Choosing a reliable hanger-engine For a small PVC boat or light aluminum boat, it often turns into a search for a balance between price and quality. squidThese are marketed as affordable alternatives to expensive Japanese and European models, and many aquatic motorists view them as a workhorse for fishing, hunting or simple walks in the reservoir without requiring the technology to go too fast.
However, the purchase of such equipment is always accompanied by a lot of questions about the real life of the piston group, the quality of the assembly and the availability of spare parts. Two-stroke circuitThe stereo, used in most models of this lineup, requires strict adherence to the proportions of the mixture and the correct running procedure, otherwise the engine may fail well before the warranty period expires.
In this article, we will discuss in detail the technical features, common modifications and real-world experience gained by users over recent seasons.
Technical features and model range
The manufacturer's range of products covers a wide range of needs, from compact models for inflatable boats to more powerful versions for lightweight hulls. two-stroke The lack of a complex lubrication system (oil mixed with gasoline) makes the unit easier and easier to repair, although it imposes restrictions on environmental friendliness and noise.
The most popular models are from 2 to 9.8 horsepower. Low-power engines, such as 2.6 hp, often have an integrated tank and serve as an ideal backup option or main propulsion for single fishing. More powerful versions, such as 9.8 hp, can already be equipped with a remote fuel tank and system. electronic ignition (CDI) which significantly improves the stability of work at different turns.
⚠️ Note: When choosing a model, pay attention to the type of lower unit. The shortened leg (S) is for inflatable boats, and the long leg (L) is for translucent boats. Installing a short motor on a high transom will lead to cavitation and overheating.
The gearshift system is an important aspect, and most of the time, a manual gearbox with three positions is used: neutral, front and reverse. The propeller It usually has standard specifications that make it easy to choose a replacement or tuned version with a modified pitch to achieve better speed performance.
Procedure for proper engine break-in
The first hours of work are critical to the formation of a resource piston-groupIgnoring the rules of running is the main reason for early bullies and loss of compression in budget engines. The process of grinding parts takes time and patience, but ensures that the engine is not in the process of being replaced. squid It will last for many years without major repairs.
Fuel mixing must be strictly in the ratio of 1:25 (40 ml of oil per 1 liter of gasoline) for the first tanks, even if the instructions for subsequent use are specified in the ratio of 1:50. TC-W3 Saving on oil or using waste liquids is not allowed.
☑️ Checklist for engine break-in
The first two tanks should be operated in a gentle manner. It is not recommended to develop full power or run at maximum speed. The engine should warm up evenly, without sudden load surges. After the first 10 liters of the mixture are produced, the proportion can be changed to a standard 1:50, but sharp gas jerks are still undesirable.
Why is the new engine smoking?
The new two-stroke engine always smokes more during the break-in period, it burns the conservation lubricant and the excess oil needed to grind the rings. If the smoke is white or grayish and there is no smell of burning, it is normal. Black smoke indicates an over-enriched mixture or problems with the carburetor, and bluish smoke with the smell of scorching metal is a sign of overheating or improper proportion of oil.
It's important to monitor the body temperature, and if the hand can barely touch the lower unit around the cylinders, then the engine is running in a tight mode and the load should be reduced. Cooling system should consistently eject the stream of water; the absence of a "spit" indicates a malfunction of the water pump or clogging of the channels.
Comparison of specifications of popular models
It is important for a potential buyer to understand the difference between modifications, since the appearance may be similar, but the internal filling and purpose are different. Below is a comparative table of the main parameters that are most interested in water engines when choosing a particular model.
| Model | Power (hp) | Workload (cm3) | Weight (kg) | Type of management |
|---|---|---|---|---|
| KM-2.6 | 2.6 | 49 | 9.5 | rumble |
| KM-5.0 | 5.0 | 90 | 19.0 | rumble |
| KM-9.8 | 9.8 | 169 | 26.0 | Rumpling/Remote |
| KM-15.0 | 15.0 | 246 | 34.0 | Rumpling/Remote |
Model KM-9.8 It is often the middle ground for owners of boats with a length of 3-4 meters, it is able to bring a loaded boat to the plane, which is critical for comfortable movement on large water. More powerful versions, such as 15 hp, already require a stronger transom and often equipped with a separate battery recharging system, which allows the use of sonars and navigators without an additional power source.
When comparing, you should consider not only the declared power, but also the torque at low revs. It is this parameter that determines how easily a boat will exit the displacement mode. carburetor In more powerful models, it usually has an accelerator pump, which improves the responsiveness of the engine when the throttle is opened sharply.
