Choosing a reliable outboard motor for a small boat is often a challenge for fans of fishing and recreation on the water. boat-engineIt has proven to be an affordable and unpretentious solution for small-sized vessels, designed to meet the specifics of domestic water bodies, which require not so much high speed as a confident start and the ability to work in difficult conditions.
Many aqueous motorists are paying attention to this model because of its maintainability and the affordable cost of spare parts. Volgar It does not require high-octane fuel and complex maintenance. A unique feature of the design is the possibility of using as fuel a mixture of gasoline A-76 or AI-92 with oil in a ratio of 1:25, which significantly reduces operating costs.
In this article, we will discuss in detail the specifications, design features and real-world experience of this engine, you will learn why this engine has been popular for several decades, and whether it is worth buying for your PVC boat or boat in the current conditions.
History of the engine and concept
The engine was developed at a time when industry was struggling to make the engine as simple and cheap as possible for the mass consumer, and engineers wanted to have an engine that could be repaired in the field with a minimum set of tools. Concept It was a rejection of complex electronic ignition systems in favor of magdinos, which is characterized by high reliability and durability.
Production was established at facilities that previously produced other equipment, which allowed to quickly saturate the market with affordable engines. Volgar It became a kind of workhorse for fishermen and hunters who didn't need record speeds, and it focused on low-speed traction and idling sustainably.
The design has undergone minimal changes over the years, which indicates that it is a well-developed design, but it is the conservative approach that has allowed the engine to be devoid of many of the more complex models’ “childhood diseases” and is now regarded as a classic of domestic motor engineering in the small power class.
⚠️ Attention: When buying a used motor, pay special attention to the condition of the lower unit pipe. If it has strong dents or traces of through-type corrosion, restoring tightness can cost more than the cost of the engine itself.
It's important to understand that this motor was created in a different era, when environmental regulations and noise levels were not the number one priority, so modern comfort requirements can conflict with the specifications inherent in design.
Technical specifications and design
The engine is a two-stroke gasoline unit with crank-chamber purge. The power is 9 horsepower, which is the optimal value for boats with a length of 3 to 4 meters. The weight of the power unit in the transport position (without fuel and oil) is about 26 kilograms, which allows it to be transported in the trunk of a passenger car.
The cooling system is forced, off-shore water, and it allows for efficient heat removal even when you're working at full speed for long periods of time. Transmission It has one forward gear, which simplifies the design of the gearbox and reduces the likelihood of breakdowns, and is controlled by a tiller located on the lower unit.
Below is a table with basic technical data to help you compare Volgar with competitors:
| Parameter | Meaning |
|---|---|
| Power | 9bhp. |
| Workload | 223 cm |
| Number of cylinders | 1 |
| Maximum speeds | 4500-5000 rpm |
| Type of fuel | Gasoline + butter |
The engine's dimensions allow it to be mounted on transverses up to 380 mm high. The suspension design provides for the ability to recline the engine to overcome shallow water or during transportation, this is especially true for owners of inflatable boats, who often have to pull the boat ashore.
Advantages and disadvantages of the model
Like any technique, boat-engine It has its strengths and weaknesses, and its unquestionable advantages include its repairability, parts for which can be found in almost any boating store, and many of the units are interchangeable with other Soviet and Russian models.
Low fuel quality is another important argument for buying, and you can be sure that even imperfect gasoline at a remote refueling station won't cause instantaneous fuel system failure, and the simplicity of the design allows you to do the repairs yourself, with a basic set of tools.
The Hidden Benefits of Design
The engine uses a reciprocating-loop purging scheme that provides a more complete combustion of the mixture compared to the deflector engines of older models, which increases efficiency and reduces the formation of gas.
But the downsides are also not to be forgotten: noise and vibration levels at high speeds remain high. Volgar It's a working tool, not a comfortable cruiser, and it's also worth noting that there's no neutral gear in the classical sense on some early versions, which requires a little bit of habituation when maneuvering.
- 🛠️ High availability of spare parts and ease of maintenance.
- ⛽ Possibility of working on low-octane gasoline.
- 💰 Low cost of ownership and repair.
- 🔊 Increased noise level compared to modern analogues.
Owners also note high fuel consumption when driving actively, which is typical of old-school two-stroke engines, and if every liter of gasoline is important to you, you should consider this factor when planning long-distance walks.
