Water transport management requires not only experience and composure from the captain, but also reliable communication with the power plant. Boat distance It is the critical node that allows the operator to control engine speed and direction from a safe and convenient location, and without a proper reverse mechanism and gas, safe maneuvering in locks, mooring or trolling becomes almost impossible.
Modern control systems have evolved from primitive levers attached directly to the tiller to complex electronic units with the ability to install multiple control posts. Mechanical distance On cables, it remains the standard for most small and medium-sized vessels, balancing cost, maintainability and simplicity, and understanding how it works will help avoid costly breakdowns at the most inopportune time.
In this article, we will analyze Construction of the unit in detail, consider the nuances of installation and discuss the typical mistakes that boat owners make when self-assembling. It is critically important to know that the length of the cable distance should not be less than the minimum bend radius specified by the manufacturer, otherwise the cable may break inside the braid. Competent approach to the choice of equipment will prolong the life of your motor and provide comfort on the water.
The principle of operation and the mechanism of reverse gas
The main task of the remote control system is to transfer mechanical force from the driver's lever to the carburetor (or throttle of the injector) and the engine gearshift mechanism. distance-drive It's a housing that has cable guides and a lever system inside it, and when you move the handle forward, you pick a backlash, and then you turn on the gear, and then you go ahead and you increase the engine speed.
The key here is the mechanism of blocking the gas before the gear is turned on, which prevents the boat from jerking abruptly at launch, which is especially important for light inflatable boats and flat-bottomed boats. Yamaha or Mercury, a system of smooth opening of the throttle is used, eliminating thrust dips.
Why is the backlash in the system important?
The backlash is the free stroke of the lever at the beginning of the movement, and it is needed for the gear to start (friction) first, and only then the throttle valves begin to open, and if the backlash is not available or it is too small, the motor can growl in the neutral or stall when the gear is turned on.
It's worth noting that the reliability of the entire system depends on the quality of the cables and their proper gasket, and the cable consists of a steel core that moves inside a Teflon or plastic shirt. Friction between these elements should be minimal, but the system should remain sufficiently rigid to clearly transfer force.
Types of Control Systems: Mechanics vs. Electronics
Two main types of actuators dominate the water-motor market: Mechanical systems that run on cable traction are the most common because of their versatility and ability to be installed on motors of various power, and they are divided into Rotary (rotary) and Rack (ricket). Rack distance It is considered to be smoother and more durable, as it uses a geared rack rather than a cable as the main transmitting element inside the control unit itself.
Drive-by-Wire is gaining popularity, especially in the high-power outboard motor segment, where there is no physical link between the lever and the motor, the signal is transmitted over wires, allowing control posts to be installed anywhere in the cockpit, two or three-post systems without complex mechanical switches, and integrating control with onboard computers.
However, for most owners of PVC boats or small aluminum boats, mechanics are the only option: they do not require electricity to operate (except for position sensors), are cheaper to repair and are easier to maintain. When choosing between types of systems, it is important to consider engine power: for engines over 115 hp, systems with power steering and electronic throttle control are often already recommended.
When switching from a remote control to a desk control, there is often a question of compatibility. Most modern motors have a universal mount, but you may need to change the switching lever on the motor itself to the back end for the cable, which is a standard procedure that takes no more than 15 minutes.
Rules for selection and laying of cables
Choosing the right length of the cable is not a matter of aesthetics, but a requirement of safety and durability. Too short a cable will create tension that will cause spontaneous changes in speeds or make it difficult to turn on the gear. Too long a cable is harder to fit without the formation of loops and sharp corners, which is also unacceptable.
There is a golden rule of gasket: the radius of bending of the cable should not be less than the minimum permissible value, usually 20–25 centimeters (depending on the model, for example, the radius of the curve should not be less than the minimum permissible value, usually 20–25 centimeters). Cable C4 or C8Sharp inflections at a sharp angle destroy the inner structure of the cable, causing it to jam, the cable should follow the most straight line from the machine to the motor, bending the obstacles in smooth arcs.
The attachment uses special clamps and clips that fix the braiding of the cable, leaving the inner core movable. It is important not to drag the locking bolts at the ends of the cable, so as not to deform the thread or the tip itself.
Use silicone lubricant to treat the cable braid before you stretch through the complex areas of the case, which will significantly reduce friction and facilitate installation.
