The onset of cold weather for the owner of water equipment is not just the end of navigation, but also the beginning of the responsible stage of conservation of equipment. where to store the outboard motor in winterIt's becoming critical, because the powertrain's life is directly dependent on the wintering conditions next spring, and the wrong choice of space can lead to condensation in the cylinders, carburetor acidification or cracking of rubber seals, which will result in expensive repairs.
Many people mistakenly believe that it is enough to simply drain the fuel and remove the unit into a dark corner, but modern two-stroke and four-stroke The temperature, humidity and even the position of the engine are crucial to maintaining its performance. In this article, we will look at the nuances of choosing a wintering place for your iron horse to start half-around on the first day of the new season.
Criteria for choosing a room for wintering
The first thing to consider when choosing a place is the temperature regime. The ideal option is an unheated, but insulated room where the temperature does not fall below -10 ° C and does not rise above +10 ° C. The sharp temperature changes characteristic of uninsulated metal garages or barns provoke the formation of a new building. condensate inside the crankcase and exhaust system, which is the main cause of internal corrosion.
The second important factor is humidity and ventilation, and the room should be dry, but it can be ventilated, and the full tightness and dampness will create the perfect conditions for the oxidation of electrical contacts and the appearance of mold on plastic casings. flat-roomMake sure the room is well ventilated, as residues of fuel or oil vapor can be unpleasant and unsafe.
The third aspect is safety and protection from mechanical damage: the site must be removed from high-traffic areas so that it does not accidentally hit the unit or drop heavy objects on it. It is also important to consider the weight of the engine: heavy models are better stored on the rack or in limbo to avoid deformation of the lower unit.
⚠️ Warning: It is strictly forbidden to store the engine in close proximity to open sources of fire, heating appliances or in rooms with sparkling electrical wiring.
When choosing between a garage, a cottage or an apartment, weigh the risks. The garage is often too cold, the cottage is wet, and the apartment may not allow you to accommodate the overall cargo. The optimal solution is a compromise between affordability and climatic conditions.
Storage in an apartment: pros, cons and risks
Storage of the outboard motor in flat-room A stable room temperature eliminates the risk of water residue freezing in the pump and prevents condensation, but this option has serious limitations related to size, weight and environmental safety.
The main problem is the residue of fuel and oil. Even after thorough washing and fuel production, the carburetor can still have fumes that can cause headaches or allergic reactions in the confined space of the home, and the smell of gasoline and exhaust gas can absorb into furniture and curtains if the engine is not perfectly preserved.
- 🏠 Advantages: stable temperature, no risk of theft, easy access to check the condition.
- 🚫 Disadvantages: the occupied space, the risk of contamination of housing with oil and dirt, the inconvenience of transporting a heavy unit.
- 👃 Risks: unpleasant odor, potential danger to children and pets (heavy metal, sharp screws).
If you still decide to leave the engine at home, carefully pack it. Use a dense plastic bag or a special case that will protect the interior from possible dust and lubrication. Place the unit on the balcony (if it is glazed) or in the pantry, away from the living rooms.
Can I store the engine on a glazed balcony?
Yes, you can, but only if the balcony is well insulated and the temperature there does not fall below -5 ° C. Direct sunlight can destroy the plastic of the casing, so it is better to cover the engine with a light-tight fabric. Be sure to check the tightness of the windows to avoid snow and rain.
Garage and barn: how to create the perfect conditions
The garage is the most popular place to store boating equipment, but it requires preparation. Metal uninsulated garages ("shells") in the winter turn into a refrigerator, where the temperature drops to street temperature, in such conditions, there is a high risk that the lower unit will remain water, which, if frozen, will rupture the body. pump or gearbox.
For wooden sheds or brick garages, humidity is often the main problem. Underfloor soil or lack of ventilation causes the metal to rust faster than outdoors. To minimize the risks, the motor should be installed not on the concrete floor, but on a wooden stand or dense cardboard to cut off cold and moisture.
It is important to arrange the right position of the unit. The motor must stand upright, like on a boat, or be suspended by a transom bracket. Horizontal position can lead to oil leaking into the cylinder (for two-strokes) or deformation of the crankshaft glands. If space is small, you can remove the lower unit (if the design allows) and store it separately.
| Type of room | Temperature conditions | Humidity | Recommendation |
|---|---|---|---|
| Living room | +18...+22°C | Normal. | Only after complete cleaning of the HSM |
| Insulated garage | 0...+10°C | Medium | The best option |
| Metal garage | -20...+5°C | High (condensate) | Dehumidifier or heating required |
| Wooden shed | -10...+5°C | High. | Lift over the floor, air out |
The main condition for storage in the garage is the absence of direct contact with the cold floor and protection from sharp temperature jumps, causing “breathing” of metal and condensate.
