Many owners of Soviet water technology are thinking about creating a hybrid of the Windy outboard motor, seeking to breathe new life into the time-tested unit, not just a desire to save money, but also a way to get a unique device that combines the reliability of classical mechanics with modern electric propulsion or increased power. tuning Such engines have become a whole direction in the environment of water motors, where an individual approach to operation is valued.
Constructive simplicity Wind This makes it an ideal candidate for experimentation, allowing you to implement custom solutions without losing basic functionality. In this article, we will discuss in detail how the hybrid of the outboard motor Winds is implemented, which components require improvement and what should be avoided when self-assembling.
Before starting work, you need to clearly understand that any upgrade removes the device from the warranty (if it is still relevant) and requires the master to have a deep knowledge of the device. lower unit But the result often exceeds expectations, turning an old motor into a reliable assistant for quiet fishing or maneuvering in shallow water.
Concept and objectives of hybrid
The main idea pursued by the hybrid of the outboard motor Winds is to eliminate the main shortcomings of the original design: high fuel consumption, noise and complexity of starting. electric It's based on the existing lower unit or the creation of a benzo-electric circuit, which allows you to take advantage of the electric motor when trolling and keep you able to drive under the ICE at long distances.
Another variant of the hybrid is the installation of the engine from another technique, for example, from a chainsaw or a motorcycle block, on lower unit. Wind 8 or Wind 12.This scheme allows you to significantly increase the life of the piston group, since modern two-stroke and four-stroke donor motors are often more reliable than Soviet counterparts. gearbox.
When creating a hybrid, the key is to keep the entire unit balanced. Shifting the center of gravity can lead to vibrations that will destroy the boat's lower unit or transom. It is critical that the weight of the new power unit does not exceed the weight of the regular engine by more than 15-20%, otherwise it will require outweighing the lower unit.
⚠️ WARNING: When installing a more powerful donor engine, be sure to check the strength of the lower unit. Staff lower unit Wind may not withstand increased loads on twisting with a sharp gas.
The engineering challenge is complicated by the need to pair the shafts. If you're making a hybrid of a Wind outboard motor with an electric motor, you're going to need to make an adapter that will keep the knot coaxial and tight, and the slightest skew will cause the glands to wear out quickly and get water inside the lower unit.
Required tools and materials
A high-quality hybrid assembly project will require not only a technical mindset, but also a specific set of tools. Without quality equipment, it is almost impossible to create a reliable hybrid of the outboard motor Vetok, since high precision parts processing is required.
You will definitely need a lathe or access to turner services to make transition bushings and flanges. fittings, including dynamometer keys for precise tightening of the fastener, which is critical for vibrating nodes.
- 🔧 A complete set of metric keys and heads, including those lengthened to access hard-to-reach locations in lower unit.
- ⚡ Multimeter and soldering station for working with the electric part of the hybrid circuit and sensors.
- 🛠️ A bar and a micrometer for controlling the size of the interfaced parts of the shaft and bushings.
For mounting of knots use only high-strength bolts of strength class not lower than 8.8, and ideally - 10.9. Conventional fasteners may not withstand vibrational loads characteristic of work. crankshaft at high speed.
Sealing of the nodes is another important aspect: use high-quality anaerobic sealants and glands that are resistant to gasoline and oil. The hybrid of the wind outboard motor should not become a source of pollution of the reservoir, so you can not save on consumables for maintenance.
Electrification: installation of an electric motor
The most popular upgrade is the electric-gasoline hybrid. electric-motor It can be used on the normal engine's flywheel or directly on the propeller shaft, allowing you to move in quiet modes without fuel consumption or noise.
To implement such a scheme, ready-made solutions for bicycles or homemade bikes based on motor wheels are often used, adapting them to landing dimensions. WindThe key element here is the controller, which controls the rotational speed and direction of rotation, ensuring smoothness of the stroke.
Calculation of the required capacity of the AKB
To ensure 2-3 hours of electric travel at a motor power of 500-700 W, you will need a lithium battery with a capacity of at least 20 Ah (at a voltage of 24-36V).
Installation of the electrical part requires careful isolation of all contacts. The hybrid of the outboard motor of the Winds is in constant contact with water, so even spray can cause short circuits. All connections must be soldered and protected by shrinkage or filled with compounds.
It is important to provide a cooling system for the electric motor if it is installed in a closed casing. Although water is available outside, direct contact with it of electrical parts without proper tightness is dangerous. Often air cooling is used, with the output of warm air through the pipes above water level.
