Choosing a power unit for a light inflatable boat or a small boat always involves finding a balance between power, weight and cost. motor Galo 12 It is a leading model due to its affordability, and has become a popular alternative to more expensive brands, offering a stated 12 horsepower for a reasonable price.
Owners of small boats are often looking for a power class that allows you to plane with one or two passengers on board. Galo 12 It is positioned as a versatile engine for fishing and recreation on the water, but like any mass market equipment, it has its own design features and maintenance nuances that you need to know about before buying.
In this article, we will take a look at the specifications, the process of running and the typical problems that users face, and understanding the design of this motor will help to extend its life and avoid unforeseen breakdowns on the water.
Technical specifications and design features
The powertrain is based on a two-stroke internal combustion engine, and this design is not accidental: the two-stroke cycle provides high torque at low revs, which is critical for full-load plane. The cylinder displacement is 196 cubic centimeters, which is standard for a 10-12 hp class.
The cooling system works by taking off-shore water through a water intake in lower unit, which is an effective method, but it requires careful attention to the purity of the reservoir. pompThe vent, or water pump, is one of the key nodes that circulate fluid through the cooling shirt and the thermostat, and overheating is most often due to problems in this circuit.
Before the first start, be sure to check the oil level in the gearbox. Factory lubrication may be absent or not filled to normal.
The dry weight of the motor is about 26-28 kilograms, which makes it easy enough for one person to carry, but heavy enough for long transport in the trunk of a passenger car without a trolley.
Letβs look at the main parameters in the table for ease of comparison:
| Parameter | Meaning |
|---|---|
| Power | 12 hp |
| Workload | 196 cc. |
| Type of fuel | AI-92 + butter (1:50) |
| Ignition system | CDI (electronic) |
| Recommended screw | 9.25 x 10 inches |
The breaking in process: rules and recommendations
Running is the most important stage in a new engine's life, and many beginners neglect this process by starting the engine at full power, which is a grave mistake. Piston group And the rings must be worn against the cylinder walls, and if you put the full load right away, the micro-nervousness of the metal can cause bullies, which will lead to loss of compression and major repairs.
It takes about 10 hours, and the first two hours are recommended to run at idle speeds without opening the throttle by more than 30 percent, which allows the oil to spread evenly across all the friction nodes, and water is mandatory, and even a few minutes of dry work can kill the pump.
βοΈ The Galo 12 break-in plan
After the first two hours, you can gradually increase the load by adding 10-15% of the power each hour, and it is important to avoid long periods of constant revs; modes need to be changed. Galo 12 It requires cyclical loading for proper laundry.
β οΈ Warning: Never run on full gas! this can cause permanent damage to the piston and cylinder due to local overheating.
After the procedure, the oil in the gearbox must be replaced, even if the manufacturer claims that it is filled forever, and when the gears are laundered, metal shavings enter the oil, which must be removed.
Fuel mixture and power supply
Because the engine is two-stroke, it doesn't have a separate oil crankcase, and the lubrication is done by oil added directly to the gasoline. Galo 12 This is 1:50 for the break-in engine and 1:25 for the break-in period. Use of high-quality two-stroke oil for outboard motors (TC-W3) is mandatory.
Gasoline should be used at least AI-92. Higher octane fuel (AI-95) is not recommended, as in two-stroke engines with air or water cooling, it can burn at higher temperatures, causing detonation and burnout of the piston. Fuel filter-sludge, located in the tank or on the hose, you need to regularly check for water and dirt.
How to mix fuel properly?
Pour the right amount of gasoline into the canister first. Then add a measured amount of oil. Shake the canister thoroughly for 1-2 minutes before you get a homogeneous emulsion. Do not store the mixture for longer than 2-3 weeks, as it loses its properties and delaminates.
The carburetor is set up in the factory, but over time, adjustments to the quality of the mixture may be necessary. If the engine stalls on idles or "chokes" when a gas is opened abruptly, quality and quantity screws may need to be adjusted.
Typical malfunctions and methods of their elimination
Like any technique, Galo 12 It's prone to wear and tear, and most often, owners have problems with their ignition or fuel system. Ignition candle The first element to check when starting is difficult, and the candlestick can tell you about the state of the engine: black soda indicates a rich mixture, white indicates poor or overheating.
