Choosing a light boat attachment engine is always about balancing power, weight and price, and the small mechanization segment has been dominated by a model known as the “Small Mechanization” for many years. Hey, 22.This unit has become a kind of legend for owners of inflatable PVC boats and small wooden timbers, offering an affordable alternative to rowing.
Many boaters are still looking for information about this model, trying to understand its real capabilities. Hey, 22. It is a two-stroke engine that was designed to meet the specifics of Russian water bodies and operating conditions, and it is not without its drawbacks, but its maintainability and simplicity of design make it relevant even today.
In this article, we will analyze the specifications, analyze the actual fuel consumption and gather the experience of owners who have been using this engine for years. Understanding the nuances of the carburetor system and running it correctly will help you avoid common mistakes.
General concept and history of the model
Engine. Hey, 22. It is the direct successor to the Soviet school of motor engineering, which is focused on mass and maintainability, and is structurally a two-stroke single-cylinder unit with forced air cooling, and it was not chosen by chance: the lack of a water pump and a complex cooling system significantly reduces weight and simplifies maintenance.
The main feature of the model is its versatility: the engine is easily installed on transverses of various thicknesses, and the swivel bracket allows you to control the boat's turn of the engine itself. Air cooling makes it virtually indestructible in shallow water or algae areas where the screw motor could overheat due to the intake of dirty water.
But it's worth noting that the engine design involves a mixture of gasoline and oil, a classic two-stroke design that requires the owner to be careful about the fuel mix, and that the wrong proportions can cause the piston group to fail quickly.
⚠️ Warning: Never run an engine on pure gasoline without adding oil. This is guaranteed to lead to bullies in the cylinder and a piston wedge within minutes of operation.
When preparing the mixture, use only special two-stroke oils labeled TC-W3. Motor oils for four-stroke engines or old waste oil are categorically not suitable.
Technical specifications and design features
To understand whether this unit is suitable for you, you need to carefully study its data-sheet figures. Hey, 22. It is positioned as a motor for light boats up to 3.5-4 meters long. Its power of 2.2 horsepower (hence the figure in the name) allows you to reach a speed of about 10-12 km / h on an inflatable boat with one person on board.
The design of the engine is as simple as possible. There's no electronic ignition in the modern sense, it uses a magdino and a breaker. The carburetor also has a simple device that allows it to be repaired in the field with a minimum set of tools. The engine weighs about 9.5 kg, making it convenient to carry in the trunk of a passenger car.
The important element is the lower unit and gearbox, and unlike many modern ones, it uses a robust, albeit noisy, gear gear gear, and it provides good torque at low revs, which is important for planing or counter-current.
Secret of marking
The number 22 in the model name comes from the old system of designating power in "horsepower" according to the Soviet standard, which was slightly different from modern metrics.
Below is a table of the main technical parameters that will help you compare Hey, 22. with competitors:
| Parameter | Meaning |
|---|---|
| Type of engine | two-stroke, 1 cylinder |
| Power | 2.2 hp (1.6 kW) |
| Workload | 52 cu.cm |
| Cooling system | Air, forced |
| Weight (no fuel) | 9.5 kg |
Fuel consumption and economy
One of the most common questions prospective buyers ask is about the appetite of this engine: Two-stroke engines are traditionally considered more voracious than four-stroke counterparts, but in the low-power class, the difference is not as dramatic as it seems.
The manufacturer's declared fuel consumption is about 1.1-1.3 liters per hour when operating at full power. However, in practice, when driving in economical mode (about 70-80% of maximum revolutions), you can achieve a figure of 0.8-0.9 liters per hour, this volume is enough for 4-5 hours of active running with a tank of 4-5 liters.
The economy depends on the quality of the mixture and the configuration of the carburetor. If the engine is "trotting" or smoke, the consumption will inevitably increase. Hey, 22. It works smoothly, with a minimum amount of exhaust, which indicates a complete combustion of the fuel mixture.
Consider that low-quality gasoline with a low octane number (below AI-92) can lead to detonation, which not only increases consumption, but also destroys the piston group, so saving on fuel in this case is a false saving.
The process of running and first start
The success of your engine depends on 90% of the first phase of operation. break-in It's the process of rubbing parts together, and skipping this step or breaking the rules of it often causes the motor to fail quickly.