⚠️ Warning: Never connect an electric motor directly to a battery without a controller, resulting in instantaneous combustion of the windings or battery failure.
Mechanical reworking of lower unit
If your goal is not electrification, but power gain by replacing the ICE, the bulk of the work will be done by the mechanical part, and the Windy boat hybrid in this case is a symbiosis of the new engine and the standard lower unit, the main task is to dock the shafts.
The staff shaft Wind It has specific slits and lengths, and when you install a chainsaw motor, Husqvarna or Stihl) or the motor unit often requires the manufacture of an intermediate shaft, which shaft should compensate for the difference in diameter and ensure the transmission of torque without beating.
- ⚙️ Manufacture of a transition flange for fastening the new engine to the lower unit while maintaining the angle of inclination.
- 🔩 Selection of bearings capable of withstanding axial loads from the screw under the new installation scheme.
- 💧 Modernization of the system of lower unit lubrication, as the regular may not cope with new modes of operation.
Pay special attention to the gearshift system. reverse-reducer Wind It's reliable, but if you increase power dramatically, it can require you to reinforce your cams or replace materials with stronger alloys, and the weak point is often the thrust switch, which is better replaced by the cable from more modern motors.
☑️ Checking of the mechanical part
Comparison of specifications: state vs hybrid
To understand the effectiveness of the upgrade, it is worth comparing the basic parameters: a hybrid of the outboard motor Winds, assembled correctly, can outperform the original in a number of ways, but it is important not to lose reliability. Below is a table showing the potential changes.
| Parameter | Staff Windy-8 | Hybrid (Electric traction) | Hybrid (Chancesaw motor) |
|---|---|---|---|
| Power | 8bhp. | 1-2 hp (equivalent) | 5-7 hp (real) |
| Noise level | Highly | Minimum | Medium/High |
| Fuel consumption | ~3-4 l/h | 0 l/h (electric) | ~1.5-2 l/h |
| Resource to T | ~500 motor-hours | 2000 hours | Depends on the donor. |
As you can see from the table, the electric hybrid loses at top speed, but it wins in economy and comfort. Installing a chainsaw engine gives you a gain in fuel consumption, but requires careful tuning. carburetor for a stable job.
Weights also change. The electric hybrid can get heavier because of the battery, whereas the saw engine option is often lighter than the original, making it easier to transport the boat, and the choice depends on your priorities: speed or autonomy.
Setup and first start
When you build the hybrid, you have to start the first thing, and the wind turbine hybrid requires running, even if you're using new parts, and you don't have to give it full gas, you have to check all the systems at idle speed.
First, check for oil and water leaks, start the engine and let it run for 5-10 minutes, periodically adding gas, monitor the temperature of the cylinder head and the gearbox body, if it warms more than usual, silence and look for the cause.
Check the ignition system. On hybrids with electronic ignition (e.g., from the vortex It's important to set the angle of advance correctly, and if you don't set it right, you can detonate and destroy the piston group.
⚠️ Warning: First run only on a barrel of water or in a pond, working lower unit "dry" even for a minute guaranteed to disable the pump and the ossuaries.
If everything goes well, you can go to field trials. The Winds' outboard hybrid must be able to keep idling confidently and not deaf when the throttle is opened abruptly. Any foreign knocking or vibration should be the signal for immediate stop and diagnosis.
The success of a hybrid depends on 20 percent of the idea and 80 percent of the quality of the transition units and sealing. Don't skimp on materials!
Frequently Asked Questions (FAQ)
Can I put a four-stroke engine on the wind?
Theoretically, it can, but it would require a major overhaul of the lower unit: Four-stroke engines have a different lubrication system (cartridge), and their shafts often lack a way to lubricate the lower unit, and they are heavier and require a strict vertical position, which is difficult to implement in a turning lower unit. Wind.
Which screw is best used for hybrids?
An electric hybrid often requires large-step propellers, as electric motors give maximum torque at once. For a gasoline hybrid with low power (from a saw), on the contrary, you need a screw with a reduced diameter or pitch so that the engine can spin to working turns.
Should we change the lower unit lubricant when hybridizing?
Yes, it is. When changing operating modes and temperature loads, the standard mixture of "two-stroke oil + gasoline" or solidol may not cope. It is recommended to use specialized transmission oils for outboard motors, resistant to emulsification.
Is the cost of creating such a hybrid justified?
Financially, rarely if you buy anything new, and economically, if you already have parts, an old engine disassembled, or access to free parts, otherwise it's easier to buy a new Chinese engine, and hybrid is more of a hobby and an engineering challenge than a way to save money.
