How is running the outboard motor

Any experienced driver knows how important it is to earn extra components and motor mechanisms. The same applies to the outboard motors, which have many fundamental differences, but also require preconditioning. There are different rules for this procedure, but in any case it is important to understand that this is the same necessary part of maintenance, like oil changes with performance testing of individual elements of the machine. Of course, running the outboard motor requires time and organizational costs, but in the future it will provide a more reliable and durable operation of mechanisms. Now it is possible to consider further how the break-in period of the power unit affects the increase in its resources.

The process is useful for the running?

Running-motor elements directly affects three main mechanisms - the crankshaft bearing, gearbox and parts cylinder with piston rings. Immediately it should be noted that running two-stroke outboard provides burnishing rolling bearings. In turn, four models operate on sliding bearings. In both cases, during the break-in creates a small force on the friction, which allows you to initially remove the high voltage to the crankshaft. As for the cylinder with the piston rings, there occurs an optimum range of the gap to meet an acceptable thermal mode. If running allows you to configure the correct running-in of these elements, the service life of the piston will be able to bring to a value close to the maximum.

The nuances of the running gear

The gearbox still raises some doubts in terms of the need to perform burnishing it. Although most manufacturers produce gears from high quality alloys, which do not give the chip during operation, there are exceptions. For example, a boat engine "Mercury" contains the gearbox parts made by powder metallurgy technology. In itself, this speaks in favor of the manufacturer, since this technique refers to the best. But there she is one drawback - the teeth of the elements are different roughness, which can cause unwanted friction already during running. Nevertheless, this does not cancel the general benefit from this event.

Running the motor "Yamaha"

Performing the running motors with geared screw should be carried out for 10 hours the first 10 minutes the unit should operate with a minimum frequency -. Manufacturer recommends the use of idling at high speeds. Subsequent 50 minutes. running the outboard motor "Yamaha" is performed with the throttle a little more open than half - that is, about 3000 r / min. Further two o'clock burn-in must be carried out under the condition already fully open throttle. At this stage the user task is to bring the work of the motor speed to the level when the boat is on plane. After this speed is reduced, the next 7 hours. Conducted at different operating frequencies of the power unit, but so that periods with continued open throttle is not more than 5 minutes. It is important to note that the break-in to use gasoline mixed thoroughly with the oil. Thereafter, the motor will operate in the normal mode and the motor can be refilled with pure fuel, as "Yamaha" injection start optimum performance.

Running "Suzuki" motor

Manufacturer "Suzuki" also recommends that you perform run-in for 10 hours. The first step is to warm the unit, running its operation at idle for 5 minutes. Further 15 minutes should begin operation at low power. During this period, running the outboard motor "Suzuki" and allow work on the transfer, but only at the minimum speed. The first two hours, you can test and control unit, provided the use is not more than half of its maximum capacity. You should also make sure that the number of revolutions should not exceed 3,000 per minute. If necessary, you can open the throttle on a larger range, but only for the purpose of aligning the position of the boat. You must then gradually to minimize the high-speed mode. The following run-hour can be performed at speeds of more than 4000, but it is not recommended to use the high power at full throttle. The rest of the break-in is carried out at any speed - the main thing is not to abuse with an open throttle.

"Mercury" Motor Running

Again, for refueling, use a mixture of gasoline and oil. The recommended ratio of these components is 25: 1, respectively. In this case, there are no strict restrictions on work at different speeds, but there are other subtleties. The fact that the boat engine "Mercury" in the first hours can be run in with the throttle slightly open, but the frequency must be changed. That is important is the dynamic mode of operation without holding a constant speed for more than 2 minutes. But also a manufacturer of motors of this brand cautions against prolonged operation at wide open throttle valve. First-time operation of such regimes should be avoided.

There is also a caveat regarding the work of the water pump. This applies especially to the modes so-called "dry" operation, when running outboard conducted without circulating the water in the intake reducer. Even a few seconds, such work may lead to pump damage or overheating of the power unit.

"Tohatsu" Motor Running

During the break-in fuel mixture is used again, enriched with butter. The optimum ratio, which is recommended by the manufacturer, is 100 ml of the oil component 5 liters of gasoline. This requirement can cause high enough gassing, but fear this is not necessary. After running is completed outboard "Tohatsu", the need to use such mixtures will disappear and normal operation of the exhaust system.

So begins an event with idling, which is supported by 10 minutes. Further three o'clock motor operation permits the number of revolutions from 500 to 3500 with a maximum capacity of no more than half of the total capacity. It is then possible to increase the speed to 4000, with a small increase in power. This period may last for two hours. After the first five hours of running the outboard motor allows the use of full throttle.

Operation after running

As such, the break-in period of the motor mechanism still does not mean that the unit can be used without observing certain constraints. One is the unacceptability of using maximum power without sufficient warm-up. Such nuances should not be forgotten in the process of full operation. Immediately after running outboard necessary to its maintenance, checking filters, dampers, cables and controls. Particular attention is paid to the tightness. The fact that the existence of leaks is one of the most dangerous faults. Actually, these precautions should be carried out not only after running, but before the first start of the motor since its long-term storage.

Conclusion

With regard to the feasibility of a break-in, there are a lot of negative opinions. In many ways, they are reduced to the fact that the break-in period only reduces the service life of the unit, without adding anything to its reliability and durability. Yet in most cases, running the outboard motor shows that the gentle operation of its useful mechanisms. In addition, it is in the process of a break-in, you can familiarize yourself with the boat. In particular, beginners at this stage master work with different trim angles. Immediately after the acquisition of the motor to go on a serious boat trip in any case be reckless. A pre-test will allow to solve several problems, one of which still remains the increase of the outboard motor operating voltage.