Maintenance and typical faults
Regular maintenance is the key to the long life of any machine. squid The spark plug should be given special attention to the cleanliness of the fuel system. Turning a candle and visually examining its coar can tell more about the engine than any external signs. Brown tan indicates normal operation, black indicates a rich mixture, and white indicates a poor one.
One of the common problems is clogging of the carburetor's jelly jellies, especially if the motor is stored for a long time with residues of fuel in the float chamber. Gasoline evaporates, leaving resinous deposits that block the channels. Fuel filter rough cleaning, installed in the tank or in the rupture of the highway, helps to detain large debris, but it does not save from small fractions.
⚠️ Warning: Never store a full tank of gasoline during the winter, lose its properties, oxidize and form a sediment that clogs the carburetor, drain the residues or use fuel stabilizers.
It is also important to periodically lubricate the points of rotation of the tiller and the gearshift mechanism. The water entering the gearbox is checked visually: if the oil in the gearbox has acquired a milky shade, then the sealing of the ossels is broken and their replacement is required. Operating the motor with water in the gearbox will lead to rapid destruction of the gears.
Lubricate lower unit with silicone grease after each exit, which will prevent shells from fouling and oxidizing aluminum surfaces in salt water.
Choosing oil and preparing a fuel mixture
The quality of the lubricant directly affects the resource crank-and-wheelerFor two-stroke outboard motors, oils intended for chainsaws or motorblocks are categorically not suitable, since they have a different combustion temperature and ash content. TC-W3.
It's better to make the mixture in a separate, clean canister, rather than pouring oil and gasoline directly into the engine tank, which ensures that the components are evenly mixed, first pouring half the required volume of gasoline, then adding the entire volume of oil, the mixture is shaken, and only then adding the rest of the gasoline.
Use of use leaded or fuel with an octane number below AI-92 (unless otherwise specified in the instructions) can lead to detonation and burnout of the piston. squid The fuel is designed to work with quality AI-92 or AI-95. The use of fuel with an octane number of 80 (A-76) is unacceptable.
The right mix proportion and quality TC-W3 oil are more important than the brand of the engine itself, saving 100 rubles per liter of oil can lead to repairs at half the price of a new engine.
It is recommended to store the finished fuel mixture for no more than one month. Over time, the oil begins to precipitate and loses its lubricating properties, which makes the mixture aggressive for rubber carburetor seals.
Real reviews and experience of operation
And by looking at the feedback from owners, there are a few consistent trends: motors are often praised for their maintainability and availability, and they're structurally very much like the time-tested Japanese designs, so you can find them. piston-group Or carburetor is not difficult even in remote regions.
The most common complaints are the quality of aluminum casting and assembly, with bumper-mounted backlashes or imperfect fitting of casings, but for many anglers, this is secondary to the main function of pulling a boat, and motors have proven themselves to be “unkillable” provided that the glands and candles are replaced in a timely manner.
There is also a high fuel consumption of some versions compared to the four-stroke counterparts, which is a inherent feature of the two-stroke scheme. However, the ease of starting even in cold weather and the ease of running compensate for this disadvantage for many outdoor enthusiasts.
⚠️ Warning: When buying a motor with your hands, be sure to check the compression. A value below 6-7 atmospheres for a low-power two-stroke indicates serious wear and tear of the CNG and the need for rapid repair.
Overall, the brand squid It has become a niche for those who are not willing to pay more for famous brands, but want to get a working tool. With proper operation and timely maintenance, these engines can go away for several seasons, delighting the owner with confident traction and reliability.
Can I use the Squid motor in salt water?
Yes, you can, but with a mandatory wash with fresh water after each exit. Aluminum alloys are subject to corrosion in a salty environment. You need to lubricate all external metal surfaces with anti-corrosion compounds and monitor the state of anodic protection (if it is provided by the design of a particular model).
Which gasoline is better to pour: AI-92 or AI-95?
Most models squid The AI-95 is allowed but does not produce a significant increase in power, and in some cases can lead to later ignition if the carburetor is not configured accordingly.
Why does the engine stop at high speeds?
Most often, this indicates a starvation of the engine, the reasons: the fuel filter is clogged, the net in the tank is clogged, the valve in the tank lid is faulty (a vacuum is created), or the carburetor is not configured correctly (a too poor mixture at high revs).