Preservation: mandatory procedures before wintering
No matter where you choose to store the motor, if you don't properly preserve it, it can fail. The preparation process begins with a thorough wash of fresh water to remove salt and dirt. cylinder-preservationTo do this, through the candle hole (pre-twisted candles) in the cylinder inject a special conservation oil or a mixture of gasoline and oil, and then make several turns with the starter.
The fuel system also needs attention. The carburetor needs to be completely emptied of the fuel, because modern gasoline with additives when standing for a long time breaks down into fractions and turns into a resin that clogs the jellyflies. In four-stroke engines, the engine oil is necessarily changed, since the waste oil contains combustion products and acids that can eat the engine parts from the inside during the winter.
⚠️ Warning: Never leave your engine full of gasoline in the winter unless it has a fuel stabilizer. Old gasoline will lose its properties and make starting the engine impossible in the spring without completely disassembling and cleaning the carburetor.
Remember to lubricate all hinge joints, gas cables and rummel with lithium lubricant, which will prevent the mechanism from souring and ensure smooth running in the spring, and it is also recommended to treat external metal parts (except chrome parts of the screw) with an anti-corrosion spray.
☑️ Checklist of engine preparation for winter
Packaging and protection from the external environment
The right packaging is a barrier between your motor and an aggressive environment, and many owners make the mistake of wrapping the motor tightly in a plastic film, creating a greenhouse effect: the slightest change in temperature inside the package, condensates that settles on the metal, causing corrosion, and the motor has to "breathe."
The ideal solution is to use special covers made of breathable materials or ordinary cotton cloth (for example, old sheets), the fabric will protect against dust and accidental scratches, but will allow air to circulate. If you store the motor in a garage where dust from construction work or sawdust is possible, you can use a fabric cover covered with plastic on top, but with mandatory holes for ventilation from below.
When stored upright, make sure the motor is stable. Vibrations from passing vehicles or people's footsteps can overturn the unit. For heavy motors (>25 kg), it is strongly recommended to use a special stand that fixes the lower unit and prevents falling.
Sign the date of the conservation and the list of works performed (what oil is poured, what lubricant is used) on the tag attached to the engine, which will save you time in the spring to remember the details of preparation.
Common mistakes in winter storage
One of the most common mistakes is to keep the motor horizontally on the side. two-stroke This can cause oil from the crankcase to flow into the cylinder and the carburetor, creating an oil plug. four-stroke The oil can enter the combustion chamber through the valves, resulting in the first start of the engine will smoke or not start at all.
The second mistake is to ignore the state pumpIf the last time you rolled out the water from the lower unit was not drained (not allowed to run for a few seconds in the air or not blow), it will freeze. Expanding when you freeze, the ice breaks the rubber impeller pump and can deform the body of the water jacket, repairing such damage is often comparable to the cost of a new lower unit.
The third mistake is to store near heating batteries or radiators, and the overdried air and high temperature affect the glands and gaskets, making them stiff and brittle, and the rubber parts lose elasticity, and once installed on the boat, the engine will poison water or oil.
⚠️ Warning: Do not use pure motor oils with detergents for long-term storage for preservation. They may be hygroscopic. Use special preservation oils or mixtures recommended by the manufacturer.
Keeping these simple rules in mind will avoid 90% of engine start-up and engine problems next season, and remember that time spent on proper canning in the fall will save you money and nerves in the spring.
What if the engine is frozen with water inside?
Don't try to start the engine! Put it in a warm room (+20°C) and let it warm up naturally for 24 hours. Only after full thawing and draining the water can you try to start. Forced heating (dryer, burner) is prohibited.
Frequently Asked Questions (FAQ)
Can I store the outboard motor at sub-zero temperature?
Yes, but only if the water is completely removed from the lower unit and the fuel system is mothballed, but prolonged frosts below -20°C can negatively affect the elasticity of rubber seals and glands, and it is optimal to keep the engine in an unheated but windproof room.
Do I need to remove the screw for the winter?
Remove the screw is not necessary if the engine is stored in an upright position. However, if there is a risk of mechanical damage to the blades or you want to lubricate the screw shaft with a special lubricant (which is recommended to do once a season), the screw is better to remove. Before removing be sure to check the condition of the oss.
How often should you start the engine in winter to warm up?
Starting the engine in winter at home is strictly not recommended. Short work without load and without the possibility of full cooling (in a container with water) will only lead to soak on candles and moisture entering the exhaust system. In winter, the engine should “sleep”.
How to lubricate the outer parts of the engine before storage?
For external metal surfaces, Marine Sprays are best suited to marine corrosion sprays, which create a thin protective film that repels moisture, and ordinary machine oil can attract dust and become sticky.
Is it dangerous to keep your engine close to household chemicals?
Yes, it's dangerous. Some aggressive chemicals (acids, alkalis, solvents) can react with aluminum alloys in the engine body or destroy the plastic elements in the casing. Keep the motor insulated from aggressive chemistry.
