Operating a heavy boat on an inflatable or metal boat is always a physical exercise, and lifting an engine weighing 30-50 kilograms per transom is a challenge, especially given the need for precise positioning to attach the rods. power-lift It is becoming not just a convenient option, but a necessity for many owners of water equipment, who appreciate the health of the back and comfort.
Modern electric winches allow one person to easily cope with tasks that used to require the help of a partner, and the way they work is by converting the battery's electrical energy into mechanical force transmitted through a cable or chain, which radically changes the way we prepare for going to water, making the process less time-consuming and safer.
In this article, we will discuss in detail the technical nuances of the selection of the lifting mechanism, the features of installation of various types of structures and the rules of their maintenance. A competent approach to this issue will avoid overloading on the transom and prolong the life of your equipment. Below are the key aspects that you should pay attention to before buying.
The principle of operation and the main advantages of electric winches
The basis of any electric winch is a powerful electric motor that drives the gearbox. The gearbox, in turn, spins the drum or the star, winding the cable or the chain. loading capacityStandard models for outboard motors are usually designed for traction forces from 100 to 300 kilograms, which allows you to lift even heavy four-stroke units.
The electric drive has some advantages over manual mechanics: first, it's speed: it takes seconds to lift the motor; second, it's process control: you can stop the engine at any time to lock the motor in the right position. Many modern models are equipped with the right kind of powertrain. remote-controlThis allows the operator to be at the optimal viewpoint.
In addition, electrical systems often have built-in load limiters to prevent the mechanism from breaking when jammed or overweight, making them more reliable in the long run compared to cheap handheld counterparts, where human factor plays a crucial role.
- ⚓ Significant reduction of physical load on the operator when installing the motor on the transom.
- ⚡ The ability to control the lifting process with one hand or using the remote control.
- 🔒 Automatic braking systems for fixing the load at height.
- 🛡️ Protection of the mechanism from overloads thanks to built-in fuses.
⚠️ Warning: When choosing a winch, always consider not only the dry weight of the engine, but also the weight of additional components such as the propeller, lower unit and fuel tank, if they are lifted along with the engine.
Selection criteria: power, type of power and design
Choosing the right one power-lift The first and foremost parameter is maximum load, and engineers recommend that you choose a device with a power reserve of at least 30-40% of the weight of the lifted load, which will ensure that the engine runs in a gentle mode and prolong the battery life.
The second important aspect is the type of power. Most boat winches run on a 12-volt network, which is convenient because it allows you to use the main battery of the boat or an additional traction battery. However, there are also self-powered models that have built-in batteries, which makes it easier to install, but increases the overall weight of the structure.
The design of the lifting mechanism also varies. There are cable-driven models that are compact and lightweight, but require regular grease of the cable. Chain winches are more durable and not afraid of overlapping, but they are heavier and may require more space to accommodate the chain. stainless steel or aluminum with anticorrosion coating is preferable for use in salt water.
To understand the ratio of specifications, consider a comparative table of popular types of drives:
| Parameter | The cable winch | Chain winch | Hydraulic actuator |
|---|---|---|---|
| Weight of the machine | Low. | Medium. | Highly |
| Speed of ascent | High. | Medium | Very high. |
| Water resistance | Requires care. | High. | Maximum |
| Cost | Budgetary | Medium | High. |
Types of fasteners and methods of installation on the boat
Installation lifter There are several basic installation methods, each with its own specifications, the most common option is to attach directly to the transom of the boat using brackets, which requires drilling holes in the transom, which is not always acceptable for owners of PVC boats, but is ideal for metal and fiberglass cases.
Inflatable boats and catamarans often use removable structures that are attached to already installed transom boards or banks. Such systems do not require violation of the integrity of the cylinders and can be easily dismantled during transportation. It is important to ensure that the winch mounting point was strictly above the center of gravity of the motor or had a balancing system.
Installation must be used marine fittings The bolts and nuts must be of AISI 316 stainless steel, and all joints must be securely lawn, vibration during operation of the motor and dynamic loads during lifting can weaken the fastener if it is made poorly.
☑️ Checklist for installation
If you install a winch on a PVC boat, be sure to use wide pressing plates on the inside of the transom, which will distribute the point load from the bolts over a large area of the material, preventing it from rupturing or deforming.
⚠️ Attention: It is strictly forbidden to attach the electric lift only to the inflatable cylinder or soft structural elements without a rigid power frame.
