurate GPS tracker that requires a constant connection to the steering machine.
In addition, steering allows you to move the control point to the center of the boat or closer to the nose, which improves weight distribution. This is especially true for boats with two passengers, where the weight of the motor on the transom can cause a different on the stern. When you move the control, you often get the opportunity to redistribute the weight of the batteries and fuel tanks.
⚠️ Attention: Installing the steering wheel increases the overall weight of the structure on the transom. Be sure to check the maximum load capacity of your transom and the length of the boat so as not to disturb the centering.
Another important aspect is safety: When hitting an obstacle or jerking sharply, the cable-driven steering wheel extinguishes some of the inertia transmitted to the operator's hands, as opposed to rigid thrust, which reduces the risk of injuries to the hands and elbow joints, and the presence of a steering wheel makes it easier to control the boat with one hand, leaving the second one free to work with a sonar or a navigator.
Types of steering mechanisms: cable and hydraulic systems
The main division of steering gear for small craft is by drive type. On PVC boats, where weight and dimensions matter, there are two main types most often found, and understanding their differences will help you make the right choice for your budget and tasks.
The first and most common type is cable-controlIt's a metal cable in a protective shell (Bowden) that connects the steering wheel to the rotary mechanism of the motor. These systems are divided into irrevocable (the cable moves only one way when the steering wheel rotates) and returnable (the cable moves back and forth). Rack and Pinion (or) rotary (or rotary)
The second is hydraulic drive, where the force is transmitted through the fluid in the hoses, which ensures smooth running, no backlashes, and the ability to install the steering wheel anywhere in the cockpit, even far from the engine. However, hydraulics are much more expensive, heavier and more difficult to install, so it is rarely used on boats up to 4 meters long.
- 🔹 Cable systems: Cheaper, lighter, easier to install, but can have backlashes over time.
- 🔹 Hydraulic systems: Perfect smoothness, no backlashes, high reliability, but high price and complexity.
- 🔹 Electrical actuators: Rare for PVC, they require a lot of energy, but provide unique integration opportunities.
Materials of manufacture and design features
The durability of steering is directly dependent on the materials used in its production: aggressive aqueous environment, salt, ultraviolet light and temperature changes require the use of special alloys and coatings. Cheap models often sin with the use of conventional steel cable without quality protection, which leads to rapid rusting.
Cords are most often made from ABS plastic with rubberized inserts or stainless steel. The good thing about plastic is that it doesn't heat up in the sun, it doesn't stick to your hands, it doesn't conduct electricity. Metal steering wheels look aesthetically pleasing, but require more care. The gearbox itself is usually covered with a plastic or metal casing.
The quality of the cable is a special consideration. stainless steel Teflon coated or multi-layered moisture protection, the end fittings of the cable must be reliably pressed, and cheap ones can be unfurled after the first season of active use, creating dangerous backlashes.

Criteria for the choice of steering wheels for PVC boats
Choosing the right model is a balance between cost, weight and functionality. For PVC boat owners, weight is critical. Installing a heavy steering column and a powerful motor may require increasing the diameter of the cylinders or using a stiffer floor to keep the boat running.
The length of the cable is the second important parameter: standard lengths are 3, 3.3, 4 and 5 meters. For boats 3.2-3.6 meters long, a cable 3 meters long is usually enough. console far in the nose or using two motors, the length should be calculated with a margin, avoiding sharp inflections.
For small power (up to 15 hp) is enough steering wheel diameter of 280-300 mm For more powerful engines (20-30 hp and above) it is better to take the steering wheel of a larger diameter (330-380 mm), as this gives a gain in the lever and facilitates control.
- 🎣 Compatibility: Make sure the steering machine fits your type of motor (only outboards with a tiller).
- 🎣 Package: The kit should have everything you need: cable, steering wheel, brackets, fasteners. Often the fasteners have to be purchased separately.
- 🎣 Guarantee: The presence of manufacturer service centers in your region.
☑️ Checklist before purchase
Instructions for installing steering yourself
You can do the steering DIY installation with a minimum set of tools, the key is to be consistent and take your time, and errors in the installation phase can lead to water jamming, which is unacceptable.
Start by mounting the motor bracket on the transom, which should be fastened as tightly as possible, preferably through a reinforced transom board, then install the steering machine itself on the bracket, make sure that the axes of rotation coincide and there are no distortions.
The rope is the most important step, the cable must go from gearbox to steering wheel in smooth arcs, the radius of the bend should not be less than the minimum permissible (usually 20-30 cm, specified in the instructions), sharp clamps will lead to rapid wear of the inner shell and snag of the cable.
⚠️ Attention: Never lubricate the cable drive with thick, consistent lubricants (Litol-24) inside the shell! This will cause the lubricant to freeze in winter and stuff dirt. Use only special cable sprays or dry graphite lubricants.
Once the cable is laid, connect it to the steering wheel and to the rotating mechanism of the motor. The tension of the cable should be uniform. Check the steering from stop to stop. It should be smooth, without jerks and creaks. If everything is in order, securely lock all the bolts and install protective casings.
Maintenance and care of the steering mechanism
Even the best steering wheel requires regular maintenance, and at the end of each season, before the boat is preserved, prevention is required, which will prolong the life of the mechanism and ensure safety in the next year.
First, check the cable for damage to the outer shell, if you see scuffs or tears, the cable needs to be replaced, then clear the exposed parts of the mechanism of salt and dirt, you can use fresh water and a soft brush.
The lubrication of the moving parts is done according to the manufacturer's instructions. Usually the joints of the motor and gearbox attachment are lubricated; the cable itself does not need to be lubricated inside the shell if it is of good quality and has an internal lubrication. If you feel that the stroke has become tight, it is better to replace the cable whole than to try to revive it with oil.
Keep the boat with the rudder installed is better in disassembled form or with the helm removed to exclude accidental impacts. The mechanism on the transom should be covered with a protective cover from dust and moisture.
Frequently Asked Questions (FAQ)
Can I install the steering wheel on a boat less than 3 meters long?
Technically, it is possible, but it is rarely justified: On boats 2.7-2.9 meters long, the installation of the steering wheel, console and bracket will add 15-20 kg of weight, which will significantly reduce speed and payload.
Do I need to change the sleeve when installing the steering wheel?
In most cases, yes, a regular plywood board may not be able to withstand the weight of the bracket and the additional torsional loads, and it is recommended to install a reinforced transom of marine aluminum or thick moisture-resistant plywood coated.
Are the wheels of different manufacturers compatible with any motors?
Most modern steering systems are versatile and fit with Yamaha, Mercury, Tohatsu, Honda and their Chinese counterparts. However, the mounts may differ. Always check the compatibility table or the availability of adapters in the kit.
How often should the steering cable be changed?
The lifespan of a quality cable is 5-7 years with moderate operation, and if you use the boat in an aggressive environment or intensively, you should replace it every 3-4 years, even if there is no visible damage.
