The legendary aluminum boat Kazanka M It is widely regarded as one of the most popular floating craft in the post-Soviet space, but the standard design of this model, developed in the middle of the last century, did not initially involve the installation of powerful outboard motors and complex steering equipment. In the basic configuration, control was carried out either by a tiller or a simple cable, which at high speeds and under heavy chop often proved to be insufficiently efficient and safe.
Modern requirements for comfort and safety dictate their conditions: owners strive to modernize their homes. aluminum boatsThis is not just a matter of convenience, but also the need for accurate control of the trajectory, especially when using motors with a capacity of more than 15-20 hp. Properly selected and mounted steering radically changes the behavior of the boat on the water, making the course more predictable and calm.
In this article, we will discuss all the nuances of modernization in detail. Kazan M.You will learn about the types of mechanisms available, the features of their installation on the narrow transom of this model, and also get practical tips for maintenance of the nodes. The right choice of components will turn the good old Kazanka into a modern, comfortable boat, ready for serious walks on large reservoirs.
Design features of Kazanka M and the choice of the type of control
Before you start purchasing components, you need to clearly understand the design limitations of your boat. Kazanka M It has a relatively narrow transom and a specific shape of the feed, which imposes restrictions on the dimensions of the equipment being installed. Staffing places often require additional brackets to be modified or manufactured, especially if it is a question of switching from the tiller control to the remote control.
There are two main types of systems on the market that are suitable for this model: mechanical (steering) and hydraulic. Mechanical steering is based on a system of cables and gearboxes. This is the most budgetary and common option, which is great for engines up to 50-60 hp. The cable systems Easy to install, easily repaired in the field and not afraid of mechanical damage to the body.
Hydraulic steering is a choice for those who value maximum comfort and have more powerful motors. Hydraulics ensure smooth running of the tube, no backlashes and feedback that can not be obtained on the cable. Kazan M. Installation of hydraulics can be a difficult engineering task due to the lack of space for the pump unit and hydraulic cylinder, as well as the high cost of the kit.
⚠️ Note: When installing any system on Kazanka M The aluminum from which the boat is made becomes tired over time, and drilling new holes under the steering machine fasteners should be done only after assessing the thickness of the metal and the presence of internal amplifiers.
The choice between cable and hydraulics often comes down to budget and engine power. If you use a motor up to 30 hp, then the quality of the engine is high. mechanical For motors of 40 hp and above, it is worth thinking about hydraulics or mechanics with a reducing gear ratio, so that the tiller forces remain comfortable even when driving against wind or wave.
Mechanical steering: types of cables and gearboxes
The basis of the mechanical system is the steering cable, which transmits rotational motion from the gearbox (steering machine) to the motor bracket. Kazan M. The most relevant cables are SS (Soft Soft) or SSU. SS This means that both ends of the cable are soft, making it easier to lay in the tight areas of the narrow hull of the boat. The length of the cable is selected individually, but for Kazanka M, it is usually enough 3 meters (10 feet), although it is better to take with a margin.
A steering machine is a mechanism that converts the steering wheel into the forward motion of the cable. When choosing a gearbox, consider the number of revolutions from side to side. The standard value is 3.5-4 revolutions. Less revolutions will make steering sharper, which at high speed can be dangerous, and more - too "sluggish."
The important element is the steering wheel itself. Kazan M.Where the cockpit is often limited, 300-330 mm steering wheels with a comfortable, non-slip handle are ideal. Using a too large steering wheel can be uncomfortable due to lack of space, and a small one will require a lot of effort to shift the course.
When laying the cable, avoid sharp bends with a radius of less than 20 cm. This can lead to a jamming of the inner vein and the destruction of the shell, which will disable the system at the most inopportune moment.
Material quality is critical. Cheap plastic-coated cables quickly lose their lubrication and start to crunch. For long-term use, choose double-corrosion-proof cables and waterproof lubrication inside, because you can use them for long-term use. saltwater The constant humidity quickly breaks down the unprotected metal.
Hydraulic system: is sheepskin worth making?
Hydraulic steering on Kazanka M The main advantage of hydraulics is that there is no rigid mechanical connection between the steering wheel and the motor, which means that the waves hit the steering wheel or the screw are not transmitted to the steering wheel's hands, and the steering wheel is always returned to neutral position due to the operation of the valves.
The system consists of a steering pump (built into the steering wheel or separate), a hydraulic cylinder (actuator) mounted to the motor and connecting hoses. Kazan M. The main problem is the placement of the cylinder. Due to the narrow stern, the cylinder can rest against the side or transom at a complete turn, so it is often necessary to make an individual mounting bracket made of stainless steel or aluminum.
Another important aspect is pumping the system: hydraulics do not tolerate air in the circuit; the presence of bubbles leads to a "cotton" steering wheel and loss of controllability; the process of filling the system with special hydraulic oil requires accuracy and adherence to the technology described by the kit manufacturer.
| Comparison parameter | Mechanics (Tross) | Hydraulic |
|---|---|---|
| Cost of kit | Low/Mediocre | High. |
| Difficulty of installation | Medium (you can do it yourself) | High (experience desired) |
| Service | Lubrication, integrity check | Replacement of fluid, check of hoses |
| Comfort of steering | Depends on the effort on the propeller. | Maximum, smooth. |
Despite the difficulties, hydraulics Kazanka M It does wonders. The boat becomes docile, the yaw disappears, and the one-fingering becomes a reality even at full throttle, and if you plan to go on long walks or with passengers often, investing in hydraulics will pay off.
Preparation of the trans manoeuvre and installation of the steering machine
Installation begins with careful preparation of the installation site. Kazanka M The slant is often tilted, which must be considered when marking up, the steering machine must be installed strictly horizontally to prevent skewed cable and uneven wear of gears, and often use additional aluminum adapter plates.
Drilling holes in the aluminum case is a responsible operation. Use only sharp metal drills designed for aluminum, so as not to "smear" the edge of the hole and create a focus for future corrosion. After drilling, the holes are necessarily zonkuyu and treated with anticorrosion composition.
☑️ Checklist for installation
The fastening is carried out on bolts with a wide hat and the mandatory use of Grover's washers to prevent self-unwinding from vibration. sea-sealerDon't skimp on sealants: water trapped inside a transom Kazan M.This can cause serious problems with the buoyancy and integrity of the structure.
After installing the machine, check the lightness of the shaft. There should be no snacks. If the shaft is scrolling tightly, the body of the machine may be skewed or the fastening bolts are too tightly tight.
