Soviet outboardThe vein, which is widely used on rivers and lakes, still causes heated debate in the circles of water engines. Wind 12It's a symbol of accessibility and maintainability for millions of fishermen, and despite its age, it's a very interesting and interesting machine. Reviews of the outboard motor Winds 12 They continue to appear on specialized forums with enviable regularity, some users call it "unkillable", while others complain about the constant problems with the ignition system and carburetor.
In this article, we will conduct a detailed analysis of the technical specifications, consider the real experience of operation and weigh all the pros and cons of buying or restoring this device. Two-stroke engine Designed in the 1960s, internal combustion has a unique architecture that requires the owner to have certain knowledge and skills. Wind This will help you avoid common mistakes and extend the life of your boat, and we will analyze why this motor is still relevant and whether it is worth contacting in modern conditions.
Objectivity in the assessment requires consideration not only of data-sheet figures, but also of what owners face in real life. Plunge The propeller, fuel consumption and noise are the key parameters that interest a potential buyer: Let's look at what lies behind the nostalgic flair and where the harsh truth of the operation of Soviet equipment on the water lies.
Technical specifications and design features
Construction Wind 12 It's based on a time-tested crank-shaft circuit, and it has two cylinders in a row, and it's producing 12 horsepower at 5,000-5,500 rpm. Workload It's 220 cubic centimeters, which is a solid figure for a two-stroke, weighing about 26 kilograms, making it relatively easy to transport over short distances, although carrying it alone still requires physical training.
The power supply system is implemented through a carburetor K-33 or later modifications that provide a mixture. Fuel mixture It's a 1:25 ratio, which means that 25 liters of gasoline require 1 liter of oil, and the crankshaft bearings and rods are lubricated with this mixture, so the quality of the oil plays a critical role in the engine life. piston-group.
Use only quality two-stroke oils labeled TC-W3 to avoid the formation of soot on candles and pistons.
The engine cools is water-induced, and the water is sucked through the intake in the lower unit and circulated through the channels in the cylinder block and head. Thermostat It's not in the classical sense, but it's regulated by the circulation and heat transfer through the aluminum casing, which makes the system simple, but it depends on the purity of the waterways.
Real experience of operation: pros and cons
Analyzing reviewsAnd you can see the advantages that keep this engine in service, and the great advantage is that it's very maintainable, and you can find parts in almost any garage or you can buy them on the ad, and the design allows you to do it. maintenance With a minimal set of tools, many craftsmen have learned to restore. Winds to the state of "new", using available means.
But there's a downside to this: Electronic ignition, especially on earlier magdinos, is often a hassle. Switch And the sensors can fail at the most inopportune moment, requiring replacement or careful adjustment of the gap, and users often complain about vibration that is transmitted to the transom of the boat, especially at high revs.
- 🔧 High availability of spare parts and simplicity of engine design.
- ⛽ The possibility of working on AI-76 gasoline (in modern conditions it is adapted to AI-92).
- 🌊 Good traction at low revs, which is important for trolling.
- 🔊 Increased noise and vibration levels compared to modern analogues.
- 🔥 The tendency to overheat when driving at full speed for a long time.
It is important to note that many negative reviews are associated with improper running or using an old engine without first defecting. Resource The engine depends on the quality of the assembly and compliance with the temperature regime. If the engine regularly overheated by the previous owner, the risk of piston bullying or piston burnout increases significantly.
Problems with the start and ignition system
The most common problem faced by owners Wind 12 It's a difficult start. It's often not the engine itself that's causing it, it's the state of the engine. spark plug Electrode increments can be caused by misproportion of the mixture or by the use of low-quality oils, and regular clearance checks and candle cleaning are mandatory before each season.
A magdino-type ignition system requires fine-tuning the gap between the magnetic circuit and the coils. If the gap is too large, the spark will be weak, especially at high revs. If it is small, the coils may break or overheat. Sparkling This is a key to the stable operation of a two-stroke engine, where many owners switch to electronic ignition from other models or assemble homemade circuits based on generators.
⚠️ Warning: When checking for a spark, never hold a candle in your hands without insulation. High voltage can lead to an unpleasant shock, as well as damage to the switch if the circuit is not closed to the mass correctly.
Another nuance is the state of the contacts under the flywheel, and oxidation or weakening of the mount bolts of the magnetic wire leads to unstable operation of the engine at idle speeds. flywheel The flywheel must sit tightly, and the cone landing must not have backlashes. The flywheel is a serious malfunction requiring the replacement of the crankshaft or the flywheel itself.
How to check the switch without a stand?
You can use a simple tester in the vertebral mode of the diodes, the resistance between certain conclusions should differ in the forward and reverse direction, but the accurate diagnosis is possible only on an oscilloscope or by replacing it with a known serviceable one.
