The open water season can start long before you reach the pond if you don’t properly prepare the equipment for the trip. Two-stroke outboard motor It's a sophisticated engineering device that critically dislikes careless handling when moving around in the back or in the cabin of a passenger car. Many PVC boat owners make the fatal mistake of thinking that it's enough to just flip the unit over and shove it into the back seat.
In reality, the process requires a strict sequence of actions, especially when it comes to the process of 2T In power plants, where the fuel mixture plays a key role in lubricating the knots, ignoring transportation rules often leads to the fact that in the resting place instead of fishing, you have to clean the cabin of caustic gasoline or repair damaged dayswood.
The first thing to understand before you start any manipulation is the physics of the process. transmission oilIn addition, vibrations and bumps on the road can destroy fragile elements of the ignition system or damage the lower unit if it is not fixed properly.
Why it is important to follow the rules of transportation
Ignoring basic safety rules during transportation boat-engine It's not only a property hazard, but a real health hazard in the car, and when heated in the sun in a confined cabin, gasoline fumes mixed with exhaust fumes can cause headaches, nausea, or even unconsciousness in the driver, not a theoretical threat, but a reality faced by careless water-engines.
In addition, two-stroke engines are structurally different from four-stroke engines in that they have a fuel-oil emulsion in their crankcase. When the engine is turned upside down, this mixture begins to flow uncontrollably through the carburetor or silencer. Japanese brandssuch as Yamaha or TohatsuThey often have a more perfect sealing system, but they do not guarantee tightness during prolonged inverted state.
⚠️ Warning: Never leave a motor with residual fuel in the trunk of a car for long periods, especially in hot weather, and the vapor pressure can increase so much that even a proper fuel hose will burst, creating a fire hazard.
Mechanical damage is also a serious threat. lower unit, which is the bottom of the engine, is often made of aluminum alloys that are sensitive to impact. If the motor is just lying in the trunk without fixing, any sharp turn or braking can lead to a hit on metal elements of the body or other loads. Restoring the geometry of lower unit is a complex and expensive process that can take weeks.
Preparation of the engine for the trip: drain or production
There are two main approaches to preparation combustion engine Transportation: full drain or production of liquids. The first method is considered to be more environmentally friendly and clean, but it takes time and certain skills. The second method is easier, but leaves the risk of leakage if the engine still has to be tilted.
If you're going to take a path of total devastation, you start with the fuel tank. Disconnect the fuel hose from the engine's plug and let the residue of gasoline drain into the prepared tank. Then you start the engine and let it run to a full stop. This will allow you to generate all the gasoline left in the carburetor float chamber and fuel lines. For two-stroke engines, this is critical, because old oil can coke the channels during long storage.
Don’t forget to check the level too. transmission oil Although it is not necessary to drain it during a short-term transport, it will not be superfluous to check the leakiness of the osteoils of lower unit, and if you notice traces of stains on the bottom of the engine, it is better to replace the seals before the trip, so as not to stain the carpet in the car.
Therefore, even if the motor is “dried”, it is not necessary to put it down with the front side (where the carburetor is located). Carburettor design Such that at a certain position, residual droplets can enter the intake manifold, creating a "water impact" effect on the next start, unless precautions are taken.
Choosing the Right Position When Laying
The question of how exactly to dispose of boat-engine In a car, it's one of the most controversial of owners, and manufacturers usually recommend that you transport it upright, but in a car, that's often not possible, so you have to find compromises that minimize the risks.
The safest horizontal position is to lay the motor on the right side (when viewed from the side of the lower unit). carburetor And the ignition system is on top, which eliminates fuel leakage and moisture from the electrical circuits, and in this position, the oil from the gearbox will not be squeezed out through the oss of the paddle shaft, because the oil level in this part of the gearbox will remain below the seal level.
It is strongly recommended not to lay the motor on the left side or "face" down. transmission oil You can use a sapoon or a gland, and in the second, you can damage the lower unit and get dirt into the water intake system, and if there is no other way out, and you have to put the motor on your face, you can put a soft but dense stand under the lower unit to lift it above the trunk floor.
| Motor position | Risk of fuel leakage | Risk of Damage to lower unit | Recommendation |
|---|---|---|---|
| Vertically. | Missing. | Minimum | Perfect (if the location permits) |
| Right side. | Low. | Medium. | Optimal for transportation |
| Left side. | Highly | Medium. | Not recommended |
| Upside down (on lower unit) | critical | Highly | Prohibited without a special stand |
Fixing and protection against vibrations
Just putting the motor in the trunk is half the battle, and the main danger lies in the dynamics of the movement, when accelerating, braking and cornering, the motor exerts forces of inertia that can move even a heavy unit. fixation It is the only way to protect your equipment and yourself.
