When choosing an outboard motor for a small vessel, one of the key parameters that fishermen and hunters pay attention to is the mass of the unit, which determines not only the ease of transportation, but also the overall carrying capacity of the swimmer. Wind 12The silk-powered boat produced at the Ulyanovsk Motor Plant has been a popular choice for decades due to its reliability and maintainability, but when planning to buy or upgrade a boat, you need to clearly understand how much load the transom will have to withstand and how much force it will take to carry the equipment.
Many PVC inflatable boat owners often wonder how critical the weight of this two-stroke engine will be when launched alone. The answer lies in a detailed study of the technical specifications and real-world operating conditions. Knowing the exact mass allows you to correctly calculate the differentiation of the vessel and avoid overloading the stern, which directly affects safety and handling on the water.
In this article, we will discuss in detail how much weight you weigh. Wind 12 In different trim levels, how weight affects performance and why it's so important for lightweight aluminum and inflatable boat owners, we're going to look at the design features that determine weight performance and compare them to today's models.
Technical specifications and engine mass
The official manufacturer's documentation provides clear information on the overall weight specifications of the unit. Wind 12 This is the standard 12 horsepower engine value of the period, and it's considered the average in its class, and it's important to understand that this is dry weight, which means that you don't have to take into account fuel, oil and attachments.
The design of the diewood and cylinder block is made of aluminum alloys, which allows you to reduce the total weight while maintaining the necessary strength. Despite the fact that modern imported models can be lighter, the domestic unit benefits from the massiveness of the units, which has a positive effect on vibration resistance. 26 kg It is the weight that one person can carry over short distances, although long-term transportation will require the use of a wheelbarrow or the help of a partner.
Impact of the year of release on weight
Engines of early years of production could have slight differences in weight due to the use of different alloys or the thickness of the crankcase walls, but the difference rarely exceeded 0.5-1 kg.
It is also worth considering the weight of the full tank if it is integrated or mounted directly on the motor, although this model is more often used outlet tank. refueling tank of 12 liters will add another 8.5 kg to the total weight, which must be considered when calculating the static stability of the boat.
Size and their impact on transportation
In addition to the net weight, the critical parameters are the dimensions that determine the convenience of laying the engine in the trunk of the car or the boat. Wind 12 It is compact compared to its more powerful counterparts, making it ideal for small rivers and lakes, and the length, width and height of the motor are optimized for transverses up to 450 mm wide.
When transported in a car, the weight of 26 kg becomes noticeable if you have to carry the motor with one hand while holding the other gear bag. The body size does not allow it to be conveniently covered for long distances without a special belt. Therefore, experienced boaters recommend buying or manufacturing a transport handle immediately if the regular design does not suit you.
Use a special belt for carrying outboard motors - this will reduce the load on the spine when transporting Wind 12 from the car to the water.
Below is a table with the basic dimensional data that will help you plan the engine placement:
| Parameter | Meaning | Note |
|---|---|---|
| Length | 830 mm | Without the hummel. |
| Width | 240 mm | Maximum width of lower unit |
| Height. | 1050 mm | From the lower unit slice to the top slice |
| Dry weight | 26 kg | Standard equipment |
Comparison of weight with competitors and peers
To objectively assess weight Wind 12It's important to think about it in the context of other engines of similar power. There are both domestic and foreign models on the market, and the difference in mass can be significant. Japanese and Chinese counterparts are often easier due to the use of more modern composite materials and thin-wall casting, but lose in maintainability.
For example, some models with a capacity of 9.9-10 hp from well-known brands can weigh about 25-27 kg, which puts them in the same row as our hero. Wind The two-stroke engine circuit is less weighted than four-strokes of similar power, where additional gas distribution mechanisms are present.
- 🚤 Wind 12 26 kg (classic, time-tested).
- 🚤 Yamaha 9.9 GMHS - about 27 kg (reliable, but expensive to maintain).
- 🚤 Tohatsu M9.8B 25.5 kg (easier but more difficult to repair)
- 🚤 Electric motor 36 lb - about 7 kg (motor) + 15 kg (battery).
