Owning an inflatable motorized boat opens up opportunities for fishing and resting on the water, but controlling a powerful outboard motor requires certain skills and physical strength. slab-stove This is where remote control (AR) comes in, allowing the operator to be anywhere in the cockpit, while maintaining full control of course and traction.
The modern market offers many solutions, from simple mechanical propulsion to complex electromechanical systems with hydraulic drive. outboardIt is important to understand that an incorrectly selected or mounted system can lead to a trans trans failure or, worse, loss of control of the boat on the move.
In this article, we will discuss all aspects of the selection and installation of AR, paying special attention to the specifics of inflatable boats. You will learn about the differences between cable and electric models, understand how to avoid the typical mistakes when laying cables and connecting electronics. Competent integration of this system will turn your boat into a comfortable and safe boat that can withstand any tests of the elements.
Types of Remote Control Systems: Mechanics vs. Electrics
The main separation of systems is based on the principle of transferring force from the pump to the engine. cable-controlThis system uses special cables in the shell (bowdens), which transmit the mechanical force of turning the rummel directly to the rotary mechanism of the motor, a time-tested technology that is highly reliable and maintainable in the field.
Mechanics, however, have limitations: With the length of the cable (more than 3-4 meters) or with steep curves, the force on the tiller can become excessive, which tires the operator. In addition, cables tend to stretch over time and require periodic adjustment. For powerful engines (50 hp and above) or for boats with a double tiller, often choose electromechanical.
⚠️ Note: The use of cable systems on motors over 90 hp on PVC boats is not recommended due to high inertia and the risk of transom breaks in a sharp turn.
Electrical systems (e.g., Hydraulic Steering Or electric drives, they don't have the problem of physical effort, the operator just gives a light signal, and the powerful actuator turns the motor. autopilot And navigation systems, because they have convenient connectivity interfaces, but they require a good on-board network and are more difficult to diagnose.
Criteria for selection for inflatable vessels
The choice of AR for PVC boats has its own specifics, different from the installation on boats with a rigid hull. The main feature is a soft transnec and limited cockpit space. The system should be as light as possible so as not to overload the stern, and have reliable protection against corrosion, since salt water and constant humidity are the main enemies of metal elements.
When choosing, consider the length of the cable. Inflatable boats of standard length of 3 meters (10 feet) is often not enough, especially if the hummulus is carried on the nose or installed in the center. In such cases, you need to order elongated sets or use adapters. Also important is the diameter of the cable: for motors up to 30 hp, a cross section will fit. 3300 mm (C2 type), and for more powerful units requires a reinforced version 3300 mm (Type C8).
The quality of the hummel material also plays a role: plastic elements can crack in the cold or burn out in the sun, so the models with aluminum base and rubberized handles should be preferred. trimming (control of the tilt of the lower unit) directly from the tiller - a huge plus, which significantly increases the comfort of management.
When ordering cables, always take a reserve of 30-50 cm more than the measurement with a roulette shows. Excess length can be carefully folded with a ring and fixed with clamps, but it will be extremely problematic to build a short cable in a reservoir.
Tools and preparation for installation
Remote control installation is a process that requires precision and a set of tools. Before starting work, make sure you have everything you need on hand. Incomplete training can leave the boat understaffed in the middle of the process, which is especially frustrating the day before you go to the pond.
You will need:
- 🔧 Set of wrenches and heads (for tightening the fastener of the translance and motor)
- 🔪 Sharp knife or construction cutters (to trim cables and remove insulation)
- 📏 Roulette and marker (for accurate marking of the gasket paths)
- 🔦 Lantern (to inspect hard-to-reach places in the cockpit)
- 🧴 Silicone lubricant (for processing cables and seals)
Pay special attention to the preparation of the workplace. The boat should be fully pumped and installed on a flat surface. If you work in the garage, ensure good lighting. All electrical connections in the onboard network before starting work must be de-energized by turning off the power supply. battery.
☑️ Preparation for the installation of DR
Step-by-step instructions for installing a cable DR
Installation begins with the removal of the tiller handle from the engine, usually with one or two bolts, and after removing the old handle, the DR drive mechanism is installed in place, which comes with the kit, and it is important to use all the pads and washers from the kit to ensure that it is tight and free of backlashes.
The next step is to lay the cables. This is the most important point. The cables should not have sharp inflections (bending radius at least 20 cm), otherwise the inner core will quickly be rubbed. On PVC boats, cables are often laid along the cylinder or under the floorboard. To protect against abrasion on the rough surface of the fabric or floor, use a corrugated tube or special plastic clips.
The ropes on the tiller require precision. After fixing, tension adjustment must be made. The tiller in neutral position must clearly correspond to the average position of the motor. If the motor is facing left or right with the handle centrally positioned, the cables are installed incorrectly or the tips need to be adjusted.