Use bracket belts or strong screed belts to attach the motor to the body parts of the car. Never tie the motor to plastic controls, a humming wheel or fuel hoses - these parts are not load-proof and can burst. The mounting points should be on the metal hub of the motor or special eyelets, if provided by the design.
To protect against vibrations and scratches, use tight blankets, specialized covers or sheets of foamed polyethylene. Wrap the lower unit and the bottom of the motor to prevent direct metal contact with the body metal. slab-stove and propeller, which when impacted can not only deform, but also damage the skin of the car.
⚠️ Warning: When using string belts, do not over-tighten them. Excessive pressure on the aluminum body of the motor can lead to deformation of the stan or cracks in the mounting sites of the lower unit.
If you're carrying a motor in a car, make sure you cover the floor and seats with plastic film, and even with the most careful preparation, you can extract residual fuel vapors or oil droplets through microscopic gaps, the smell of gasoline is very persistent, and it's almost impossible to remove it from the fabric cabin without dry cleaning.
Features of transportation in different seasons
The seasons dictate the conditions for transporting equipment, in the summer, in hot weather, overheating and pressure inside the fuel system become the main threat, while in winter, problems with the freezing of residues of water in the cooling system and the fragility of plastic elements in the cold come to the fore.
In summer, try to minimize the time the engine is in a closed car in direct sunlight. The temperature inside the cabin or trunk can reach 60-70 degrees Celsius, which is critical for rubber seals and plastic carburetor parts. If a stop is inevitable, leave the windows ajar for ventilation or cover the engine with a reflective awning.
Winter transportation requires pre-conservation of the cooling system. Even a small amount of water left in the cooling shirt will expand when frozen and can break the cylinder block or pipe. Be sure to blow the system with compressed air before loading on a frosty day or use non-freezing liquids if allowed by the instructions to your vehicle. motor.
Also, in the cold, plastic becomes brittle, and if you hit a motor or crash at subzero temperatures, you can chip plastic casings and handles that would withstand similar loads without damage in the summer, and be especially careful when loading and unloading in the winter.
Cleaning and maintenance after transportation
Once you have brought the motor to the water or brought it home, do not rush to put it on the boat or put it in the garage. Proper maintenance after transportation will prolong the life of the unit. First of all, you need to check whether moisture or dirt has entered the ignition system and the candle.
If the motor was transported horizontally, it is recommended to wait 10-15 minutes in an upright position before the first start, which will allow oil and fuel to flow into the lower parts of the crankcase and gearbox, restoring normal lubrication levels.
Be sure to wipe the outer surfaces of the engine with clean rags, removing traces of gasoline, oil and road dust. fuel pump The presence of dirt in these components can lead to clogging of the jelly and unstable operation of the engine on the water.
Frequently Asked Questions (FAQ)
Can you carry a two-stroke engine upside down if you drain all the gasoline?
Technically, if the fuel is fully developed, the risk of fire is minimal. However, transport on a lower unit (screw up) is highly undesirable because of the risk of damage to the propeller, anti-cavitation stove and water or dirt getting on the water intake system. In addition, oil from the gearbox can leak through the glands, since they are not designed to retain fluid in this position of the shaft.
Do I need to disconnect the fuel hose on a short trip to the reservoir?
Yes, you have to unplug the hose before you load it into the car, and that will prevent the system from leaking out as the tank or the engine changes position, and even a short trip on rough roads can create pressure in the hose leading to leakage.
Is it dangerous to carry the engine in the cabin of a car?
This is only permissible if the engine is perfectly tight (full fuel production) and securely fixed. However, the risk of gas vapor poisoning and damage to the cabin in case of accidental leakage remains high. Experts recommend transporting the engine in the trunk of a station wagon or hatchback with an open hatch and running ventilation, or in a trailer.
How to protect lower unit from scratches during transportation?
The best way is to use a special transport case with soft liners or to wrap lower unit yourself in a dense cloth, cardboard or foamed polyethylene, and you can also use a plastic container (pelvis or a cropped canister), wearing it on the screw and bottom of the lower unit.
What to do if the engine does not start after transportation?
The most common problem is a plug after the engine is tilted, twist the candle, dry it, and blow the cylinder, pulling the starter several times, if that doesn't work, check for sparks and fuel, and maybe dirt or water has hit the carburetor.
