4-stroke boat motors: features, manufacturers, prices

Everyone who has ever thought about buying an engine for a motor boat, faced the same problem - a large range of products. Among the models of all popular manufacturers it is difficult to look at a copy that can meet the requirements, but at the same time it will have an affordable price.

Today, 4-stroke boat motors are gaining special popularity due to their distinctive advantages over 2-stroke models. However, their range is quite large, and it is not everyone's power to understand all the subtleties of choice.

Distinctions of engines

To give a comparative characteristic of all 4 tacticians can only be compared with 2-stroke motors. The first distinguishing feature of the described models is a more complex design. The cycle of their work consists of four cycles - fuel injection, compression of the combustible mixture, ignition and expansion, exhaust gases. For all this is a complex, harmoniously working system of valves.

But because of the complex system of intake and exhaust strokes, 4-stroke outboard motors require high-quality fuel. But the specific fuel consumption is much lower. On the average, the consumption of a 600-cubic meter capacity of 80 liters. from. Is about 12 liters per 100 kilometers.

Four-stroke engines are more "comfortable" - the level of their vibration is much lower than that of 2T models. This is due to their design. The last advantage is reliability and durability. According to user feedback, the described models serve 2-3 times longer.

Who should choose a 4-stroke motor?

2T models are famous for being able to collect the maximum speed in a shorter period of time. Moreover, the power of such engines is much greater, which is associated with more efficient use of the energy of flammable fuel. In comparison with them, 4-stroke boat motors may seem too "slow".

Indeed, four-stroke models are slower to gain speed, and can not boast of a large number of horsepower. Therefore, they are better suited for those who value, above all, reliability and durability, agrees to a measured journey along the river and does not save time.

Boat Motor Power

Regardless of which unit you choose, your attention should be focused on the correct choice of the power model. If you are going to use a fishing boat, then you are better suited 4-stroke boat motors with 2-3 liters. from. The unit capacity of 30 liters. from. Lovers of fast travel and water skiing.

In addition, it is necessary to take into account the requirements for engine power, which are made by manufacturers of swimming equipment. You can find out this parameter in the technical data sheet of the swimming device. We can not forget that with increasing power, the economy of the installation falls (fuel consumption is increasing).

Outboard motors from YAMAHA MOTOR
