The motor on the boat 2 stroke and 4 stroke: what to choose?

It has not ceased the debate about what type of outboard motor is better for a motor boat – two-stroke or four-stroke. To answer the question, it is necessary to understand the advantages and disadvantages of both motors, as well as to highlight important operating features.

Main characteristics of two-stroke and four-stroke motor

Compare two-stroke and four-stroke engines should take into account the basic performance:

- Power and dimensions. At approximately the same power, the size of a two-stroke engine, the duty cycle of which includes a couple of bars, more compact. The size of the motor is an important indicator for those who have limited space and can not allocate space for storage of the overall four-stroke unit, which also requires special conditions of transportation in a certain position, so that the oil does not flow out.
- The weight of the motor plays a significant role when installed on a small inflatable boat. The heavier the motor, the more you should load your nose. Due to the simplicity of the design and some other features, two-stroke motors are lightweight.
- Fuel consumption. The complexity of the design of the four-stroke engine has a positive effect on fuel consumption, which is minimized. Two-stroke engines in terms of fuel economy lose significantly, consuming more gasoline than four-stroke models.
- Noise level. Two-stroke motors operating at medium and low speeds create a significant level of noise. The four-stroke engines, not running at full power, make a small noise that spreads in the" right noise spectrum " without causing discomfort.
- Service life. To check the durability of the engine, it will have to be continuously operated until it fails, which is initially impossible. Theoretically, it can be argued that the four-stroke units have a greater working life, but this engine requires expensive maintenance and repair due to the complex design.

Which motor is better?

It is difficult to clearly answer the question, what type of engine is better. The choice should correspond to the individual characteristics of the buyer.

Two-stroke engines are lightweight, easy to maintain and repair. Such a motor can be easily transported by car and stored in the garage, using for infrequent swims for short distances.

Four-stroke engines are characterized by low fuel consumption, do not require frequent oil change, are low noise, more environmentally friendly. But this motor is quite expensive, has large dimensions and requires a professional approach to maintenance and repair.

Statistics show that the sales are leading cheap two-stroke engines with a capacity of 5-15 HP. Given the tightening of requirements for environmental engines, with the necessary amount of money, you can pay attention to the four-stroke engine, which is ideal for frequent use in long-distance travel.
