Aluminum floating vehicles manufactured by Kazan Aviation Plant named after Gorky have remained the benchmark of reliability and availability on domestic water bodies for more than half a century. Kazanka boat with an engine It is a classic bundle, tested by generations of fishermen and tourists, which, if properly modernized, is able to compete with modern fiberglass and PVC counterparts. outboard It is capable of unlocking the potential of this metal horse without disrupting the boat’s balance and safety.
The modern approach to the operation of these boats involves not just hanging the engine on a transom, but a comprehensive revision of the hull to improve seaworthiness and comfort. In this article, we will discuss in detail the nuances of the power selection plant, the features of the installation cross-plate And the secrets of tuning that turn a simple Kazanka into a full-fledged pleasure boat, you will learn why older models require special attention to differentiation and how to avoid common mistakes when completing.
It is important to understand that the factory specifications laid down in the 60-70s do not always meet the requirements of modern navigation and high-speed traffic. Aluminum alloyThe hull, which is made of the hull, has its own specifications of behavior on the wave, which must be compensated by the correct selection of equipment. Competent bundle "body-motor" allows you to achieve a cruising speed of 30-40 km / h, which makes the trip not only pleasant, but also fast.
Choosing the optimal motor power for different modifications
The first thing that the owner of the "iron" boat faces is the power limit indicated in the product's passport. Kazan (project 180) the standard power is usually limited to 8-10 hp, which allows you to reach a speed of about 25-30 km / h. However, enthusiasts often take the risk and install more powerful units, forgetting that stability For models with an M or MD index, the allowable power is already higher and can reach 15-20 hp, which is the middle ground for a family holiday.
More modern versions, such as Kazan 5 or 5mm, structurally designed for the installation of engines with a capacity of up to 30-35 hp Installation of a 40-horsepower engine on such a boat is possible, but requires mandatory refinement of the transom part and an understanding of the risks. engine begins to work in a suboptimal mode, and the boat can go into a “cobro” or burrow its nose in the wave with improper weighting.
When choosing between two-stroke and four-stroke engines, the weight of the power plant should be considered. For light aluminum housings, four-strokes are often a bit heavy, shifting the center of gravity and impairing driving performance. yamaha or tohatsu 15-20 hp often become the perfect compromise, providing the necessary traction without a critical preponderance of the feed.
⚠️ Warning: Installing a motor with a power exceeding data-sheet figures by more than 30% can lead to irreversible deformation of the transom and loss of warranty (if it is still relevant), and also poses a real threat to the safety of the crew on the wave.
When choosing an engine, you should also pay attention to the length of the daydvut. fairway In low depths, a short motor leg will be preferred, even at the expense of maximum speed.
Refining the transom and installing a submotor board
The weakness of most older aluminum boats is the regular transom, which often can not withstand the vibrations of a powerful engine and suspension weight. Installing a moisture-resistant plywood modular board (FSF grades at least 20 mm thick) is the first step to reliable operation. keel-line boats.
The installation process requires care: the board must fit snugly to the transom throughout the area, without gaps where water could accumulate. Mounting is carried out through the boat hull on reinforced bolts with wide washers, necessarily using the vibration-insulating This reduces the vibration transmission to the aluminum body, preventing cracks in the welding sites.
☑️ Testing transence readiness
It is important to set the angle of inclination of the motor board correctly. If the motor is too upward or, conversely, too deep, this will lead to cavitation of the propeller or, conversely, to "choking" of the engine. The optimal angle is selected experimentally, but the starting point is considered a position at which the anti-cavitation plate of the motor is at the same level with the conditional continuation of the bottom.
Do not forget about the protection of aluminum, the contact points of wood and metal, as well as the points of drilling must be carefully treated with epoxy soil or special mastics to prevent electrochemicalIn salt water or water with high mineralization, this process is especially rapid, destroying the structure from the inside.
Tuning of the body: increasing comfort and seaworthiness
The standard Kazanka is famous for its "stiffness" of the course and low landing, which even at a small wave the crew risks getting blows by the sides against the water. bulge Not only does this increase stability, but it also adds useful volume, allowing more equipment or passengers to be carried on board.
Internally, it also requires attention. Stiff cans are inconvenient for long transitions, so they are often replaced with soft seats with storage drawers inside, which allows you to optimize space and remove unnecessary things from under your feet, which is especially important when managing. pulp Or remote traction.
The secrets of noise insulation
To reduce engine noise and water splashing, many owners paste the interior of the sides and bottoms with vibration-insulating materials (such as Vibroplast) and a layer of noise insulation (Splen), which not only makes the trip quieter, but also creates an additional thermos, keeping the boat warm in cold weather or cool in the heat.
Storage facilities are another important aspect of tuning: the installation of sealed handbags in the nose allows you to store dry things, tools and equipment. navigational The equipment is safe even if the boat is flooded with a wave, and the tightness of such boxes is checked in advance using sealing bands around the perimeter of the lid.
To improve the performance of the nose boats often install zygomatic keels or additional redans, which help the boat to go up to the planing faster and improve the stability of the course, especially in lateral winds. However, any modification of the contours should be carried out with the expectation that not to disturb the centering and not make the boat too thin.
