It is a general fact that boats and outboards will mainly operate under two types. These are two or four stroke self-sustained engine units. They have their pros and cons, where buyers mostly choose them depending on their planned usage. If you prefer speed driving, two stroke motors will provide easier acceleration. It is also cheaper to purchase boats and outboards operating on two stroke engines while they are easy to resell, as well. Additionally, being less complicated in design, such engines are much easier to maintain and repair. This might be the major factor for many buyers, since their simplicity means less and cheaper maintenance.
However, boats and outboards operating on two strokes motors are not as eco-friendly four strokes engines. Both oil and gasoline are used to lubricate two strokes engines in order to make it run smoother. Their exhaust pipes get rather smoky, where the unburned gasoline might easily contaminate the water. Boats and outboards with two strokes engines are proper for users who prefer ease in speeding. Naturally, with new laws, which regulate the use of less polluting engines, producers are finding various ways to resolve the water pollution problems. They aim to produce two strokes engines, without polluting but also without losing the power and ease of speeding.
When you observe a four stroke boats and outboards, you will find them much quieter. This is not their only advantage, where many people prefer quiet water ride to speed. On the other hand, they are more economical, using less oil and gasoline. Four stroke thrust in boats and outboards is mainly used on riding rivers or lakes. They are heavier in comparison to two strokes motors, but they are a lot friendlier to the environment. If you prefer an easy, slower ride, this will be your choice. However, these engines are more complicated and consequently might require more maintenance and repairs.
People who own boats and outboards of larger sizes will usually use the four stroke engines, more robust and heavier that two strokes ones. Their weight might be too much for lighter vessels, which will usually be equipped with two stroke engines. Four strokes motors are a new version of engines for boats and outboards. Regardless of their higher cost and complexity in design, manufacturers try to make them cheaper and easier to maintain due to their eco-friendly system of operation. However, more and more people decide on for strokes mainly due to low noise, less fuel consumption and their own eco-awareness.
