Control of the outboard motor, especially a powerful four-stroke or heavy two-stroke, often becomes a real test for the back and hands of the owner of the boat. Electrolift for outboard motor It's a device that fundamentally changes the way we prepare for the water, turning hard physical work into a light push of a button. PVC boats and boats have long appreciated the convenience of a mechanized trans-shipment system that allows us to raise and lower lower unit effortlessly.
The modern market offers many solutions, from simple winches to complex hydraulic systems, and choosing the right option requires an understanding of technical nuances. Electric lift Not only does it lift the motor, but it also ensures that it is securely fixed while driving, which is critical for safety, but in this article we will discuss in detail the design features, installation methods and subtleties of operation of this useful equipment.
Design features and principle of work
The basis of any electric lift is a powerful electric motor, which through a system of gears or worm gear drives the propeller. It is the screw pair that converts the rotational movement of the motor shaft into the translational movement of the carriage on which the carriage is fixed. boat-engineThis design ensures smooth running and the ability to hold significant weight in any position without slipping.
The body of the device is usually made of stainless steel or aluminum with anti-corrosion coating, since Constant contact with salt or fresh water It's a major wear factor, and inside the machine are end switches that prevent the rod from going outside the operating stroke, which protects the mechanics from breaking when it reaches the extremes.
The control system can be implemented through a wired remote, a remote button on the tiller or even a wireless key fob, which adds additional comfort. Hydraulic cylinder In more expensive models, replaces the screw pair, providing even greater smoothness, but requiring more complex maintenance and the presence of hydraulic fluid.
An important element is the mounting bracket, which must match the geometry of the transom of your boat. Incorrectly selected base can lead to skewed motor and uneven load on the lifting mechanism.
⚠️ Note: When choosing a model, be sure to consider not only the weight of the engine, but also the dynamic loads that occur when hitting a wave.
Criteria for Electrolift Selection
The first thing to look at when buying is the payload of the device. If your engine weighs 50 kg, it would be a mistake to buy a 50 kg elevator; you need a margin to keep the mechanism from running to the limit. Traction force It directly affects the lift speed and durability of the electric motor.
The stroke length of the rod is the second critical parameter, and it should be sufficient to fully lift the lower unit out of the water, but not excessive, so as not to cause problems with setting the low transom. Standard models usually have a stroke of 300 to 500 mm, which is suitable for most civilian boats.
The materials and the degree of IP protection also play a crucial role. sea-stainless steel 316, since ordinary aluminum may be subjected to electrochemical corrosion.
- 🚀 Load capacity: Choose a model with a power reserve of at least 20-30% of the weight of the engine.
- 🔋 Power voltage: Make sure that the 12V or 24V system is compatible with your onboard network.
- 🛡️ Protection: The minimum protection class must be IP67 for submersible parts of the mechanism.
- ⚙️ Type of fastening: Check the bracket’s compatibility with the thickness and shape of your transom.
Preparation for DIY installation
The installation of the electrolift is a process that requires accuracy and accuracy, because safety depends on the quality of the installation. Before starting work, the transom of the boat must be thoroughly cleaned of dirt, grease and old sealant. The surface must be completely dry and fat-free to ensure reliable adhesion of the fasteners.
You will need a standard set of tools: a drill with a set of drills for metal, wrenches, marker, roulette and possibly a corner grinding machine for fitting elements. Electrical wiring circuit It should be studied in advance to correctly calculate the cross section of the cable and select a fuse.
It is recommended to try on the elevator beforehand on the transom, without fixing it completely, to determine the optimal position. This will avoid situations when the raised engine rests on the elements of the boat's design or squashing on board.
☑️ Preparation for installation
Step-by-step installation instructions
Start by marking the holes to hold the elevator base, use the template from the manual, or apply the device base to the transom and mark the holes centers with a marker, and it's important to keep the symmetry in place so that the load is distributed evenly throughout the mounting area.
Drill the holes with a drill of the appropriate diameter, trying to keep the tool strictly perpendicular to the surface of the transom. If the trunk of the sandwich structure (wood inside, fiberglass outside), the edges of the holes must be treated with epoxy resin to protect against moisture entering the inside.