When choosing between a used wind turbine and a new Chinese engine, weight and reliability are often the deciding factors: a heavy cast-iron crankshaft and steel gear gear gears add weight, but provide a long service life even in harsh conditions.
The impact of weight on the operation of the PVC boat
For owners of inflatable boats, the issue of the weight of the outboard motor is especially acute. Wind 12 It's great for boats that are 3.2 to 4.0 meters long, and when mounted on lighter inflaters, a weight of 26 kg may require additional balancing to keep the stern from getting too submerged, especially when sleeveing with one person on board.
⚠️ Note: When installing the Wind 12 on an inflatable boat less than 3 meters long, be sure to check the maximum permissible power and weight of the motor specified by the manufacturer of the craft to avoid damage to the transom.
However, because of its mass, the engine is good at quenching vibrations that are transmitted to the boat hull. Light motors often create more noise and tremors, which can tire with prolonged fishing. Heavy lower unit better holds the jet and is less affected by excitement, which makes the boat's run more predictable.
When you're operating alone, the weight of the motor becomes a critical parameter when you load it. You have to lift 26 kilograms over your head or drag it along the shore. Using a wheelbarrow to transport the motor to the water will make life much easier and save you the strength to fish. Don't ignore the ergonomics of lifting, so as not to damage your back.
Design features that determine the mass
Why? Wind 12 The engine design involves a float carburetor, a magdino with a flywheel and ignition coils, and a full gearbox with a reverse, all of which are made of metal, which is the main gain in mass.
Unlike modern motors, where many plastic casings and composite legs are, metal reigns supreme. It increases weight, but it provides phenomenal survivability. If you hit a stone with a lower unit, the probability of breaking it is minimal, whereas plastic can crack. Massive lower unit also acts as a keel, improving course stability.
☑️ Check before buying a used Window
The water pump and cooling shirt are also made of metal and add weight, but ensure efficient heat removal even when working full speed for long periods. Lightweight counterparts often warm faster, requiring periodic discharge of gas.
Transportation and Storage Tips
Given the weight of 26 kg, the right organization of transportation is the key to your safety and safety of equipment. Do not try to drag the engine behind a rample or lower unit unless they have special handles. The best way is to use regular mounting holes or special belts.
When stored in a garage or in a country house, it is recommended to hang the engine vertically to avoid deformation of the lower unit and leakage of oil residues. Vertical position also saves space. If you store the engine in a horizontal position, be sure to drain the fuel and oil so that they do not fall into the cylinders.
⚠️ Warning: Never leave the Wind 12 in a transport position (on its side) for a long time without draining technical fluids - this can lead to souring of piston rings.
For frequent transportation in the trunk of the car, you can make or buy a hard case with a hard bottom, which not only protects the paintwork, but also allows you to easily carry the engine by taking up the handles of the case, the weight is distributed evenly, and the dirt from the engine will not stain the interior of the car.
Frequently Asked Questions (FAQ)
Can you install Wind 12 on an inflatable transom boat?
Technically, it is possible, but it is not recommended. The engine weight of 26 kg, combined with vibration and load on the plane can lead to deformation of the inflatable transom or its separation. For such boats it is better to use engines up to 5 hp or choose models with a rigid hinged transom.
Will the weight increase if you add oil to the tank?
Yes, it does. The 12-liter wind tank holds 12 liters. The gasoline density is about 0.75 kg/l, the oil is about 0.9 kg/l. The full tank will add to the weight of the engine about 9-10 kg. In total, the engine will weigh about 35-36 kg in running order.
Does the wind have 12 electric starter and how does it affect weight?
The classic Wind 12 is equipped with only a manual starter. There were almost no modifications to the electric starter in mass production, since this would require the installation of a battery and a generator of increased power, which would significantly increase the weight and dimensions, disrupting the balance of the boat.
How hard is it to lift the 12th wind per transom?
For a person with moderate fitness, lifting 26 kg to a transom (usually 40-50 cm from the ground) is quite real. However, doing this regularly without a stand or assistant is harmful to the back.