The breaking in process Hey, 22. It has to be done in several stages. First, the engine is started at idle speed in a water tank (barrel) for 5-10 minutes, this is necessary to check the ignition system and there is no extraneous noise, then the stage of operation under load, but not at full power.
☑️ Checklist of proper breaking in
During the first hours of operation (usually the first 5-10 hours of motorized operation), it is not recommended to open the throttle more than 50-60%. The engine should operate in a gentle mode, alternating loads. It is also important to monitor the temperature of the cylinder head - it should not be too hot to the touch (short-term touch, but not holding the hand is allowed).
⚠️ Warning: Do not run dry or at full power. The sharp heating of the unwound piston will cause it to expand and jam in the cylinder.
Maintenance and typical faults
Despite the simplicity, Hey, 22. Maintenance is about cleaning the carburetor, replacing spark plugs and lubricating bearings. Because the motor operates in an aggressive environment (water, salt, dirt), the corrosion resistance of the materials plays an important role.
One of the common problems is clogging of the carburetor's jellyplates, which is due to poor-quality fuel or prolonged downtime with the remaining gasoline in the tank, and before each wintering, it is recommended to produce all the gasoline from the carburetor, allowing the engine to stall itself.
Owners also experience a leaky crankshaft coil, which is a sign of a malfunction that is sucking air, which leads to impoverishment and overheating. Diagnostics is carried out by spraying the joints of the crankcase of the working WD-40 engine: if the revolutions change, then the tightness is broken.
List of typical problems and methods of their solution:
- 🔥 The engine is dead on the idle: You need to clean the blank jacket of the carburetor or adjust the screw of the quality of the mixture.
- 💨 Vibration: check the condition of the lower unit and the motor attachment to the transom, it may be necessary to balance the screw.
- 💧 Water hitting the gearbox: replace the glands and check the sealing rings, lubricate with a consistent lubricant.
Regular replacement of fuel filters and the use of fuel stabilizers during long-term storage prolong the life of the carburetor at times.
Real feedback from owners and experience of operation
User opinion is the best indicator of reliability of the equipment, and by analyzing many forums and reports, we can identify the general trends in attitudes towards the model. Hey, 22.Most owners praise the engine for its “unkillability” and ability to start even after long downtime.
But there are complaints, and users complain about high noise and vibration levels, and a two-stroke engine without a resonant muffler (a simple muffler-expander) creates a distinctive ringing sound that can be tiring during long fishing.
Another thing is weight, and while 9.5 kg may seem a bit small, with constant socks and a boat and a tank, it's tangible, and yet for summer residents and those who like quiet fishing in quiet backwaters, this engine remains one of the best offers on the market.
The reviews also highlight the importance of properly configuring the ignition, with many traction problems solved by simply adjusting the gap between the magdino and the coil or replacing the contact group with electronic ignition from third-party manufacturers.
How to increase the engine life of the Hi 22?
To increase the resource, experienced mechanics recommend: use high-quality synthetic oil for two-stroke engines, add additives to the fuel that clean the combustion chamber, and regularly lubricate the crankshaft bearing through the oil (if the design prejudgments) or disassembling the crankcase once a season.
Can I put Hello 22 on a boat 5 meters long?
Technically, you can run the boat, but it won't be effective. For a five-meter boat (especially with a keel and a hard bottom), 2.2 hp will not be enough to get on plane even with one person. The engine will run at its limit, which will lead to rapid wear.
Which screw is better to choose for shallow water?
For shallow water and overgrown areas, screws with a larger pitch and a smaller diameter, or special “mud” screws with an increased gap between the blades, are best suited, which will reduce the risk of winding the grass and hitting the bottom.
Why does the engine smoke blue smoke?
Blue smoke is a sign of oil burning. If the smoke is moderate when warmed up, it's normal. If it smokes constantly and strongly, then the proportion of the mixture is broken (too much oil) or the piston rings are worn out, and the oil enters the combustion chamber from the crankcase.
Do I need to hand-wash the piston before assembly?
No, modern spare parts (pistons and cylinders) have the necessary tolerances and do not require manual laundry with abrasives; on the contrary, it can spoil the geometry of parts. Laundry occurs naturally during proper break-in.