Set the fasteners by running them through the holes, and fasten the elevator on the back with nuts with wide washers. sealer around each hole and under the base of the device before the final puff.
Moment of nut tightening: 15-20 Nm (check in 24 hours)After mechanical fixation, proceed to the electrical connection. Lay the battery cable to the elevator, be sure to install the fuse in the break of the plus wire as close as possible to the battery. Connect the wires according to the color marking or scheme in the instructions.
⚠️ Attention: All electrical connections must be protected by adhesive-layered heat-shrinking tubes or filled with compounds, and contacting moisture will lead to oxidation and system failure.
Setup and first activation
Before the first run, check all connections again and make sure that nothing interferes with the movement of the rod. Turn on the power and press the lift button, controlling the movement of the carriage. The course should be smooth, without jerks and extraneous sounds such as grinding or hum.
Check the end switches by bringing the rod to the top and bottom positions. The motor must automatically stop when it reaches the end points. If this does not happen, immediately turn off the power and check the adjustment of the sensors.
Perform several cycles of lifting and lowering with the motor fixed (without starting the engine) to ensure the stability of the structure.
What to do if the elevator is buzzing?
The buzzing may indicate a mechanism skewed or lack of voltage. Check the battery charge and make sure all the mount bolts are tightened evenly. If the noise persists, a screw pair lubrication may be required.
Maintenance and care
Regular maintenance extends the life of the electrolift and prevents sudden breakages on the water. After each operation in salt water, the device must be washed with fresh water to remove the residue of salt, which is the main enemy of the metal.
Once a season, it is recommended to lubricate the propeller or joints of a special waterproof Do not use conventional lithium lubricants that are quickly washed out by water.
Periodically check the status of electrical contacts and the integrity of the insulation of the wires. Mechanical damage to the insulation can lead to short circuit and failure of all onboard electronics.
| Frequency | Action. | Materials required |
|---|---|---|
| After every fishing trip | Freshwater flushing | Hose with water, soft brush. |
| Once a month | Visual inspection of anchorages | Wrench, flashlight. |
| Once a season | Lubrication of the mechanism | Sea lubricant, rags. |
| Once a year. | Electrical checks | Multimeter, insulation tape |
Frequent errors in operation
One common mistake is to try to lift the motor when it is in gas mode or jammed with algae, which puts a critical strain on the elevator gearbox and can cause the gears to break.
Ignoring the signs of corrosion in the early stages is also dangerous, and if you notice the first rust spots, you need to clean them immediately and coat them with corrosion-resistant compounds, otherwise the process of breaking the metal will go faster.
Some users forget to fix the motor in the transport position after lifting, relying only on the elevator. However, with a strong shaking or hitting the wave, the mechanism may not withstand dynamic load without additional insurance.
To protect the screw pair from dirt and sand, you can make a simple case from dense fabric or use a corrugated protective casing, which is sold in auto stores.
Advantages of Using Automation
The electrolift frees your back and allows you to focus on pleasure from fishing or cruising, especially for people with limited physical strength or for owners of heavy motors over 15 hp.
Automating the lifting process also improves safety, because it eliminates the risk of a wet motor slipping from your hands into the water or onto the deck, and you have complete control of the process while in a safe zone.
In addition, the presence of an electrolift increases the liquidity of the boat at the resale, as buyers highly appreciate the additional comfort and modern equipment of the boat.
The Elevator is an investment in your health and comfort that pays off in the first season of active operation.
FAQ: Frequently asked questions
Can I install an electrolyte on a PVC boat?
Yes, there are special models with adapters for inflatable transaters, but it is important to make sure that the stiffness of the transom is sufficient to perceive the load, or use additional reinforcing plates.
Does the electric lift drain the battery?
The energy consumption is only when you lift or lower it, which takes a few seconds, and for a standard cycle, 12V of a battery with a capacity of even 20 Ah is enough, because the current consumption is short-term.
Should I take off the engine in winter or will the elevator withstand the cold?
The elevator itself can be left on the boat if it is made of quality stainless steel, but the electric motor and control unit are better dismantled and stored in a warm dry room to avoid condensation inside.
What to do if the water is lost?
Most models are equipped with an emergency manual lifting mechanism (usually a removable handle) that allows you to lower or lift the motor manually in the event of battery discharge.