Comparison of specifications of popular models of Kazan
To understand which boat is best suited for your task and the chosen engine, you need to compare the technical specifications of the main modifications. Each model has its own design features that affect the choice of engine and use scenarios.
| Model | Length, m | Width, m. | Passport power, hp. | Load capacity, kg |
|---|---|---|---|---|
| Kazanka (180 project) | 4.00 | 1.60 | 8-10 | 400 |
| Kazanka-M | 4.50 | 1.60 | 12-15 | 400 |
| Kazan 5 | 4.60 | 1.65 | 18-20 | 425 |
| Kazankah-5M | 4.60 | 1.65 | 25-30 | 425 |
| Kazankah-6 | 4.40 | 1.60 | 12-15 | 400 |
As you can see from the table, Kazankah-5M The older and narrower models require an extremely careful approach to engine selection, since their narrow body (their smaller ones) is the most versatile platform for installing an average power motor.1.60m) less stable on course at a sharp set of speeds.
Load capacity is a parameter that is often ignored, forgetting that it includes the weight of the crew, fuel, engine and equipment, and exceeding this limit leads to a decrease in the height of the board above the water, which critically affects safety in the event of a flight. disturbance on a pond.
Security and GIM requirements
Operation of a small vessel requires compliance with the rules established by GIMS. For boats with an engine capacity of more than 5 hp (and under the new rules - for almost all with an engine) is mandatory. registration The existence of rights to manage and the absence of these requirements can lead to serious fines and delay of the vessel.
There should always be a minimum set of equipment on board: life jackets by number of people, anchor with a line, scoop and lifeline. For aluminum boats that do not have unsinkability if completely filled with water (unless additional buoyancy blocks are installed), the presence of vests is a matter of life and death.
⚠️ Attention: According to the rules, the water is prohibited when the waves are higher than the permissible for this type of vessel. For open aluminum boats of the Kazanka type, even moderate chop can become critical due to low surface water on the side and the risk of overflow.
Regular technical inspection is also mandatory, special attention should be paid to the condition of the welds and bottoms. Aluminum is susceptible to corrosion, especially in places of contact with heterogeneous metals or in areas of constant friction (for example, when pulling a boat on the bottom). pebble-bankTimely painting and treatment with anti-corrosion compounds will extend the life of the case for decades.
Exploitation in various settings and care
The Kazanka motor boat is an all-season tool, but it requires proper maintenance. After every trip, especially on salt water or water with a lot of suspensions, the hull must be washed with fresh water. The engine also needs a cooling system wash to prevent overgrowth. chiller salts and algae.
When stored in winter, it is important to ensure that the interior space is ventilated to avoid condensation and dampness, which are harmful to any metal. The boat is better stored under a canopy or covered with a breathable awning, avoiding the use of a dense plastic film that creates a greenhouse effect.
Tip: For prolonged parking on the water (at the beating), be sure to use transom wheels or a suspension system to remove the load from the transom and prevent fouling of the bottom in the area of the daydvut.
Owners often face the need to repair holes or cracks. For aluminum, there are special welding rods and argon welding, but for small defects, you can use epoxy compounds with aluminum chips or cold welding designed to work under water. However, you should remember that any repair is a temporary measure, and at the first opportunity, the defect should be brewed professionally.
A properly fitted Kazanka, with a well-fitting engine, will be a reliable helper for years to come, a rare case in which Soviet engineering combined with modern tuning technology produces results that exceed expectations, the main thing being not to force the vessel’s capabilities and respect the elements.
Key conclusion: Durability and safety of the Kazanka + Motor ligament depends not so much on the engine power as on the quality of transom refinement, proper weighting and regular anti-corrosion care for the aluminum body.
Which motor is better to put on Kazanka-M for fishing?
For fishing in Kazanka-M, the best choice would be a reliable 9.9 hp two-stroke engine (which can often be programmed or mechanically opened to 15 hp). This motor is lightweight, economical and allows you to plane confidently with one or two anglers and equipment. Four-strokes are also good for their silence and economy, but they are heavier, which can be critical for a narrow boat.
Do I need to register Kazanka with a motor up to 5 hp?
According to the current legislation of the Russian Federation (Code of administrative offences and registration rules), boats with an engine of more than 5 hp (or 8 hp depending on the interpretations and year of release of the boat, but now focus on the engine capacity). If the engine is less than 5 hp (3.68 kW), registration is not required, but the presence of rights of category “G” (for engines up to 30 hp) when checking the GIMS can still ask if the vessel is equipped with an engine.
How to deal with electrochemical corrosion in Kazanka?
To protect against corrosion, avoid direct contact of aluminum with copper or brass without insulation. All fasteners must be stainless steel or galvanized. An effective method is to install tread protection (zinc anodes) on a transom or deidval. It is also important to regularly check the condition of the paint coating and restore it if damaged.
Can I put a 40 hp engine on Kazanka?
Technically, it is possible, especially on the Kazanka-5M model, but it requires serious refinement of the translance (strengthening, installing a powerful sub-motorboard), transfer of fuel tanks and cargo to the nose for balancing. However, this is dangerous: the boat becomes unstable, the risk of tipping over sharply increases during turns or excitement. Passport power for 5M is up to 30-35 hp, exceeding it only if you have experience and understand the risks.
