Control boat with a rummel is a classic available to everyone, but with the growth of engine power and the desire to increase comfort on the water, many owners are thinking about installing a full-fledged steering wheel. Steering kit turns the vessel from physical activity into a light movement of the wrist, which is especially important for long transitions or fishing on a strong current.
Choosing the right mechanism is not just a purchase of hardware, but a comprehensive solution that affects the safety and maneuverability of the vessel. The cable systems They are the standard for inflatable vessels due to their flexibility and ease of installation, but the market offers many options for execution, where it is easy to confuse a beginner.
In this article, we will discuss in detail what a high-quality kit consists of, how to choose the length of the cable under your boat and what nuances to pay attention to when assembling to avoid problems at the most inopportune moment.
Design and key components of the system
Any modern remote control system (RC) for PVC boats is based on three main elements: a steering mechanism (reductor), a cable and a steering wheel. The gearbox is attached to a transom and converts the rotation of the steering wheel into the forward movement of the cable, which in turn pushes or pulls the engine's tiller, turning a lower unit. Effort at the tiller It is evenly distributed, allowing you to control even powerful motors with one hand.
The most important element is the cable itself, and inside the flexible shell is a Teflon-coated steel cable or a multi-layer synthetic thread that allows smooth running. The length of the cable for PVC boats usually varies from 2.7 to 3.3 meters.The use of a shorter or excessively long cable, unnecessarily, can lead to system malfunction or stacking difficulties.
The steering wheel is not only a control, but also an important part of the aesthetics of the cockpit, it can be plastic, chrome or wooden rim, the main requirement is a reliable attachment to the gearbox shaft and conform to the landing size, which is often standard.
⚠️ Warning: When buying a kit, make sure the cable stroke (usually 200-210 mm) meets the requirements of your engine. Some powerful motors require increased stroke to turn at a full angle.
Manufacturer's choice and technical specifications
The market is flooded with offers from Chinese manufacturers and well-known brands, and the leader in this segment is traditionally considered to be the company. Teleflex (SSS and SR series), whose products are highly reliable and durable, although they are more expensive than their counterparts. SeaStar or various OEM kits, often copy the design, but may use less quality materials for the internal stuffing of the cable.
When choosing, you should pay attention to the type of compaction of the gearbox. For PVC boats, protection from moisture is critical, since the mechanism often finds itself in the area of splashes or direct contact with water when turbulent. Salic seals high quality prevent water from entering the gears, excluding corrosion and jamming.
Compare the main parameters of popular solutions:
| Parameter | Budget segment | Premium segment | Impact on operation |
|---|---|---|---|
| Material gears | Plastic/Zinc alloy | Stainless steel/Brass | Resource and smoothness |
| Type of cable | Unlubricated steel | Teflon Steel/Synthetics | Strength on the wheel in winter |
| Protection (IP) | Basic | Complete sealing | Life in salt water |
| Completement | Often without fasteners | Full set of bolts | Difficulty of installation |
You don't have to be as cheap as possible, because failure to steer at speed or when you storm a wave can be very expensive, and a high-quality mechanism will last for decades with minimal care.
Preparation for installation and necessary tool
Installation of the steering kit is a process that requires careful and pre-preparedness. Before starting work, you need to dismantle the regular tiller (if it interferes) and free up space on the transom. You need a set of wrenches, a drill with metal drills, a silicone sealant and possibly a file.
The first step is always to mark up. Apply the gearbox to the transom at the intended installation site and check if it blocks access to the drain hole or the boat's carrying handles. Centrification The mechanism of the boat’s diametric plane is critical for symmetrical control.
☑️ Preparation for steering wheel installation
It is also important to check the condition of the transmolant itself. If it is made of plywood, make sure that there is no rot or stratification at the attachment site. If necessary, install additional stainless steel reinforcement plates or aluminum on the inside of the transmolator to distribute the load from the snatch of the cable.
Step-by-step installation instructions
The installation process can be divided into several logical steps: first, you attach the gearbox itself, drill the holes through the markup, treat their edges with anticort, and apply a layer of sealant around the holes before screwing the bolts in, and this will prevent moisture from entering the layered material of the transom.
The most important step is the cable laying, and the cable is placed on the sides of the boat, preferably in a protective plastic casing or corrugated, to prevent rubbing on sharp corners or friction on cylinders. Minimum radius of bending The cable should not be less than 30 cm, otherwise the internal structure may be damaged, leading to jamming.
⚠️ Warning: Never bend the cable at a sharp angle or twist it when mounted, which will irreversibly damage the internal structure and lead to rudder jerks.
The connection to the engine is through a special bracket, which comes complete or is made independently, the bracket is put on the motor's humming wheel and is fixed by the bolt, it is important to ensure the free movement of the cable without tension in the neutral position.
The final step is to install the steering wheel and check the system, and the wheel is put on the shaft and fixed by a nut, and then you need to shift the steering wheel from side to side several times, making sure that the ride is smooth and there are no jamming.
Tension adjustment and adjustment
The right tuning of the cable tension is the key to comfortable control. The cable should not be pulled like a string, but it should not sag. In the neutral position (routine course), the backlash on the steering wheel should be minimal, but the engine rump should freely return to the center when the steering wheel is released (thanks to the own weight of the lower unit or spring mechanism, if any).
Adjustment is done by using threaded tips at the ends of the cable, and by rotating them, you can lengthen or shorten the effective length of the cable. Symmetry - key parameter: the number of turns of the steering wheel from the center to the left should be equal to the number of turns to the right.
If you notice that the steering wheel is tight or, conversely, there is a big backlash, do not ignore this. In the first case, check the path of the cable for pinches, in the second case, tighten the adjustment nuts, and it should become a habit to check these parameters regularly before each outlet.
Maintenance and typical faults
Even the most reliable steering kit requires attention. The main enemy of mechanics is water and sand. After every trip, especially on salt water or in muddy conditions, it is recommended to wash the mechanism with fresh water. Periodically, once a season, it is worth taking off the cable and lubricating it with specialized compounds.
Typical problems faced by owners:
- 🛑 Bite the cable: most often occurs due to a violation of the geometry of the gasket or the ingress of dirt inside the shell.
- 🛑 Luft steering wheel: indicates wear gears gear gear gear gear gear gear or the need to adjust the tension.
- 🛑 Corrosion of anchorages: Using conventional steel bolts instead of stainless steel leads to rapid rusting.
If the cable starts to crunch or the movement becomes intermittent, it is better to replace it whole than to try to revive the old one, the cost of the cable is incommensurable with the risk of losing control on the water.
Can I install steering on a boat less than 3 meters long?
Technically possible, but the feasibility is questionable: on small boats (2.4-2.9 m), the rudder can unnecessarily weight the transom and take up useful space.
What to do if the cable freezes in winter?
If moisture builds up inside the cable, it can freeze. Don't put too much effort into not breaking the shell. Put the boat warm or use a lock defroster (spray) by pouring it into the end of the cable.
Are the cables compatible with different manufacturers?
Most cables have standard threading at the ends, but the length and pitch of the thread may vary, it is better to buy a kit (reducter + cable) from one manufacturer or strictly follow compatibility tables.
Installing steering is a significant step in upgrading your PVC boat, raising the comfort class to the level of boats. The right choice of components and high-quality installation will ensure you years of safe and enjoyable operation.
