Motors for medium power boats are the most common units, which contributes to the optimal power potential of such units. They allow you to meet the needs of different users, coping with traction loads for up to 4 people. The UMP plant presents on the market the Veterok outboard motor in several modifications and at reasonable prices. The 8M series outboard power unit can be considered as the most popular model, which is characterized by high maintainability and durability, but subject to maintenance and operation measures. Against the background of competitors, the unit can lose in power traction, but it does not cause complaints in terms of speed and reliability - perhaps this is facilitated by the ease of its assembly and repair.
General motor information
In accordance with the manufacturer’s recommendations, the Veterok 8M motor can be used on boats with a transom height of 38 cm. At the same time, the reservoir depth should be at least 50 cm. The engine is equipped with a contactless electronic ignition system, and also has the ability to connect devices that feed signal lights. For launching, the Veterok 8M outboard motor is equipped with a starting mechanism supplemented by a retractable cord. Due to the low placement of this device at the time of starting, the folding force of the unit is reduced.
The cooling of the “Veterok” power plant is carried out by means of a special pump that takes water from the reservoir. The user monitors and controls the motor using the tiller. For comfortable use, the unit is equipped with a holder for the reclined position, an idle clutch and a spring-type suspension, which levels the vibration broadcast to the boat.

- The number of cylinders is 2.
- The cylinder diameter and working volume are 5 cm and 173 cm 3, respectively.
- Piston stroke - 4.4 cm.
- The draft on mooring lines is about 70 kgf.
- Ignition system - provided by the MBE3 system with external transformers.
- The carburetor model is K-33B.
- Fuel consumption per hour - 3.2 liters.
The principle of the motor
The “Veterok” power unit performs a drive function in a 2-stroke cycle, in which a crank-chamber deflector blowing is also involved. During operation, suction, compression, stroke and exhaust are performed — this cycle is performed in two piston strokes, which also corresponds to one crankshaft revolution.
In the crankcase cavity, when the piston moves upward, a vacuum forms, as a result of which the working mixture leaves the carburetor in the free cavity - this happens when the intake valve opens. At the moment of the lower piston movement, the valve closes automatically, and the mixture in the crankcase is compressed. When the exhaust and purge windows, which the Veterok outboard motor is also equipped with, open, the working mixture flows from the crankcase into the cylinder. Thus, purging of the cylinder cavities and its further filling with a new mixture is performed.
Ignition system
Electronic contactless ignition is one of the main features that distinguish the Veterok 8 outboard motor. The characteristics and composition of this device are as follows:
- thyristor - series KU202M;
- diodes - series KD209A;
- capacitor - charge 400 W;
- resistor - resistance 0.5 Ohm;
- spark plug - element A11-3;
- transformer;
- control and storage windings of the ignition coil ;
- winding for a lighting coil;
- incandescent lamp.
In general, the electronic ignition of the Veterok outboard motor includes a flywheel magdino, two remote transformer systems and two spark plugs. The flywheel, in turn, is equipped with four pole shoes and three permanent magnets. Four cables come out of the base of the magdino: to ground, to the lighting system and two are connected to the transformers of the cylinders (upper and lower).
Launch system
Activation of the “Veterok” power unit is carried out by means of a manual mechanism, in which a self-retracting cord is also provided. At the moment of pulling the cord by the handle, the rotation of the pulley in two bearings begins, and the gear due to the brake spring and screw slots enters the clutch with the flywheel - there is a coupling with the ring gear. Then the crankshaft is cranked and the outboard engine "Veterok" is started. In this case, the gear and the flywheel diverge.
When the cord handle is released, the spring causes the pulley to rotate in the opposite direction. If during operation malfunctions of the mechanism are detected, it is possible that the engagement of the flywheel and gears should be adjusted. This is done by installing the pin in the pulley, that is, in one of its holes.
Underwater device
The spacer in its upper area has a whole range of functional elements. Among them are four screws, a glass with ball bearing and oil seal, as well as a water intake pump. The water is drawn through a special tube, and a sleeve of rubber is provided between the glass and the frame of the pump, which seals the output section of the idle clutch. The coupling itself includes two elements - one of them is the idle drive gear and is attached with a pin to the vertical shaft, and the driven component moves along the drive splines by means of a fork. The oil seal pressed into the cup forms the optimum seal on the shaft.
