Maximum power
The maximum operating power of the outboard motor, expressed in kilowatts.
The practical value of motor power is described in detail in “Maximum power" is higher. Here we note that the kilowatt (derivative of watt) is just one of the units of power used in fact along with horsepower (hp); 1 HP ≈ 735 W (0.735 kW). Watts are considered the traditional unit for electric motors (see "Engine Type"), but for a number of reasons, outboard motor manufacturers use this designation for gasoline models as well.
Generator system
Possibility to use a petrol engine generator(see "Engine type") to power an external load.
The generator is an indispensable element in the design of any petrol engine — it is responsible for creating the spark necessary for ignition. However, not every outboard motor has the ability to power an external load from this generator — therefore, if such an opportunity is important to you, you should choose a model where it is directly stated. And
the generator system can come in handy, first of all, if you plan to use additional equipment on the boat — power from the generator is in a number of ways more convenient than from autonomous batteries, and it is for it that many navigation systems, echolocation, radio communications and other instruments and equipment are made . In addition, if necessary, devices outside the boat can also be powered from the generator — for example, a starting charger for a car.
Maximum current strength
The highest current that the generator system installed in the outboard engine is capable of delivering (see above). The characteristics of the load that can be connected to the generator depend on this indicator: its total current consumption should not be higher than the maximum current of the generator, otherwise the latter will work with overload, which is fraught with malfunctions and even accidents. Also, this information is useful if you plan to use the generator to charge batteries (car or boat): each battery has its own charging current, and the power source must match them.
Recommended fuel
The type of gasoline recommended for use in an internal combustion engine outboard (see "Engine Type"). In fact, this paragraph indicates gasoline with the lowest octane rating that is allowed to be used in the engine; higher rates are allowed, lower ones are highly undesirable, if not outright prohibited.
The octane number is an indicator that determines the resistance of a particular brand of gasoline to detonation (self-ignition during compression in the cylinder). Detonation is a very undesirable phenomenon, because. it leads to an increase in engine loads simultaneously with a decrease in its power and an increase in the amount of harmful substances in the exhaust gases. And this phenomenon occurs in cases where the engine uses gasoline with lower octane numbers than those for which the unit is designed.
Automobile gasoline, which is also used for refueling boat engines, is marked with the AI or RON index; the first option is used in the characteristics of east european motors, the second — in foreign ones. However, in both indexes, the number after the letters means the octane number. The higher this number, the more demanding the engine is on fuel quality. Thus, for example, a unit under AI-92 will be able to work normally with AI-95, but AI-90 or AI-87 cannot be filled into it. "Record holders" for unpretentiousness today are engines that can work even on the AI-76; but they are a rare exception to the general rule.