The table below gives recommendations for choosing the length of the cable depending on the distance to the motor:
| Distance to transmuter (m) | Recommended length of cable (foot) | Recommended length (metres) | Motor type |
|---|---|---|---|
| 3.5 m | 11 ft (B11) | 3.35 m | Low power. |
| 3.5 - 4.5 m | 13 ft (B13) | 3.96 m | Average power |
| 4.5 - 5.5 m | 15 ft (B15) | 4.57 m | Medium/High. |
| 5.5 - 6.5 m | 17 ft (B17) | 5.18 m | High power. |
Step-by-step instructions for setting the distance
Installation of the control system requires accuracy and consistency of actions. Before starting work, make sure that the battery is disconnected and the motor is securely fixed. First, the control unit (machine) itself is installed on board or the dashboard. To do this, you need to cut a hole of the appropriate size using the template that comes with the kit.
Once the hull is fixed, the cables are laid, and it is important to ensure that the cables pass through the side, using special sealants or sealants to prevent water from entering the hold, and the motor is connected through the response slats that are attached to the engine bracket.
☑️ Checklist before first launch
Adjustment is the most important step. You need to adjust the length of the cables so that the position of the lever "Neutral / Idle" on the motor also has neutral and minimum revs.
⚠️ Warning: After installation, be sure to check the system on land, make sure that when the lever is fully under way, the motor does not go into a mode that exceeds the maximum permitted speed without loading, and that the reverse mechanism switches clearly, without delay.
Typical malfunctions and methods of their elimination
During operation, the water motor can face a number of problems related to wear and tear or improper setting. tight-tight This can be caused by dirt and sand getting into the braiding of the cable, corrosion of the moving parts of the machine or too tightening of the adjustment nuts.
Another common problem is that you can't get full speed, and often the reason is that the gas cable is too long or short, and the lever on the engine just doesn't stop, and it's worth checking the state of the candle and the fuel system before you sin on the control mechanics.
If the lever is hanging and does not lock position, you need to check the wear of the friction washers inside the control unit. In rack systems, wear can affect the gear teeth, in such cases, you need to replace worn-out elements or the entire assembly.
Regular lubrication and washing of cables with fresh water after each release into salt water is the main secret of long-term service of a remote system.
And it happens that the motor will stop when you try to turn on the gear, which is a sure sign of an incorrectly adjusted mechanism for locking the gas or a malsynchronization between the gas cable and the gearshift cable, and you need to re-adjust the manufacturer's manual.
Management and seasonal maintenance
After each use, especially in salt water, the outer parts of the machine and the exit of the cables should be rinsed with fresh water. Periodically, at least once a season, it is recommended to remove the cables and lubricate them with specialized compounds that displace moisture.
Visually inspecting the cable braid for cracks, clamps and corrosion should become a habit. If you notice the inner cable starting to "fluff" or rust at the exit of the braid, it should be replaced immediately. A full-blown cable break is an emergency that can lead to a collision or loss of control.
When you can preserve the boat for the winter, it is better to remove the cables or, if this is not possible, treat them with conservation lubricant and leave them in a relaxed state (lever in neutral), which will prevent the metal fatigue and loss of elasticity of the braid in the cold.
Can I repair the cables on my own?
Replacing the inner core is possible, but requires a special tool for pressing the tips, cheaper and more reliable to buy a new cable assembled, since the factory pressing ensures strength, which is difficult to achieve in garage conditions.
Compliance with these simple rules will allow you to boat-distance You can be a long-term, confident operator in all environments, so don't skimp on the quality of your components, because that's what makes your navigation safe.
Frequently Asked Questions (FAQ)
How do I determine the length of my boat?
Measure the distance from the control lever to the transom in a straight line, add the reserve to the gasket (usually 1-2 meters) and round to the nearest standard size (11, 13, 15, 17, 19, 21, 22, 24, 26, 28, 30, 32, 33 feet).
Why did the distance lever start to run so tight?
The main reasons are: moisture freezes inside the braid (in winter), sand ingress, cable corrosion or lack of lubrication. It is also possible that the cable is laid with a bend radius less than permissible. Try to remove the cable, wash it and lubricate it, if it does not help, replace it.
Can you set the electronic distance to an old motor?
Older motors without electronic throttle control (carburetor) to install a full-fledged electronic system (DBW) is almost impossible without a major overhaul of the intake system, for them are only mechanical cable or rack systems.
What to do if the back door is missing?
Check the gearshift cable adjustments. You may have lost the settings or the cable stretched. If the adjustments don't work, the problem may be the frictions of the motor itself (wear and tear on the clutch discs), which requires repair of the gearbox.
Do I need to lubricate the distance cables?
Yes, periodic lubrication is necessary. Use special sprays for cables or lithium lubricants that are not washed away by water or frozen, which reduces friction and protects the steel core from corrosion.
