Legendary Kazan 5M2 The model, which is based on the popular Kazanka 5, has become a popular hit due to its strength, maintainability and affordability, and many holiday owners and fishing enthusiasts still look for this option to provide themselves with reliable transport for moving through water bodies.
However, despite the mass nature, the technical nuances of this vessel often raise questions among beginners. Aluminum alloyThe slate that is made of the body requires a special approach to operation, and the design of the transom imposes restrictions on the choice of engine. In this article, we will discuss all the parameters in detail so that you can make an informed decision about buying or upgrading.
It is worth noting that most surviving specimens are decades old, so the condition of a particular specimen is crucial. technicality This will help to avoid problems on the water and prolong the life of this veteran of domestic shipbuilding.
History of creation and design features
Development Kazan 5M2 The new model was conducted by Kazan Aviation Plant named after Gorbunov in response to the requests of the population for a more spacious and safe boat, unlike its predecessor, the new model received an elongated hull and, most importantly, reinforced sides, which significantly improved stability and safety when riding the wave.
The key difference was the design of the boards, which were made in the form of boulder This engineering idea has allowed not only to increase the useful area of the cockpit, but also to provide additional buoyancy, and even if the water is completely filled with internal volume, the boat will not go to the bottom, staying afloat due to the air cushion in the bules.
⚠️ Warning: When buying a used boat, be sure to check the tightness of the boules. The presence of water inside them indicates a violation of the integrity of the welds or corrosion, which requires immediate repair.
The hull is made of aluminum-magnesium alloy AMG5M, which provides high corrosion resistance. However, despite the strength specifications of the material, thin sheets of skin (especially in the early series) can suffer mechanical damage when hitting stones or logs. The design provides a removable windshield and the ability to install an awning, making it suitable for multi-day travel.
Basic dimensions and weight parameters
Overall dimensions Kazan 5M2 The hull is 4500 mm long, providing excellent cruising and allows you to feel confident on the wave up to 0.5 meters. Midwive width is 1600 mm, which is a compromise between stability and ease of transportation on the roof of a passenger car.
The weight of an empty boat with equipment (without a motor) is about 150 kg. This value can vary depending on the configuration, the availability of deck and installed equipment. Load capacity The vessel allows you to take on board up to 400 kg of payload, including passengers, equipment and engine.
For ease of transportation and storage, the windshield can be dismantled and seats removed. However, the body itself is monolithic and its transportation requires a reliable trailer or upper trunk with appropriate carrying capacity.
| Parameter | Meaning | Note |
|---|---|---|
| Full length | 4,500 mm | Including the transom. |
| maximum width | 1600 mm | In cheekbones |
| Height of board | 720 mm | Midle. |
| Hull mass | 150 kg | No motor. |
| Load capacity | 400 kg | 5 people |
When transporting on the roof of the car, be sure to use soft pads under the body to avoid dents on the bottom from the trunk crosses.
Navigability and sustainability
Resilience Kazan 5M2 It's not only the width of the hull, but also the shape of the bottom with the cheekbones, and the boat is very strong and has good germination, but because of the relatively flat bottom in the bow, the oncoming wave can be hard hit, so the speed should be adjusted depending on the conditions.
An important aspect is floatabilityBecause of its sealed boules, the boat has enough buoyancy to hold a fully watered crewed boat, a safety requirement that was introduced after analyzing the accident rate of earlier models, but it is not necessary to rely on the boules alone - life jackets are mandatory.
Wind resistance allows the boat to be used in open areas of lakes and reservoirs, while the high-side sailing requires careful management in strong side winds, especially if there is only one person on board.
⚠️ Note: Do not exceed the permissible wave height (0.5 m) and distance from the shore (3 km) when entering open water.
Power plant and engine requirements
Selection of engine Kazan 5M2 The boat's traversal is designed to accommodate outboard motors up to 12 hp (in some versions up to 15 hp, but this is a risk), and installing a more powerful motor can lead to deformation of the transom and loss of stability at high speeds.