⚠️ Attention: It is strictly forbidden to lubricate the inner cables of DRs with thick lubricants (Litol, Solidol). In the cold, they will freeze, and in the summer they will collect sand, which will lead to a jamming of the system. Use only Teflon sprays or dry lubricants.
After mechanical assembly, check the system on land. Have the assistant turn the humming device while you watch the engine react. The course should be smooth, without jerking or extraneous sounds. Make sure that when the rummel is fully rotated, the motor turns to the stop, but does not try to turn further, creating excessive pressure on the mechanism.
The main criterion for successful installation is the absence of backlashes in the connections and smoothness of the cables throughout the entire range of movement from side to side.
Comparative table of system specifications
For ease of choice, let’s look at the main parameters of popular types of systems in a comparative table, which will help you quickly navigate the technical nuances and make an informed decision.
| Parameter | Mechanical (Tross) | Electromechanical | hydraulic |
|---|---|---|---|
| Max, engine power. | up to 115 hp | 250 hp. | up to 350+ hp |
| Effort at the tiller | Medium/High | Minimum | Minimum |
| Difficulty of installation | Low. | Medium | High. |
| Cost | Low. | Medium | High. |
As you can see from the table, for most owners of PVC boats with engines in the range of 9.9-40 hp, the best choice is a high-quality mechanical system. It is simple, cheap and reliable. However, if you are planning to upgrade to a powerful four-stroke or install complex electronics, you should consider switching to electric.
It's also worth noting that electrical systems consume energy, and if you're idling for long periods of time or if you're maneuvering frequently, you can see that energy consumption can be noticeable, especially if you have one small battery. backup Or switch to lithium batteries with higher capacity.
Maintenance and typical faults
Even the most reliable system requires maintenance. The main enemy of AR is salt corrosion and sand. After each release, especially in salt water, it is recommended to rinse the rummel and visible parts of the cables with fresh water. Periodically, once a season, remove the hummel casing and check the condition of the internal mechanisms.
One of the common problems is the untwisting of the cables, and over time, the cables can stretch slightly, and the backlash will become visible on the tiller. Most modern systems have the ability to tighten the cables with adjusting nuts at the ends, and if the cable starts to "crack" or get snatched, it must be replaced.
What to do if the DR cable is jammed in water?
If the cable is stuck in the turning position, do not try to force the rummel - this will lead to a cliff. Carefully reach the motor (with caution!) and try to manually turn the engine tiller or use the mooring end tied to the lower unit to level the course before coming ashore.
Also, monitor the electrical contacts if you have a system with electric drive or trimm buttons. Contact oxidation causes unstable operation or complete failure of the system. Use special sprays, contact cleaners and dielectric lubricant to protect the connections from moisture.
Safety and operating rules
Remote control does not exempt the operator from safety regulations. On the contrary, the presence of DR requires increased concentration, since the operator is farther from the engine and may not hear changes in its operation. escape-line (check) engine jamming, fixed on clothing or near the operator.
When maneuvering in crowded areas or near obstacles, don’t rely on DR alone. Have a plan of action in case of system failure, such as knowing how to quickly switch to manual control (if the engine design allows) or how to shut down the engine remotely.
Check the mounting bolts of the transom board regularly. Vibration from the motor and jerks when the ARs are working can weaken the connections. Using a thread locker (anaerobic sealant) when installing the system is a mandatory requirement to prevent spontaneous unscrewing of the screws.
Can I install the DR on my own or do I need a master?
Installation of mechanical AR on a motor up to 40 hp can be done independently, having basic skills with the tool and following the instructions. However, for complex electrical systems or powerful motors, it is better to consult specialists to maintain the engine warranty and be sure of safety.
Does the AR installation affect the engine guarantee?
By itself, installing a certified AR does not invalidate the warranty. However, if the engine elements are damaged during installation (threads are broken, wires are broken, the tightness of the lower unit is broken), the warranty case may not be recognized.
How often do I need to change the remote control cables?
The life of the cables depends on the intensity of operation and conditions. On average, quality cables last 5-7 years. However, if you notice jerks, creaks or increased force on the tiller that is not eliminated by lubrication, the cables are better replaced prophylactically.
Will DR be suitable for electric motors?
Yes, there are special systems for electric motors, but most often they use universal mechanical cables adapted to the attachment of electric traction, the main thing is to make sure that the rope travels according to the course of rotation of the electric motor leg.
Should I lubricate the DR cables?
Modern AR cables (especially in plastic coatings) often have an internal lubricant and do not require additional maintenance "inside"; you only need to lubricate the hinge joints from the outside. Trying to pour oil inside the cable can dissolve the factory lubricant and cause harm.
