History of creation and design features
The development of this engine began in the middle of the last century at the engine plant in Naberezhnye Chelny, which was originally a military project, requiring maximum reliability in the field. two-stroke Internal combustion was designed with a large margin of safety and a minimum number of complex components.
The engine is based on a time-tested crank-chamber purging scheme, with a cylinder capacity of 494 cubic centimeters, which allows for 12 horsepower, an outstanding performance for its time, providing excellent traction even on loaded boats.
- 🔧 Two-cylinder engine with reciprocating and looping provides stable operation on all modes.
- ⚙️ The lower unit water cooling system effectively removes heat, preventing the piston group from overheating.
- ⚓ Turning lower unit allows you to control the direction of movement of the boat by turning the entire motor around the vertical axis.
Particularly noteworthy is the ignition system, which in the early models was magdin type, and in later versions received electronic contactless ignition, which significantly improved the start in cold weather and the stability of work at high revs. Ignition coil In modern versions, it has become more reliable and less often requires intervention.
⚠️ Note: When using old models with magdin ignition, it is critically important to monitor the state of the interrupter contacts, since their oxidation leads to the loss of spark and engine stop.
The body of the engine is made of aluminum alloy, which reduces the overall weight of the structure, but requires careful treatment during transportation. The mechanical strength of the parts allows the engine to withstand significant vibration loads. Despite the solid age of the structure, spare parts for the construction of the engine are not very expensive. salute You can still find them in specialty stores or at showdowns.
Technical specifications and parameters
Understanding the exact technical parameters is necessary for the correct tuning of the carburetor and the selection of the propeller. Engine power 12 hp is achieved at a crankshaft speed of about 4500-5000 rpm, which is the optimal range in which the engine operates most efficiently and economically.
The fuel system uses an AI-92 or AI-95 mixture of gasoline with engine oil for two-stroke engines. The mixing ratio is usually 1:25 for break-in and 1:30-1:40 for continuous operation, depending on the oil manufacturer's recommendations. The quality of the mixture preparation directly affects the life of the piston group.
The weight of the motor in running order is about 26-27 kilograms, making it heavy enough to carry by one person, but acceptable for installation on boats with lengths of 3 to 5 meters.

The gearshift system is mechanically implemented through the cable drive or traction, providing three positions: forward, neutral and reverse. gearboxThe smoothness of the switch depends on the correct adjustment of the cable and the state of the curtain.
Rules of running and first start
The break-in process is a critical step in determining engine durability: new piston rings and cylinders must blend in with each other in a gentler temperature regime, and ignoring this stage often leads to bullying and the need for major repairs in the first season.
The first start is best done in a barrel of water or on a suspension, providing free exhaust and water intake. Flow-in mix It should be richer in oil than the working oil, usually in a ratio of 1:20 or 1:25, which will ensure high-quality lubrication of rubbing surfaces during their working time.
☑️ Checklist for break-in
The break-in time is approximately 10 hours, and in the first hours, avoid full-speed and long-duration idling, and the optimal mode is variable load: a few minutes of medium-speed operation, then gas discharge and set speed again.
⚠️ Warning: Never keep the motor idling during break-in, as this leads to candles coking and uneven heating of the cylinders, which can cause parts to deform.
After the first 5 hours of operation, drain the old fuel and replace it with a fresh mixture, and it is also recommended to check the tightening of all bolt joints, since vibration during the laundry period can weaken the fastener. Ignition plugs After the scorching, you should look and see the scorching.
The secret to successful breaking in
Many experienced motorists recommend adding a little castor oil (about 50 grams per tank) to the fuel tank after the first 5 hours of work, which has excellent lubricating properties and helps to form a strong oil film on the cylinder walls, although modern synthetic oils for two-stroke engines already contain the necessary additives.
Reduction gear and propeller
The gearbox is one of the most loaded components that transmits torque to the propeller. Inside the body, there are a pair of gears that reduce the speed and change the direction of rotation. Lubrication is done with a special thick oil that is laid inside the body.
The propeller is designed to maximize efficiency at a given engine power. The standard propeller pitch allows speeds of up to 25-30 km/h on a light boat. Damage to the propeller blades can cause imbalance and destruction of lower unit bearings.
- 🛠 Regular oil change in the gearbox prevents water from entering and corrosion of the gears.
- 🔩 Checking of the lower unit glands should be carried out annually before the navigation.
- 🌊 The use of antifouling coatings on lower unit reduces water resistance and shell fouling.
If you hear a hum or howl coming from the bottom of the engine, this is a sure sign of problems with bearings or gears, in which case you must immediately stop operation and make a defect of the unit. Repair of gearbox It requires special detachers and presses to press bearings.
It is important to monitor the condition of the slats joint of the propeller. Wear of the screw leads to slipping of the screw under load, which is loss of speed and jerks. To protect against impacts on underwater obstacles, a safety pin or friction clutch is used, depending on the modification.
Typical malfunctions and methods of their elimination
During operation, owners may face a number of characteristic problems, most often associated with the power or ignition system. Engine Salute It is easy enough to diagnose most malfunctions on your own, with a minimal set of tools.
If the engine doesn't start, the first thing you need to do is check for a spark. Twisted the candle, threaded it against the mass of the engine, and pull the starter. If there's no spark, check the coil, the capacitor, and the high-voltage wires. Often the problem is oxidized contacts or broken insulation.
When looking for a fault, always start with the simplest: check if there is fuel in the tank, if the crane is open and if the fuel system is not clogged. 80% of problems are solved at this stage.
High-speed interruptions often indicate a leaky crankcase or air pump through the crankshaft coils. A two-stroke engine is very sensitive to depressurization, as it disrupts the process of cylinder purging. Carburettor membrane It can also lose elasticity over time, which requires replacement.
| A symptom. | Possible cause | Decision |
|---|---|---|
| Deaf to singles | Contaminated jikler XX | Clean the carburettor. |
| No spark. | Magdino malfunctioning. | Replace the coil/capacitor |
| Overheating | Clogged chiller shirt | Clear the cooling channels |
| Dymite | Lots of oil in the mix | Adjust the proportion |
Knocking in the engine may indicate wear of the root bearings or the rod group. Operating the engine with such symptoms is strictly prohibited, as it can lead to jamming and destruction of the cylinder block, in which case a complete bulkhead of the engine with replacement of worn parts is required.
Maintenance and conservation for the winter
Properly storing the engine in the off-season significantly prolongs its life, after the navigation is over, you need to drain the remnants of the fuel mixture from the tank and carburetor, gasoline loses its properties over time and forms a resinous plaque that clogs the jelly.
The motor should be thoroughly washed with fresh water, especially if it was operated in salt water, and after washing, let it dry completely. Conservation of cylinders is made by injection of special conservation oil through candle holes and several turns of the crankshaft.
Keeping the motor upright in a dry room is best, and it is not recommended to cover it with polyethylene, as this can lead to condensation and corrosion. It is better to use breathable cloth covers.
⚠️ Before long storage, be sure to lubricate all external hinges and cables with a consistent lubricant to prevent them from souring by the next season.
Regular maintenance, including replacement of oil oils, bearings and cleaning of the carburetor, will allow you to use your carburettor. salute ES outboard motor This unit has earned its reputation as an unkillable helper, but it also requires respect and timely care.
