outboard motor Wind 8 It is considered a legend of the domestic engine industry, which has survived not only its factory, but also the entire era of boating technology. Despite the fact that the production of these units in Naberezhnye Chelny was stopped, thousands of units are still actively plowing the expanses of Russian rivers and lakes. Many owners wonder why this two-stroke engine, developed in the 60s, is still in demand in the secondary market and causes such interest.
The answer lies in the phenomenal repairability and availability of spare parts, which can be found in almost any garage or buy for pennies on the ruins. Construction The engine allows for complex field repairs with minimal tools, which is critical for fishermen and hunters far from civilization. However, modern users often face the dilemma: should we spend time restoring an old unit or should we consider more modern Chinese counterparts?
In this article we will discuss in detail specification We analyze the real owner reviews who faced the operation of the "Wind" in different conditions, and discuss the current pricing policy on the used model. You will learn about the typical "diseases" of this engine, methods of their elimination and understand whether this time-tested unit for your boat is suitable for you.
History of creation and design features
Engine development began in Naberezhnye Chelny in the mid-1960s, when the industry was challenged to create a mass-produced, reliable and easy-to-maintain engine for small craft. Johnson SeahorseHowever, Soviet engineers made significant changes, adapting the design to the harsh realities of operation and available materials. Serial production The engine was launched in 1964, and since then the engine has undergone many modifications, receiving the indexes "M", "H", "E" and others.
One of the key features of the design is the presence of reverse-reducerThis was rare for engines of this power (8 hp), which allowed not only to change the direction of the rotor, but also to use the engine to tow skiers or heavy loads, where you needed to reverse. The float carburetor ensured stable operation in all modes, although it required periodic adjustment, especially when changing the quality of the fuel mixture.
The ignition system on different modifications could differ: from contact with magdino to more modern contactless electronic. Modifications with electronic ignition system are considered the most reliable and preferred for purchase in the secondary market. The body of the lower unit is made of aluminum alloy, which provided good corrosion resistance, although it required regular painting and lubrication for longevity.
Technical specifications and power indicators
Under consideration technical specifications boat-engine Wind 8 It is important to understand that the declared power of 8 horsepower is achieved at certain speeds and a quality fuel mixture. The engine is two-stroke, single-cylinder, with crank-chamber purges. The displacement is 174 cubic centimeters, and the cylinder diameter is 50 mm during the piston 44 mm.
The weight of the engine in running order (without fuel) is about 26 kg, which makes it relatively easy to install on small inflatable boats or light metal vessels. However, when refueled with a full tank (standard tank for 12-14 liters), the total weight increases significantly, which must be taken into account during transportation.
For clarity, we will give the main parameters in a tabular form so that you can compare them with modern analogues:
| Parameter | Meaning |
|---|---|
| Power | 8 hp (5.9 kW) |
| Workload | 174 cm |
| Weight (dry) | 26 kg |
| Fuel consumption | up to 3.2 l/h |
| Tank volume | 12-14 l |
It is important to note that the actual fuel consumption depends on the condition of the engine, the quality of the assembly and operating conditions. At full gas, the engine can consume up to 3-3.5 liters of the mixture per hour, while at cruising speed (about 3000-3500 rpm), the flow rate is reduced to a comfortable 1.5-2 liters.
Fuel consumption and efficiency of operation
Question fuel-flow Like any two-stroke engine, it requires a fuel mixture of gasoline and oil in the proportion specified in the instructions (usually 1:25 or 1:50 depending on the type of oil and year of release of the engine), using pure gasoline without the addition of a special two-stroke oil is guaranteed to lead to piston bullying and engine failure in a matter of minutes.
The engine economy depends heavily on the configuration of the carburetor and the condition of the exhaust windows. If the engine does not pull or smokes more than usual, this is a direct signal of a violation of mixture formation. Optimal regimen The work that balances speed and flow is in the range of 70-80% of maximum power, in which the motor emits a characteristic smooth sound, and the vibration of the body becomes minimal.
⚠️ Warning: Never use automotive oils to make a mixture. Only special oils for two-stroke engines with the labeling
2Tprovide the necessary lubrication of the crank-shaking mechanism and prevent the exhaust system from coking.
The average full-tank range (12 litres) in moderate traffic is about 60-70 kilometers, enough for fishing in the nearest body of water or cruising along the coastline, but when driving against strong currents or wind, consumption can increase by 30-40%, which should be considered when planning long-distance routes.
Typical malfunctions and methods of their elimination
Despite the reliability, the age of most surviving engines dictates its conditions. The most common problem is the leakage of the crankshaft coils, which leads to air sucking and impoverishment of the mixture, manifested in unstable idling and difficult start. Replacing the coils is a simple procedure, but requires accuracy and the presence of tenants.
