Лодки используются как для водных прогулок, так и for fishing. There are various options, ranging from costly cumbersome duralistic options to small rubber ones. For convenience of use, the boats are equipped with engines, the two-stroke ones are most widely used.
A boat engine, being a complex mechanism, withthe work of which occurs friction, does not do without engine oil. His choice should be treated with special care, as it affects the life of the device.
The main difference between four-stroke and two-strokemechanisms is that for the latter a mixture of gasoline and oil is used. Therefore, the lubricant must meet other standards. During combustion, there should be no release of a large mass of combustion products to prevent their settling on internal elements. Also, the oil for two-stroke engines must be completely mixed with gasoline and burned simultaneously with it. If a lot of fumes and soot are produced during operation, then the engine resources and its power characteristics will decrease, and the expense, on the contrary, will increase.
Существует два основных вида масла:synthetic and mineral. The latter is produced in the refining process. Compared to synthetic, it has a lower cost. Quality characteristics are also at a lower level. The properties of the oil change at high temperatures, the structure becomes less dense, there is a possibility of engine failure.
Synthetic oil for two-stroke engines,For example, Motul Outboard, does not contain impurities that are dangerous for the mechanism, but differs in its relatively high cost. It is justified by the safety and long-term use of the composition, as the oil retains its original characteristics even in hot weather and with intensive engine operation.
Each lubricant is suitable for different situations and needs of the owners. User priorities may be different: someone chooses reliability, and someone wants to save.
Despite the abundance presented in storesModern engines, often found boats with mechanisms, whose age is 30-40 years. And in terms of efficiency, they are not inferior to the new options: they provide for maneuvering in dangerous, difficult areas and fast acceleration. At the same time, the resources of most of them are gradually being developed, the smallest cracks in the cylinders, imperceptible to gaze, appear. Despite their small size, they increase noise during operation, increase fuel consumption and lead to a decrease in power.
In such situations, oil becomes irreplaceable.two-stroke, the price of which does not exceed 600 rubles, with special additives. Compared with lubricant, they are characterized by a greater degree of viscosity, so that the surface coated with additives becomes smoother. Due to this, the characteristics of a worn out motor are improved. Of course, sooner or later, repairs will still be needed, but there is no more suitable option as a temporary measure. It is worth noting that there is an opinion that the additives harm the motor, but it has no basis. Quicksilver two-stroke oil with additives is best suited for the average intensity of use of the engine.
The modern range of oils presented is notonly mineral and synthetic means, but also options for four-stroke and two-stroke engines. Lacking sufficient knowledge, owners of two-stroke engines acquire the wrong two-stroke oil. Its use leads to the fact that when the piston moves, its particles are preserved and turn into ashes. The mechanism continues its work in a large amount of ash, which subsequently leads to a serious and expensive repair. Therefore, it is strictly prohibited to use oils of an inappropriate type.
It is also worth remembering compliance with establishedproportions. For operation in standard mode, the proportions should be 50: 1 (gasoline and two-stroke oil, respectively). It is necessary to treat the new motor more carefully and change the ratio to 25: 1.
In order not to be mistaken with the choice, you need at leastread the instructions that are on the canister with the composition, or ask for advice from a specialist. It is undesirable to get the first available oil. So you can harm even the Russian unpretentious mechanism. For example, if standard two-stroke outboard mineral oil is used for a complex Yamaha engine, there will be no problems at first, but over time the engine will often stall and the power will decrease. The reason is that after the collapse of the mineral-type oil, a large amount of ash remains, which causes the combustion chamber to become clogged. The result is primarily a decrease in power. Also, the motor may fail when untimely cleaning and prolonged use of the wrong composition. Therefore, when operating a boat with a foreign engine, it is not worth saving, it is better to purchase two-stroke motor oil MANNOL or Makita for fastidious devices.
It is recommended to buy oils in specialretail outlets engaged in the implementation of motors, boats and parts for them. You may have to pay a little more. For example, the composition of MANNOL in a liter pack will cost at least 400 rubles, while on the market you can find 300-350 rubles. But it’s not just that many doubt the origin of products sold in the markets and their quality.
For the year, two-stroke oil is consumed not in suchlarge quantities to try to save. It is better to gain confidence in the reliability of the motor and not to worry during intensive use. When choosing an oil, it is recommended to carefully study the instructions and, if necessary, to seek advice from consultants or experienced boatmen. Also do not forget about the existence of fakes, which are most often found in unverified stores. In this case, boat trips will bring only pleasure.