Features of operation and break-in
The right break-in is the key to the long-term service of your engine, even though it's simple to design. boat-engine The new unit or engine after major repairs must be operated in a gentle mode.
The first 10 hours of motorsport are recommended to work at speeds not exceeding 50% of the maximum. Do not give full load, sharply open the throttle or work at idle.
☑️ Checklist of preparations for the first launch
The fuel mixture must be prepared immediately before refueling, and the use of old gasoline or a mixture that has stood for more than a month can lead to resin formation and coking of piston rings. It is critical to use special two-stroke oils designed for water cooling to avoid the formation of soot on the candle and in the exhaust window.
⚠️ Attention: Never keep a full-mix engine indoors, and gasoline vapors are heavier than air and can accumulate at low points, creating an explosive situation.
Check the spark plug regularly. Black colored carbon indicates a rich mixture, white indicates a poor one. The optimal color of the electrode is brick-brown. Timely adjustment of the carburetor will help avoid problems with starting and losing power.
Typical malfunctions and methods of their elimination
Owners may face a number of typical problems during operation, most often with the ignition or fuel supply system. Volgar not start, first of all, you should check the presence of a spark and the flow of fuel into the cylinder.
Often the cause of failure is a contaminated carburetor or leakproof crankshaft, suction of extraneous air leads to impoverishment of the mixture and overheating of the engine. Diagnostics It should be carried out in series, starting from the tank and ending with the cylinder.
Procedure for checking the ignition system:1. Unwrap the candle.
2. Put on the cap and press the candle skirt to the mass.
3. Pull the starter sharply.
4. to check for a powerful blue spark.
Cooling problems are usually caused by debris getting on the water intake or by the wear of the pump impeller. If you notice that there is no water coming from the control hole, immediately shut off the engine to avoid jamming the piston.
- 🔍 Checking the compression will help to assess the condition of the piston group.
- 💧 Washing the carburetor eliminates problems with idling.
- 🔧 Replacement of osteoils is required when smoke appears and power is lost.
To correct serious malfunctions, you may need to disassemble the engine, in which case it is recommended to use repair kits of gaskets and glands, and do not try to use sealants instead of gaskets in high-pressure units.
Comparison with analogues and final conclusions
In today's market boat-engine It competes mainly with Chinese and newer Russian engines, and compared to Chinese engines of the same power, the domestic unit benefits in maintainability and availability of parts in the outback, but it can be inferior in ergonomics and noise levels.
Compared to the more modern models, Volgar It looks archaic, but it's this archaic nature that makes it last, and for those who value the simplicity and the ability to fix the knee motor, it's the perfect choice.
As a motor for weekend walks or fishing in a nearby pond, this engine is fully justified in its investment. It is simple, understandable and predictable in operation.
The main conclusion: outboard motor Volgar is the choice of pragmatists who need reliable traction without unnecessary electronics and complex maintenance, ready to put up with noise for the sake of maintainability.
So in conclusion, this motor remains relevant for a certain segment of the user base, and if you want a machine for serious work or long journeys, maybe you should consider more powerful and modern options, but for the soul and simple fishing, it's a time-tested option.
Frequently Asked Questions (FAQ)
What is the best octane gasoline for the Volgar engine?
The AI-92 is the best choice. Although the design allows for the use of the A-76, modern low-grade gasoline is difficult to find, and its quality often leaves much to be desired. AI-95 is not recommended without ignition adjustments, as this can lead to overheating.
Which oil is best to add to the mixture?
It is recommended to use special two-stroke oils labeled TC-W3. They are designed for water-cooled engines and provide good lubrication, minimizing the formation of soak. The mixing ratio is usually 1:25 (40 ml of oil per 1 liter of gasoline) for a new engine and 1:30 for a break-in one.
Can this motor be used on PVC boats?
Yeah, boat-engine It is great for PVC boats from 3 meters in length, but its weight (about 26 kg) should be considered. For light inflaters, this can be noticeable when carrying, but on water this mass provides good stability and handling.
How often should I change the spark plug?
The candle's life depends on the quality of the mixture and operating conditions, and on average, it is recommended to replace every 50-100 hours or if there are signs of unstable operation, and preventive cleaning and clearance checks are required more often - every 10 hours of work.
