The transition from the control to the remote control is not just a matter of comfort, but a major step towards improving the safety and ergonomics of the boat. Installing a remote control system (DU) allows the operator to freely move around the cockpit, control the situation around and more conveniently place passengers or fishing equipment. power-driven and comply with electrical safety regulations.
Many aqueous motorists have difficulty selecting components, not knowing how different the cables from different manufacturers or how to calculate the required length correctly. reverse-reducerIn this article, we'll look at everything from the choice of the cranking site to the fine tuning of the gas thrust and reverse.
It is important to understand that boat-distance It is a complete solution that includes a mechanical part (cords, reverse gear) and an electric part (ignition lock, dashboard, wire harnesses). outboard We're going to look at proven installation techniques that can help you avoid common mistakes and get a reliable control system.
Selection of remote control system components
The first and most important step is to get the right gears. The market offers a lot of options, but the key parameters are reliability and compatibility with your motor. The main element is the cranking machine, which hides the gearshift mechanism and the throttle valve, and it is the quality of the execution of this unit that determines the smoothness of the lever and the accuracy of the control.
The second critical component is the control cables, which come in a variety of lengths and designs, standard lengths vary from 3 meters (10 feet) to 6 meters (20 feet) or more. Length choices not only need to take into account the distance from the transom to the ramp, but also the margin for laying on the sides with an obstacle detour. Using too short a cable will make it impossible to turn the motor to the maximum angle, and excess length will lead to the formation of loops and friction losses.
You should also pay attention to the type of connection of the electric part. Most modern motors use standard connectors, but older models or motors of certain brands may require adapters or individual soldering of contacts. Ignition lock The tiller must match the electrical circuitry of your motor, especially if there is an emergency stop system for the engine.
- 🔧 tiller-machine: the main control element, selected for the type of motor (2 or 3 cable system).
- 🔧 Control cables: must be in a Teflon braid to reduce friction and protect against corrosion.
- 🔧 Burning wires.: is necessary to connect the dashboard and ignition lock to the onboard network.
- 🔧 Fastening elements: bolts, nuts and stainless steel washers for installation on fiberglass or aluminum.
⚠️ Attention: Never use car-based control cables as a replacement for sea cables, which lack the necessary protection from salt water and can become sour after the first season, making it impossible to shift gears on the water.
Definition of installation site and preparation of cockpit
Planning the placement of a console or a rumble machine is a process that requires consideration of the ergonomics and design features of the craft. The location should be chosen so that the operator has a good view towards the stern and on the sides, as well as free access to control in any situation.
When marking the openings under the anchor, you must take into account the course of the control lever. It should not rest on the side of the boat, seats or other interior elements when moving from the "full forward" position to the "full backward" position. It is also important to provide space under the deck or behind the bulkhead for laying the cables without sharp curves that can damage the internal structure of the cable.
If the boat is made of fiberglass, when drilling holes, be sure to use a composite drill to avoid chipping and stratification of the gelcoat. For aluminum boats, it is critical to treat the edges of the holes with anti-corrosion composition and use a sealant when installing the fasteners. Hermetization The entry points of cables and wires into the cockpit are a mandatory requirement to prevent water from entering the housing.
Special attention should be paid to laying the track of the cables. They should go as straight as possible, with minimal number of turns. The radius of bending of the cable should not be less than the minimum permissible specified by the manufacturer (usually at least 15-20 cm).
- 📏 Markings: Apply the exact dimensions on the template before drilling the main material.
- 📏 Lever strokeCheck the amplitude of the movement of the handle in the assembled form until the final fixation.
- 📏 Tracing: pave the path of the cables so that they do not touch sharp edges and hot elements.
- 📏 Availability: make sure that the places of attachment of cables on the motor will be convenient to climb up for adjustment.
Use flexible wire or a special probe to pull cables through narrow channels and bulkheads. Tie the cable to the wire with tape so that it does not catch on to the interior of the boat.
