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.
Power source
The supply voltage supplied by the generator system installed in the outboard motor.
Almost all such systems work with a voltage of 12 V — this is a standard widely used in modern automotive and water technology, it is under it that the electrical systems of the engines themselves, and electronic devices for cars and boats are made. There are practically no exceptions to this rule.
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.
Fuel system type
The type of fuel system installed in the gasoline outboard motor (see "Engine type"). The key difference between modern fuel systems is the way the fuel is injected. It can be like this:
— Carburetor. The simplest fuel injection system, the operation of which is based on the suction of fuel by the air flow that enters the cylinders during the intake phase. Carburetor engines are simple both in design and maintenance and repair, they are inexpensive and undemanding to fuel quality. On the other hand, they are more difficult to start than injection ones, have less power, consume more fuel and emit more harmful substances into the atmosphere. Therefore, this option is typical mainly for relatively simple models of the primary and middle class.
— Injector. A system that involves forced fuel injection using injectors. Injectors can have a different design and format of work, they can involve injection into the intake manifold or directly into the cylinder. However, all such engines are considered more advanced than carburetor ones, due to a number of advantages. In particular, injection systems increase power, improve dynamic performance and at the same time reduce fuel consumption and the content of undesirable impurities in exhaust gases; in addition, the engines are easier to start. On the other hand, injectors are expensive, require high-quality fuel and are very difficult to repair — it is almost impossible to repair such a system outside a service cen...tre without special skills and tools.
Weight
The total weight of the outboard motor. This parameter is indicated, usually, only for the unit itself, without taking into account the fuel in the tank and the tank itself (if it is external, see "Fuel tank"), as well as additional equipment. Motor weight data can be useful in order to estimate the overall balance of the boat and the change in its payload capacity.
