Legendary Kazan 5M2 It is considered one of the most popular and recognizable boats in the history of domestic shipbuilding, and this aluminum boat, which rolled off the assembly line of the Kazan Aviation Plant, has become a benchmark for reliability and accessibility for thousands of anglers and tourists. Despite the fact that mass production has been discontinued, interest in this model is not fading, and in the secondary market it is in stable demand due to its maintainability and simplicity of design.
Many boaters choose this model because of its versatility, which is great for both quiet fishing in reservoirs and for overnight hikes on board. However, when buying a used one or planning an upgrade, it is crucial to know the exact details of the process. specificationto choose the right engine and not violate safety requirements.
In this article, we will analyze in detail all the parameters of the body, load capacity, permissible engine power and other nuances that must be taken into account by the owner. Kazan 5M2Understanding this data will help you avoid fatal errors in operation and ensure a long life of your boat.
History of creation and design features
Modifications Kazan 5M2 The company was created as a response to users who lacked the power and comfort of the base five, and the plant's engineers made a series of design changes to improve seaworthiness and safety, with the main difference being the ability to install more powerful outboard motors, which required the transom to be strengthened and the geometry of the body changed.
The hull is made of aluminum-manganese alloy AMg5M, which is highly corrosion-resistant and ductile. The hull is riveted, which provides high strength seams, but requires periodic sealing checks. It is riveted design that is often the subject of controversy: some praise it for reliability, others criticize it for the complexity of repair.
Why the rivet?
Range joints are less prone to fatigue cracks when vibrating than welds on thin metal, however, they require regular stretching and replacement of seals.
An important feature of the model is the presence of boulder Without these elements, the boat would tend to be heavily rolled, especially when sliding or when moving passengers, and the buoys also serve as additional volume, increasing unsinkability.
Overall dimensions and weight parameters
When choosing a place for storage or transportation on a trailer, it is critical to know the exact dimensions. Kazan 5M2The length of the body along the waterline and the full length allow you to feel confident on the wave, but create restrictions when transporting on the roof of a passenger car.
The weight of the boat in running order is one of the key factors influencing the choice of trailer and the power of the tractor car. Aluminum alloy allows you to keep the weight within reasonable limits, but the presence of boules and reinforced transom adds its pounds to the total figure.
| Parameter | Meaning |
|---|---|
| Longest length | 4600 mm |
| largest width | 1650 mm |
| Height on midship | 650 mm |
| Mass of the hull with equipment | 150 kg |
| Load capacity | 400 kg |
Please note that the specified 150 kg of body weight can vary depending on the year of manufacture and configuration of a particular instance. The presence of hazelnuts, windscreen and built-in tanks can increase the actual weight.
The actual load capacity of 400 kg includes the weight of passengers, motor, fuel and equipment, so it is important not to exceed this limit for safety.
Capacity and passenger capacity
Officially. Kazan 5M2 It's classified as a five-seater boat, which means it's designed to carry five people of average build, but in practice, it's possible for three or four adults to be comfortable, especially if you're going to go on a long trip with lots of equipment.
- 🛶 The nose can: It is designed for a single passenger, but is often used to accommodate fishing boxes or navigation equipment.
- 🛶 Middle seats: Two places in the central part, which are the most protected from splashes and wind.
- 🛶 The feed bank: It is designed for two, but when installing a powerful motor, the passenger's legroom is often limited to lower unit.
The weight distribution of the cockpit is critical to handling. Shifting passengers to one side can lead to a dangerous roll that the buoys can't always compensate for.
Engine installation and engine power
One of the most discussed issues is the permissible power of the outboard motor. The manufacturer has indicated different values at different times, but the most common and safe is the restriction of the power of the outboard motor. 25-30 hp. Installation of more powerful engines requires serious alteration of the transom and carries risks for the integrity of the housing.
When choosing a motor, you should take into account not only horsepower, but also the weight of the engine. Kazan 5M2 sensitive to differentiation: too heavy motor on a short transom can lead to burrowing of the nose or, conversely, to nose uplift and loss of controllability.
⚠️ Attention: Operating a boat with an engine of more than 30 hp without proper registration and categorization in the GIMS can lead to a fine and a ban on operation.
The optimal choice for this model are two-stroke or four-stroke engines in the range of 15-25 hp They provide access to planing with full load and economical fuel consumption. Engines with a capacity of 5-10 hp will only allow displacement mode, which will significantly increase fuel consumption per kilometer of travel.
Driving and seaworthiness
Thanks to the sharp-nosed shape of the body and the zygomatic splash-blowers, Kazan 5M2 It keeps the wave steady to 0.75 meters, and it allows you to go out into the waters of large rivers and reservoirs, where wind turbulence can be significant, but it's worth remembering that this is not a sea boat, and it is not recommended to go out into the open sea.
The boat is stable in planing, but requires careful steering. The aluminum body is light enough that when hit by a collision wave, you can hit the water, which is transmitted to the seats. The comfort of swimming depends on the ability of the steering wheel to choose the trajectory of movement.
To reduce the impact load on the body and increase comfort, it is recommended to use inflatable tubes or install shock absorbing seats with suspension.
The maneuverability of the vessel is estimated as average. The circulation radius depends on the power of the motor and the position of the lower unit. On small strokes, in the absence of an electric motor or a bow thruster, the sailing of the high side can be difficult to control in strong lateral winds.
Service and typical problems
Despite its reliability, the age of most boats of this model dictates its operating conditions. Kazan Electrochemical corrosion, which occurs when dissimilar metals come into contact in salty or contaminated water, and also leaks through rivets and leaks in the seams.
- 🔧 Rivet check: Examine the rows of rivets annually, especially in the nose and along the cheekbones, for oxidation and oxidation.
- 🔧 Transnant protection: If you are using a long leg motor, make sure that the transom height is standard (380-400 mm), otherwise water can be thrown into the cockpit.
- 🔧 Coloring: timely update of anti-corrosion coating prolongs the life of the case for decades.
Repairing holes or cracks is best done by argon welding using a similar brand of additive material, and the use of epoxy mixtures or cold welding is only permissible as a temporary measure for emergency return to the base.
☑️ Kazanka's Seasonal TO
⚠️ Attention: When welding aluminum less than 2 mm thick (bottom of the boat), burn the metal. Trust this work only to specialists with experience with thin-walled structures.
Frequently Asked Questions (FAQ)
Can I put a 40 hp engine on Kazanka 5M2?
Technically, the hull can withstand a short-term load, but the manufacturer did not recommend power above 30 hp Installation 40 hp requires strengthening the transom, changing the alignment and, most likely, will lead to problems with registration in the GIMS. This is risky for the safety of the crew.
What is the real speed of a boat with a 20 hp engine?
With one driver and a full tank. Kazan 5M2 with the engine 20 hp develops a speed of about 30-35 km / h At full load (4 people) the speed drops to 20-25 km / h, and the output to planing can be difficult.
Do I need to register Kazanka 5M2 in GIMS?
The hull weighs 150 kg plus the weight of the motor (even the lightest) exceeds the 200 kg threshold, after which registration of a small craft not intended for commercial purposes is mandatory.
Where can I find plans for repairing boules?
Official drawings are often found in old operating manuals or in specialized water motor forums. When making new boules, it is important to keep their volume and cross-sectional shape, as they are a bearing element of stability.