Mechanical installation of reverse gearbox and cables
Installation of a gearshifter on the motor is the most critical step in mechanical assembly. This assembly converts the linear motion of the cable into the rotation of the gear lever and the throttle on the motor. Installation begins with the dismantling of the standard tiller (if any) and the installation of a transition plate or directly gearbox on the engine's lower unit.
The fastening must be done with high-strength bolts, necessarily using grover washers or a thread lock, because the vibration of the outboard motor can weaken any connection. Once the gearbox body is fixed, the cables are connected. The gas cable is usually connected to the throttle sector, and the reverse cable is connected to the gear lever.
Adjusting the length of the outer shell and the inner core of the cable is key. At the ends of the cables there are threaded tips that allow you to accurately set the length. When the handler is positioned "neutral", the levers on the motor must also be in a strictly neutral position. Luft is not allowed, but the tension must be free, so as not to create resistance.
To check the correct installation, you need to switch gears and gas several times, watching the operation of the mechanisms. The lever on the motor must go to the end in the positions "full gas" and "full reverse" in synchrony with the movement of the handle into the cockpit. If the stroke is limited, you need to adjust the length of the cable or the position of the mounting tips.
☑️ Mechanical installation
⚠️ Attention: Before the first start of the engine, be sure to check whether the throttle opens to the end. If the gas cable is too short, you will not be able to develop full power, and if it is too long, the valve may not close completely on idles, which will lead to unstable operation of the engine.
Connection scheme of the electric part of the distance
The electrical component of remote control includes the ignition lock, the dashboard (tachometer, temperature indicator, voltmeter) and the emergency stop system (kill switch). The connection scheme may vary depending on the manufacturer of the motor, but the basic principles remain unchanged.
A standard ignition lock for outboard motors typically has 4 to 6 pins, the main ones being: "B" (Battery) for battery power, "M" (Magneto) for engine stop mass, "S" (Starter) for starter start, "A" or "I" (Ignition) for onboard network and appliances. Misjection of contacts "M" and "B" can lead to short circuit and failure of the ignition system or switch.
To connect the dashboard, you need to know the wiring of the sensors on your motor. The tachometer connects to the "W" output (on Japanese motors) or the special output of the generator. The oil temperature and pressure sensor requires separate power and signal wire. All connections must be made using high-quality insulation, thermal shrinkage and, preferably, covered with conservation lubricant to protect against oxidation.
It is important to use wires with a cross section corresponding to the current load. 1.0-1.5 mm2 is enough for control circuits, but for starter power chains and main consumers, the cross section should be at least 4-6 mm2. It is better to lay the wires in a corrugated tube, fixing them with clamps to prevent rubbing against moving parts or sharp edges.
| Lock contact | Function | Color of wire (standard) | Where to plug in |
|---|---|---|---|
| B (Battery) | Power +12V | Red. | Plus battery (via fuse) |
| M (Magneto) | Stop the engine | Black and yellow. | Motor mass (through the stop button) |
| S (Starter) | Starter | Yellow | Starter retracting relay |
| I (Ignition) | Ignition/Devices | blue or white | Onboard network, tachometer, light |
Features of connecting Japanese engines (Tohatsu, Nissan)
Tohatsu and Nissan engines often use a separate tachometer wire (grey or gray with a strip) that connects to the generator's output under the flywheel or to a special connector. Incorrect connection of the tachometer can cause it to burn, since on some models the signal goes directly from the ignition coil without conversion. Always check the manual of a particular model before inserting into the electrician.
Setup, adjustment and first start
Once you've finished, you've got a fine-tuning phase, and even perfectly fitted cables can require adjustments after the first minutes of operation. The main challenge is to keep the lever in the cockpit synchronized with the actuators on the motor. Start by checking the neutral position: when you move the tiller lever to the center, the motor must be clearly neutralized, and the engine must start only in this position (thanks to the neutral starter).
Then you check the full stroke of the gas lever. When you move the handle forward, the carburetor valve should only open completely at the very end of the lever stroke. If you open it earlier, the motor will not give you full power. If you later can't use the entire throttle life, you can adjust it by twisting or twisting the tip of the gas cable.