The second common disease is clogging of the carburetor’s fuel channels and jellyplates, and the residue of old oil and gasoline residues can completely block the fuel supply system. Regular cleaning Carburettor and fuel tank is a prerequisite for smooth operation, and it is also worth paying attention to the condition of the petal valve, which is responsible for timely filling of the cylinder with a fuel mixture.
How do I check the petal valve?
Take the carburetor off and inspect the petals. They should fit tightly to the saddle around the perimeter. If you see gaps or petals have cracks, the valve needs to be replaced or laundered. A loose fit leads to "slaps" in the carburetor and loss of power.
Ignition problems are also not uncommon, especially on magdinos. oxidation of contacts, breakdown of high-voltage wires or failure of capacitors can completely immobilize the boat. Owners are advised to carry a spare candle, ignition coil and a set of tools for rapid diagnosis.
Comparison with modern analogues and competitors
In the modern market of outboard motors Wind 8 It competes mainly with Chinese twin-strokes with 8-9.8 hp and second-hand Japanese Tohatsu or Yamaha engines. The main advantage of the Wind is the price and availability of spare parts. The Chinese counterpart can cost 3-4 times more, and its repair in case of breakdown often turns into a quest to find specific parts.
On the other hand, modern engines benefit in weight, noise, vibration and environmental friendliness, are easier to start, have a more efficient cylinder blowing system, and often have forced lubrication, which eliminates the need to mix gasoline with oil. However, in the harsh conditions of the Russian outback, where service centers are hundreds of kilometers away, the simplicity of the Wind remains its trump card.
If you think of the engine as the main one for frequent trips over long distances, modern analogues will be more comfortable. But as a spare engine or engine for short trips to the nearest backwater, the good old "Wind" will give a head start to many newcomers to the market due to its indestructibility with proper care.
Price on the used market and whether to buy
Cost of the engine Wind 8 in the secondary market varies very widely and depends on the year of production, configuration and technical condition. Motors in the state of "sit and go", have undergone major repairs and painted, can cost from 15 000 to 25 000 rubles.
When buying, be sure to check the compression. For a two-stroke engine, compression in the area of 8-9 atmospheres is considered normal. If the indicator is below 6 atmospheres, the engine will require serious intervention. Also, you should pay attention to the state of the daydvoot: the absence of backlashes in the area of the propeller and gear shift rod indicates a good condition of the gearbox.
☑️ Checking the engine before buying
Buying a Wind is justified if you can hold a wrench and are willing to spend time maintaining your equipment, it is a motor for enthusiasts and practitioners who value independence from service centers, and if you want a "on and on" technique, it is better to consider more modern options, albeit at a higher price.
Owner reviews: real exploitation
Analysis of forums and feedback from owners shows a polar attitude towards this engine, some calling it an “unkillable tank” that starts half-around even after winter downtime. Others complain of constant problems with ignition and carburetor. The difference usually lies in storage conditions and regularity of the conduct. maintenance.
Many users note the high thrust of the engine at low speeds, which is especially appreciated when trolling or driving in overgrown grass areas. The ability to use screws with different pitches allows you to adapt the engine to a specific boat and tasks. Load capacity The boat with this engine allows you to comfortably accommodate 2-3 people with full equipment.
⚠️ Warning: When operating the motor in salt water (at sea), be sure to wash the cooling system with fresh water after each exit. The aggressive environment quickly destroys aluminum alloys and disables the pump.
Owners also praise the versatility of the engine: it is suitable for both PVC inflatable boats 3-4 meters long and for light metal "Kazak", the main thing is to choose the right gear ratio and screw pitch to avoid engine overload.
Frequently Asked Questions (FAQ)
What is the best gasoline for Wind 8?
The AI-92 gasoline is optimally used, higher octane fuels will not give power gain, and low-octane fuels can cause detonation, the main thing is freshness of the fuel and proper mixing with oil.
Why does the engine stop at high speeds?
Most often, this indicates a violation of the fuel supply (a jet lag is clogged, a net in the tank is clogged) or a violation of the tightness of the fuel system (air sucking), also the cause may be a malfunction of the ignition system (a failure of the coil at high revs).
Can Wind 8 be used on a 5-meter boat?
It's possible, but it's slow, especially when it's fully loaded, and it's going to run at the limit of its ability, which will increase fuel consumption and wear and tear, and it's going to be a boat that's going to prefer 10 to 15 hp.
How to Preserve the Motor for the Winter?
You need to drain the remnants of the fuel mixture, blow out the carburetor, lubricate the cylinders through the candle hole with a special preservative or oil, and store the engine in a dry room in an upright position.
Wind 8 is the choice of a rational owner, ready to take care of the equipment in exchange for reliability and cheapness of ownership.
For long-term storage, lubricate exposed metal parts (thrusts, shafts) with a thick lubricant to prevent corrosion from moist air.