Carburetation and fuel system
carburetor K-33, which is fixed on Wind 12It's considered a pretty reliable node, but it needs attention, and the main problem is tightness, and over time, the rubber seals and gaskets tan, which leads to air suction. Depleted mixsuction causes the engine to overheat and lose power, and visually it's a whitish plaque on candles and a clap in the carburetor.
The adjustment of the quality of the mixture is made by screws on the carburetor, you need to achieve stable operation at idle speeds and no failures when the throttle is opened sharply. Float chamber It needs to be clean, and the needle valve tightly shuts off the fuel supply, and often owners face a fuel overflow, which leads to increased consumption and smoke.
☑️ Diagnosis of the carburetor
The fuel hose and pear also require periodic replacement, and the rubber ages, cracks, and can let fuel or air through. Fuel filterThe water in the fuel system is the number one enemy of any fuel system, causing corrosion and impaired mixing.
Comparison of specifications with competitors
To understand the place Wind 12 In today’s market, it is advisable to compare its parameters with its closest competitors, such as: Yamaha 9.9 or Hidea 9.9Now, it's not entirely correct to compare Soviet technology to modern Japanese or Chinese technology because of the different eras, but it's useful to understand evolution.
| Parameter | Wind 12 | Yamaha 9.9 (2T) | Hidea 9.9 |
|---|---|---|---|
| Power (hp) | 12 | 9.9 | 9.9 |
| Weight (kg) | 26 | 36-38 | 34-36 |
| Fuel consumption (L/h) | 6.5 | 5.5 | 5.5 |
| Ignition system | Magdino/Electronic | CDI | CDI |
| Price (new/b.o.) | Low/Mediocre | High. | Medium |
The table shows that Wind It's a big winner in weight and cost, but it's a big loser in efficiency and reliability. Modern engines are quieter and have a better lubrication system for bearings, which increases their lifespan. But for short fishing trips, a 10 kilogram difference can be a big factor.
Tuning and modernization: is the game worth the effort?
Many owners do not stop at the factory configuration and begin to modernization The most popular type of tuning is the installation of an electronic ignition system, which allows you to forget about adjusting the gaps, improves spark formation and facilitates start-up. Electronic ignition makes the engine more smooth and stable throughout the rev range.
The second popular option is to replace the screw. A standard screw often doesn't fit the operating conditions or the type of boat. Installing a modified pitch screw can increase the speed of the propeller. speed-up Or, conversely, to improve traction for heavy boats, it's important not to overload the engine by tailoring the propeller to fit a particular boat and load.
Competent tuning can turn the Wind 12 into a reliable assistant, but requires deep knowledge of the engine and accuracy in execution.
You can also see a high-performance water pump from other models, or you can refine the existing one, and the cooling enhancement allows you to operate the engine at full speed without the risk of overheating, which is especially true in hot weather or when you're driving against the current. Thermostatation (installation of a homemade thermostat) also helps the engine to go into working mode faster.
Maintenance and storage tips
In order to Wind 12 It has been in service for a long time, and you have to follow simple rules of operation, and after every trip in salt water or dirty river water, the engine should be washed with fresh water. Corrosion The main enemy of aluminum alloys and steel parts, and you have to pay special attention to lower unit and the attachment.
When you can preserve it for the winter, water must be drained from the cooling system, and for this purpose, the motor is installed in an upright position and the remaining fluid is drained. Engine conservation It also involves treating the internal cavities with oil through candle holes and storing them in a dry room, and it is better to leave the fuel tank empty or completely filled with the addition of a stabilizer.
⚠️ Warning: Never store a motor with water in a cooling system in an unheated room in winter. frozen water will expand and may rupture the cylinder block or water pump body.
Regular lubrication of all rubbing parts, checking the tightening of the mount bolts and the condition of the lower unit are the key to successful navigation. Prevention It takes less time than water repairs, and you can bring spare candles, a tool kit and a spare fuel mix.
Frequently Asked Questions (FAQ)
Which gasoline is best used for wind turbine 12?
The plant recommended AI-76, but in modern conditions the best choice will be the best. AI-92 The use of the AI-95 is impractical and can lead to overheating due to longer burning.
Why does the 12th wind stop at high speed?
Most often this is due to a violation of the fuel supply (a chick is clogged, a hose is clamped) or problems with the ignition system (breaking the coil to the mass, a malfunction of the switch). tightness Crawlers.
Can I put the 12th Wind on an inflatable boat?
Yes, you can, but you have to consider the weight of the engine (26 kg) and the force of thrust. For small PVC boats, it can be a bit heavy, and a powerful jet from the propeller can damage cylinders without special protection.
How often should you change the oil in the gearbox?
Oil in the gearbox Wind It is recommended to change once a season or every 50 motor hours. If the oil has acquired a milky shade, then the sealing of the osluds is broken and water has got into the gearbox - urgent replacement of seals is required.