The best choice is considered to be motors. Whirlwind-12, Whirlwind-15 or modern imported analogues in this capacity range, for example, Yamaha 9.9 or Tohatsu 9.8With a 10-12 hp engine, the boat reaches a speed of about 30-35 km / h with a single driver, which is quite enough for fishing and cruising.
When installing the motor, it is important to choose the right one. lower unit The engine lifting too high will lead to cavitation and loss of traction, and too low will lead to increased water resistance, and the adjustment must be done experimentally on water.
- 🚤 Optimal power: 8-12 hp for economical running.
- 🚤 Maximum power: 15 hp (for experienced drivers and short transoms only).
- 🚤 Engine type: Two-stroke or four-stroke, long leg.
- 🚤 Recommendation: The use of remote gas control increases comfort and safety.
Exceeding the recommended engine power of more than 15 hp on Kazanka 5M2 is strictly not recommended because of the risk of loss of longitudinal stability (tilting) and the destruction of the transom.
Internal equipment and comfort
Interior Kazan 5M2 It's spartan, but functional. The nose has a trunk that's sealed, which is ideal for storing things that aren't afraid of moisture, and the floor of the cockpit is usually covered with wooden or plywood sleighs that protect the aluminum bottom from mechanical damage and improve thermal insulation.
The seats are made in the form of hard cans, often with soft linings. Some trim levels provided a folding windscreen, which greatly facilitates management in windy weather and protects against splashes. The ability to install an awning makes it possible to use a boat in rainy weather.
For fishermen, an important element is the possibility of installation. rod-holder The design of the boat makes it easy to upgrade the interior to suit your needs, installing additional hazelnuts or tables.
☑️ Checking the completeness before buying
Typical problems and their solution
Despite the reliability, age takes its toll. corrosion Aluminum is susceptible to electrochemical corrosion, especially if the boat was in salt water or in contact with other metals (for example, steel bolts).
Another problem is to leak through rivets and bolt joints, and over time, the sealing pads will dry up and water will start to seep in, and the solution is one: complete bulkheading, replacing the fasteners with stainless and using quality equipment. sealant for boats.
Mechanical damage to the bottom is also not uncommon, dents can be repaired, but cracks require professional argon welding, and it is important not to ignore even minor damage, as vibration on the water contributes to their growth.
⚠️ Warning: Never use steel fasteners (bolts, nuts) to repair an aluminum case without insulation. Contact of dissimilar metals in water causes instant galvanic corrosion.
The secret of longevity Kazanka
Experienced owners recommend that the boat be completely removed from the trailer, washed with fresh water and thoroughly dried every year before being put into winter storage. Pay special attention to the places where the aluminum sheets junction. Treatment with special anti-corrosion compounds (for example, based on zinc) every 2-3 years significantly prolongs the life of the hull.
FAQ: Frequently asked questions
Can I put a 20 hp engine on Kazanka 5M2?
Technically, it's possible, but it's not safe. The Tran can't handle the high-speed load, and the stability of the plane boat with this engine is critically low, and the risk of tipping over or burrowing your nose in the wave is very high.
What is the maximum weight of Kazanka 5M2?
Passenger carrying capacity is 400 kg, which includes the weight of passengers, motor, fuel and equipment, and exceeding this limit will lead to lower height above the water and loss of safety.
What is the difference between Kazan 5M and 5M2?
The main difference is the design of the sides: the 5M2 had bulges (closed compartments), which gave it extra buoyancy and rigidity. The regular 5M had a simpler side, without such pronounced boules, which made it less stable.
Do I need to register Kazanka 5M2 in GIMS?
Yes, if the weight of the boat with the installed engine exceeds 200 kg or the engine power is more than 8 kW (about 10.8 hp). Since Kazanka 5M2 weighs about 150 kg, then when installing the engine over 5-6 hp registration is mandatory.