The reverse is also adjusted. The gear lever is short, so the accuracy of the reverse cable is critical. The switching should be done with a characteristic click, but without undue effort. If the lever is tight, check the cable for inflections or lubricate the gearbox mechanism.
First start on the shore or with the engine raised (in the barrel), making sure the cooling water supply. Check the starter, the stability of idling and the engine response to the addition of gas. Examine all connections of cables and wires after the engine operation in different modes - vibration could weaken the fastener.
- ⚙️ Neutral starterMake sure the starter is only spinning in a neutral position.
- ⚙️ Full gas.: Check that the valve opens 100% at the end of the lever stroke.
- ⚙️ Idle move: Make sure the valve closes completely when the lever is returned.
- ⚙️ Stop buttonCheck if the engine is dead when pulling the emergency stop cable.
⚠️ Attention: If the control lever moves too tight after setting up, don't put too much effort into it. It can cause the cable to break or the plastic parts of the gearbox to break, and find the reason for the resistance -- most likely, the cable is laid with a small bend radius or the fastener will be pulled.
The quality of the distance is the balance between the clarity of the switch and the ease of travel. Do not allow backlashes, but do not pull the ropes with a string, otherwise the mechanism will quickly fail.
Frequent installation errors and their consequences
One of the most common mistakes is ignoring the protection of the cables from sharp edges. The vibrating of the boat causes the cables to walk millimeter by millimeter, and over time they rub the insulation and the steel vein against the sharp edges of bulkheads or fastening holes, which can lead to a sudden break of the cable gas or reverse at the most inopportune moment.
Another common mistake is incorrect sealing of the inlets. Water that gets inside the boat through the cable holes can accumulate in the hold, increasing weight and reducing stability. In the case of aluminum boats, the contact of the electrolyte (water) with heterogeneous metals (aluminium of the hull and steel of the cable) causes accelerated electrochemical corrosion.
Also, many people neglect to install fuses in the power chains. Short circuits in the wiring leading to the ignition lock can cause fire or failure of the expensive electronic control unit (ECU) of the motor. Use of insufficient cross-section wires leads to a voltage drop and unstable operation of the starter and instruments.
Ergonomics: If you place the rummel too far or too close to the seat, you'll be tedious to operate, the operator's hands should be free to sit on the lever, and the angle in the elbow should be comfortable to keep the boat in control for a long time.
How often should you lubricate the distance cables?
Control cables, especially if they are not in a sealed shell, are recommended to be lubricated with a special lubricant for cables (usually Teflon or graphite) at the beginning of each season and after each wintering. If the cables begin to walk tightly, grease should be carried out immediately. For cables in the Teflon shell, it is enough to lubricate only the hinges at the ends.
Can I extend the standard distance cable?
It's not recommended to build up the welding or twisting control cables, it breaks the integrity of the cable structure, creates stress points, and dramatically reduces reliability. If you don't have the standard length, you need to buy the right length of the cable. The maximum length for mechanical systems is usually not more than 6-7 meters, then problems with accuracy and force begin.
Why does the tachometer not work after setting the distance?
The most common problem is that the tachometer signal wire is not properly connected or the instrument itself is not configured. Some tachometers have a cylinder number switch (4, 6, 8) or motor type (2t/4t) on the back, and check if the tachometer wire is connected to the correct motor output (usually marked as "Tach" or has a color tag).
What if the reverse lever is not fixed in position?
The reverse cable must be unadjusted, and the counternut at the tip of the cable must be loosened and twisted so that when the handler moves to the forward or reverse position, the engine can reach the characteristic snap of the lock, and if there is no click, the motor can spontaneously move into the neutral under load.
Do I need to change the cables along with the rompell machine?
Yes, when replacing the roumpel machine, it is strongly recommended to change the cables, old cables can have hidden defects, stretching or corrosion, which will negate the benefits of the new control mechanism, and new cables will provide smooth running, which is often lost by old products.