Instructions for installation: step-by-step algorithm of actions
The installation process begins with marking. You need to determine the optimal height of the winch attachment, so that when raised, the engine does not interfere with the view and does not touch the elements of the cockpit, but it is reliably fixed. After marking the holes, they are drilled. For metal boats, the edges of the holes are necessarily treated with corrosion-resistant composition.
The next step is to install fasteners. Bolts are passed through the holes, reinforcers werehers and nuts are installed on the inside. Between the winch body and the transom, it is recommended to lay a layer of vibration insulation material that will also serve as a sealant. After tightening the bolts, you need to check the rigidity of the structure, applying a force exceeding the working weight.
The final step is to connect the electrical part, and the wires from the winch are brought to the battery through an automatic fuse, which should be located in close proximity to the battery. The wire section is selected according to the current consumed by the engine to avoid voltage drop and overheating.
Recommended cable cross section for current 50A: at least 10 mm2 (AWG 7)After mechanical assembly and electrical connection, a test run is performed without load, and then with the load, and you need to make sure that the running is smooth, there is no extraneous noise and the end switches work correctly, if they are provided by the design.
The nuances of sealing
To seal the holes in the transom, use a polyurethane sealant (like Sikaflex) that is not only applied to the washer, but also to the bolt thread before twisting, which will create a monolithic bond that will protect against water penetration even when in the water for a long time.
Operation, maintenance and security measures
Durability electric-lift After each release, especially in salt water, the mechanism must be rinsed with fresh water, and the salt deposits can quickly disable the moving parts of the gearbox and the electrical contacts.
Check the condition of the cable or chain regularly, there should be no rags, inflections or corrosion on the cable, the chain needs periodic lubrication with specialized formulations that are resistant to water washing, and pay attention to the condition of the electrical connectors: they should be tightly closed with protective caps.
Safety comes first. Never under a hanging load. Make sure there are no people around before you start lifting, and the motor path is free from obstacles. When lifting heavy motors, it is recommended to use a safety crease, which will prevent the engine from falling in the event of a major cable break.
- 🧼 Wash the mechanism with fresh water after each operation in salt water.
- 🔋 Watch the level of battery charge, do not allow a deep discharge.
- 🔍 Regularly inspect the cable for damage to individual veins.
- 🧴 Lubricate the moving parts of the mechanism according to the manufacturer's regulations.
⚠️ Warning: Do not use an electric lift to move the boat along the shore or on the back. The device is designed only for vertical or near vertical lift of the motor.
Common mistakes in selection and use
One of the most common mistakes is to buy a winch back-to-back in power. If the engine weighs 40 kg, it would be a mistake to buy a device with a load of 50 kg. The engine will run at its limits, heat up quickly and can burn. Always take a device with a double margin of safety.
Another mistake is ignoring the battery status, because a weak or old battery pack will not be able to produce the required starting current, which will lead to a voltage drop and improper operation of the electronics of the winch or the engine itself.
Also, users often forget about balancing. If the suspension point is shifted relative to the center of gravity of the motor, it will start to topping up as it rises. This creates a dangerous situation and can damage the lower unit or transom. Before fixing the motor in the upper position, make sure that it hangs vertically.
Use colored Cambricks or tape to mark plus and minus wires when connected, which will help avoid polarity errors in the future if you have to disconnect the wires for maintenance.
You don't have to skimp on fasteners, and the normal ferrous metal will rust in one season, it will weaken, and it can burst under load. stainless steel High quality galvanizing ensures reliability.
A properly selected and installed winch pays off in one season, keeping your health and nerves healthy, and keeping expensive equipment safe.
FAQ: Frequently asked questions
Can I use a car battery to power a winch?
Yes, it is possible, but it is not recommended to do this as a primary power source: starter batteries are not designed for long-term energy return and deep discharges; for frequent use, it is better to purchase a special traction battery (GEL or AGM).
Do I need to remove the engine from the winch when transporting a boat?
Most of the time, yes, and although the winch holds the motor, vibrations on public roads can damage the lifting mechanism or the mounting assemblies, and it also creates additional wind loads.
What to do if the battery is down and the motor needs to be lowered?
Most high-quality electric winches have an emergency lowering mechanism (usually manually unlocking the brake or the ability to rotate the shaft manually).
Is the electric lift suitable for motors with a long leg?
Yes, the type of foot (S, L, XL) is irrelevant to the lift itself, only the weight is important, but when installing the engine, you need to take into account the dimensions of the engine in the elevated state, so that it does not rest on the bottom of the boat or seat.
How to store a winch in winter?
The best way to remove the device, thoroughly wash it with fresh water, dry and lubricate it with conservation grease, and store it in a dry room at plus temperature, removing the terminals from the battery.