Another common problem is cutting off the flywheel veneer or the starter gear, which happens when you try to start the engine with the gear on or when you jam the screw against the algae. starter In such cases, it can scroll idly or emit a characteristic crackle.
- π₯ No spark: Check the candle, the cap and the ignition coil. Often the contacts under the flywheel are oxidized.
- π§ Extraneous noise: May indicate the production of crankshaft bearings or the entry of a foreign object into the screw.
- π‘οΈ Overheating: Check the water control hole. If the jet is weak or missing, the pump is likely to malfunction or the cooling channel is clogged.
Diagnosing often requires removing the casing. Be careful with plastic latches, they can be brittle in the cold or after long use.
80% of problems with starting a two-stroke engine are related to the quality of the fuel mixture or the state of the spark plug.
Selection of screws and speed specifications
A regular propeller, which comes with the engine, usually has a pitch designed for the average boat. However, to achieve maximum speed or better traction with heavy loads, it may be necessary to replace the propeller. Galo 12 It is standard, which allows you to use analogues from other manufacturers, for example, Mercury or Tohatsu.
Reducing the pitch of the screw will allow you to gain speed faster and improve traction when the boat is fully loaded, but reduce the maximum speed. Increasing the pitch, on the contrary, will raise the maximum speed on a light boat, but the engine may not reach working speeds, which is harmful to the engine. The optimal range of revolutions for maximum power is 5000-5500 rpm.
When choosing a screw, pay attention to the material. Aluminum screws are cheaper and easier to repair (they can be manipulated), but they are less efficient at high speeds. Stainless steel is more expensive, but provides better efficiency and durability, although hitting a stone can damage lower unit.
Conservation and storage in the off-season
Properly storing the engine in winter or during prolonged downtime is the key to its longevity. You can not leave gasoline in the carburetor and fuel hoses: light fractions evaporate, and resinous residues clog the jelly. Conservation It starts with the complete discharge of fuel from the system.
To protect the cylinders from corrosion, you pour about 10-15 ml of special conservation oil (or conventional two-stroke oil) into the candle hole and make a few turns with a starter, which will create a protective film on the cylinder mirror and the piston.
- π’οΈ Replace the oil in the gearbox before storage so that the acidic environment from possible water ingress does not corrode the gears.
- π§Ό Carefully rinse the engine with fresh water, especially if the operation was in a salt water body, and lubricate all movable hinges.
- π¦ Keep the motor upright so that water does not get into the muffler and cylinder through the exhaust hole.
β οΈ Note: Do not store the engine in a room with working gas appliances or open fire if there are gasoline vapors in the tank or carburetor.
Comparison with competitors and final conclusions
In its price segment Galo 12 It competes primarily with other Chinese brands like HDX, Sea-Pro and more expensive Japanese used parts, with the main advantage of price and availability, and structurally repeating the time-tested solutions of Yamaha and Tohatsu, making repairs easier.
But the quality of the casting and assembly can vary from batch to batch, with a hummel backlash or a less than perfect painting, yet for the money it's one of the most rational choices for an amateur who doesn't plan to set speed records, but just wants to fish comfortably.
So to sum up, it requires a careful attitude during break-in and high-quality fuel, and if it's met, it can run hundreds of hours of motorcycling, bringing joy to the water.
Frequently Asked Questions (FAQ)
Which petrol is better to pour in Halo 12: 92nd or 95th?
The high-octane 95th gasoline in two-stroke engines burns more slowly and at a higher temperature, which can lead to overheating of the piston group and detonation if the engine is not specifically tuned for it.
How many hours does the oil in the gearbox need to be changed?
The first oil change in the gearbox should be made immediately after the end of the break-in (after 10 hours), then the procedure is repeated every 50-100 hours or once a season, preferably before winter storage.
Why does the engine stop at high speeds?
This is most often a poor mixture (lack of fuel) or problems with the ignition system (lack of spark under load), and it is also worth checking the fuel filter and ventilation of the tank - if the tank does not get air, there is a vacuum and the fuel stops flowing.
Can you use Halo 12 at sea?
Yes, you can, but after each trip, you need to thoroughly wash the cooling system and the outer parts with fresh water, and salt water causes rapid corrosion of aluminum alloys and magnesium anode, which must be changed more often than when used in fresh water.