The gearbox with which the Veterok outboard motor is equipped can be represented as a bevel gear. The connection of the device body and spacers is provided by two studs. Here, in the interval between the spacer and the gearbox, gaskets are provided for adjustment.
Motor installation procedure
The unit is combined with boats whose transom height is about 38 cm. If the model has a transom of a different size, then it must be artificially adjusted to the optimum height. The fact is that an insufficient value for this parameter is reflected in the form of a decrease in speed, since the underwater region receives greater resistance. In this regard, it should be borne in mind that the size of the Veterok outboard motor, although not a deviation from the standards, presupposes its own nuances in the installation - 35 cm in width, 50 cm in length and 105 cm in height.
When installing, the unit should be installed so that the supports enter along the entire depth of the grooves on the transom. Next, you need to securely fasten the structure with screws. During operation, it is necessary to systematically check the quality of fixation. The motor is mounted strictly in the middle of the transom - only this arrangement will provide a direct course, in other cases, a tangible tilt of the boat to the side when moving is possible. In ready-to-use form, the Veterok outboard motor, the photo of which is presented below, has optimal horizontal propeller placement . This may require adjustment of the stop in the suspension support grooves.
Maintenance
Like any complex technical unit, the outboard motor provides for regular routine inspection and correction of “suspicious” systems and elements. In particular, it is necessary to periodically inspect the candle electrodes, tighten the screws, bolts and nuts, check the quality of the control panel fixing to the suspension, etc. A rather complicated system in terms of maintenance is the ignition of the Veterok outboard motor, since troubleshooting requires the use of an ohmmeter. With this device, you can detect shorted winding leads, problems with the thyristor, capacitors or diodes. Well, the presence of oil is checked without fail. Qualitative composition will extend the working life of the motor, so a systematic check after 25 hours of operation should become the norm.
Trouble-shooting
In motor boats, the power plant is the main source of technical problems. Its failure can be triggered by various reasons, including lack of fuel or improper carburetor adjustment, excessive fuel, valve damage, etc. Some of these problems can be resolved by purchasing a new spare part for the Veterok outboard motor - the need for updating may affect the valve in the crankcase , impeller with key, gaskets, dampers and other elements. But it happens that the restoration of performance can also be realized by elementary adjustment of the same carburetor, suspension, shift clutch or by introducing new devices such as an intermediate frame into the design for a deeper landing of the motor.
Motor Parts
The manufacturer provided for the repair kit the entire list of spare parts, as well as components and assemblies, which are equipped with the outboard engine "Veterok 8". Spare parts available for home repairs include gaskets, valves, oil seals, piston rings, springs, pins and other elements.
For a more thorough repair, you may need a pipe, crankshaft, crankcase cover, middle support, cylinder head, etc. In addition, there are special tool kits that repair the motor. These are wrenches and socket wrenches, flywheel pullers, screwdrivers and wrenches. As additional accessories, owners should also pay attention to the fuel tanks, hoses and a cord for starting with a handle.
Motor reviews
The Veterkov family has existed for several decades, and to this day its representatives are in demand in the boat equipment market. The first motorcycle hours of engine operation can upset with low power. Rather, the claimed 8 "horses" do not disappear, but experienced users note the lack of traction available to the Veterok outboard motor. Reviews also note frequent breakdowns, blockages, as well as an uncomfortable landing, due to which preventive examinations become mandatory almost after each use.
But there are pluses, thanks to which the domestic motor has retained its popularity, and not only in Russia. First of all, it is distinguished by maintainability. This means that the engine can not only be repaired, but do it yourself from a standard set of public spare parts. That is, breakdowns are frequent, but they are easily repaired, while foreign four-stroke competitors break even less frequently, but there are much more problems with subsequent repairs. The rest of the “Veterok” shows decent results both at full speed and in trolling. For example, fishermen's opinions about him are mostly positive - among medium-sized outboard engines it is not easy to find a high-quality and inexpensive copy, and the Veterk justifies itself in many ways, despite all the disadvantages.
