Control of a boat with a powerful outboard motor becomes a real test for the back, if each time you have to manually move the heavy unit from the trolley to the transom. Boat-engine lift It's not just a convenient option, it's a necessity for people who value their health and time, and modern lifting mechanisms allow one person to move a tens of kilogram engine from a horizontal position to a working one without superhuman effort.
The boating market offers many solutions, from simple mechanical cranes to complex remote-controlled electrical systems, depending on your type of boat, your weight. PM In this article, we will discuss in detail how to choose and assemble this useful accessory so that fishing begins with joy, not with low back pain.
There is a misconception that elevators are only needed for very heavy engines with a capacity of more than 50 hp. Yamaha or Tohatsu With 15-20 hp, they weigh more than 40 to 50 kg, and if you put them on a transom can be traumatic, and a well-chosen lift turns this routine into a slight lever movement or the press of a button.
Design features of lifting mechanisms
All existing devices on the market can be divided into two large groups: mechanical and electrical. Mechanical elevators (often called crane beams or lift racks) operate on the principle of lever and counterweight or using a winch. They are reliable, do not require connection to the onboard network and are usually cheaper than their electric counterparts.
Electric models are equipped electric motorThese systems are often integrated into the design of the transom wheels or are a separate module mounted on the frame, and their main advantage is the ability to control one hand, which is especially true when the second is engaged in holding the mooring end or balancing the boat.
The most important piece of design is the gripper, which is attached to the engine's lower unit, which has to be rigidly fixed so that the engine doesn't sway when lifting. Many models have adjustable mounting systems that fit different types of mounts. lower unit and the distance between the bolts of the motor to the transom.
- 🛠️ Shell material: Aluminum alloys with powder painting or stainless steel for maximum protection against corrosion.
- ⚓ Load capacity: Most models are designed for weights up to 150 kg, which covers 95% of all outboard motors.
- 🔧 Type of installation: Removable structures that can be quickly dismantled, or stationary, welded to the frame.
Criteria of choice: what to pay attention to
Before buying, you need to know your weight. outboardThe elevator should have a safety margin of at least 20-30% of the real weight of the engine. If you plan to change the engine to a more powerful one in the future, you should immediately take a model with a large payload margin so as not to buy new equipment.
The second critical parameter is compatibility with the design of the boat. PVC boats They often use removable racks that are attached to a balloon or a transom board without damaging the material. Metal and fiberglass boats are suitable for more massive structures that are attached directly to the transom or frame.
Notice the lift height. The mechanism has to lift the motor high enough that the screw and anti-cavitation plate are completely out of the water, but it allows the engine to be lowered into the operating position with the correct depth of immersion. telescopicThis allows you to adjust the lifting height depending on the model of the motor.
When choosing an electric elevator, be sure to check the current consumed. Powerful models can quickly discharge a weak battery if you forget to turn them off.
Instructions for installing the elevator on the transom
Installation of the lifting device requires carefulness and adherence to technology, since it is a matter of safety of heavy loads above deck. An error in attachment can cause the engine to fall and damage to the transom or the engine itself. Before starting work, make sure that the surface of the transom is clean and fat-free.
The most common way to install a mechanical lift on a PVC boat is to use special brackets that cover cylinders, or attachments to the transom board through holes. In the case of a hard transmolator, drilling is the most reliable way to fix. Use only stainless bolts and nuts, smearing the joints with sealed sealants.
☑️ Checklist before installation
If you're installing an electrical system, pay special attention to wiring. The cables must be reliably protected from moisture and mechanical damage. The battery connection must be through a fuse of the appropriate value to protect the onboard network from short circuit.
⚠️ Attention: Do not install the elevator if its construction interferes with the control of the tiller or access to the fuel tank in the working position.
Comparison of mechanical and electrical systems
The choice between manual and automatic drive often comes down to budget and personal preferences. Mechanical systems are easier to maintain: there's nothing to break except, perhaps, a cable or bearings, they work in any environment, they're not afraid of frost and moisture.
Electric elevators provide comfort, but require regular contact maintenance and battery charge control. The table below compares the main specifications of both types of devices to facilitate choice.
| Characterization | Mechanical elevator | Electric elevator |
|---|---|---|
| Speed of ascent | Depends on the operator's strength | Tall, stable. |
| Dependence on ABC | No. | Complete. |
| Structure weight | Easy. | Heavyer (because of the engine) |
| Price. | Affordable | High. |
The secret of the durability of electric elevators
After each outing, especially in salt water, be sure to spray the electrical contacts and the elevator engine with a protective spray (for example, WD-40 Specialist Corrosion Inhibitor), which will prevent oxidation and prolong the life of many times.
Safety technique during operation
Using a lift requires following certain rules. Never be under a raised motor unnecessarily. Although modern fixtures are reliable, there is always a risk of slipping the gripper or breaking the cable (if improperly operated).
Regularly check the condition of cables, chains and fasteners. Metal fatigue If you notice a scuff on the cable or a backlash in the joints, replace the defective part immediately.
When lowering the motor in the water, monitor the process visually. Make sure that the lower unit enters the water smoothly, without distortions that can damage the transom or mounting system. After lifting the motor, always lock it with a stopper if the elevator design foresees it.
The main rule is never to leave the motor hanging on a cable or winch for a long time (for example, overnight or during a long parking lot).
Maintenance and care of the lifting mechanism
For an elevator to be faithful for years to come, it needs to be taken care of. After every use, especially in salt water, the mechanism needs to be washed with fresh water. stainless-steel poor quality.
The moving parts -- the spin axes, the hinges, the winch drum -- require regular lubrication. Use special marine lubricants that are not washed away by water and retain their properties at low and high temperatures. Regular engine oil can quickly wash or thicken in the cold.
Once a season, you have to do a complete re-engineering of the fasteners, and you can use the wrinkles when you're running the motor and when you're in the wave, and you can use the thread lock when you're building to make sure you're safe.
⚠️ Attention: Do not use general-purpose lithium lubricants for lubricating moving parts unless they are marked "Marine"; they can break down rubber seals and wash out quickly with water.
Frequently Asked Questions (FAQ)
Can I install an elevator on a soft-translated boat?
Yes, there are special models for soft-trans boats, which have a wide support pad that distributes the load over a large area, or are attached to cylinders with special slings without damaging the PVC material.
Will the elevator withstand a 100 kg engine?
Most modern elevators are designed for a load of 80 to 150 kg. However, before buying, be sure to specify the maximum load capacity of a particular model in the technical data sheet. For engines heavier than 80 kg, it is strongly recommended to choose models with a double safety margin.
Do I need to remove the motor from the elevator when transporting a boat on a trailer?
It depends on the design of the elevator. Removable models are better dismantled to reduce sailing and weight. Stationary elevators can be left, but make sure that the engine is securely fixed and will not hang around when driving on the highway, creating a dangerous load on the transom.
Is it difficult to install an electric elevator on your own?
The basic installation of the mechanical part is usually simple and takes 1-2 hours. The electrical part requires minimal knowledge of electrical engineering (plugging terminals, installing a fuse). If you can hold a wrench and read the instructions, there should be no difficulties.
Does aluminum rust in salt water?
Aluminum alloys used in marine equipment (e.g. duraluminum) have high corrosion resistance but are not completely stainless. Without proper care (washing and coating with protective compounds), they can be pitting corrosion.
