Outboard Motors – 2 Stroke vs 4 Stages

Outboard motors are a popular choice for many boating enthusiasts. They offer a neat way to get power to your boat and they’re easy enough to install on your own. If you’re not exactly skilled in the field, however, you may wonder how long do outboard motors last. Fortunately, there are several things you can keep in mind when you’re shopping around.


Outboard motors are a popular choice for boats for several reasons. They are small and easy to manage. They tend to offer better performance than their four-stroke siblings, which is why they are so popular in smaller boats. New outboard motors (https://www.boatsgalore.com.au/New-Motors) come with limited warranties, but their terms may vary from manufacturer to manufacturer. However, every outboard motor does need to be serviced a bit regularly, so it’s important to purchase from a manufacturer who can offer extended service if you require it.

One of the best things about outboard motors is that they tend to run cleaner than the fuel in a gas boat. While there are a few diesel fuel outboard motors out there, many fuel tanks use Ethanol. Since Ethanol is considered a “plant-based” product, it is different than typical diesel fuel. By running your outboard motors on Ethanol, you’ll be able to save money on gas, save the environment, and generally have a better boating experience.


Because outboard motors tend to run much hotter than the engines in a four-stroke boat, they also have the potential to run longer before requiring repair. Boats with diesel engines will often need to be refilled with fuel at least twice a year. With a high horsepower outboard motor, you should be able to get three or four hours of use out of it before you will have to replace the engine.

The higher the powered outboard motors, the greater the fuel efficiency. The fuel efficiency of outboard motors is determined by the stroke/ rpm ratio. The greater the RPM, the greater the fuel efficiency. Two-stroke outboard motors, however, tend to be less fuel-efficient than four-stroke outboard motors. Many manufactures have also designed their outboard motors to be much more fuel-efficient than conventional two-stroke motors.

Despite their advantages, two-stroke engines do have some disadvantages. Typically, they are not as powerful as outboard motors which tend to offer greater horsepower. They also cost more to manufacture since they need two-stroke engines. There are also costs involved in switching from one engine to another, which can reduce the operating profit margin. In general, however, two-stroke engines are less expensive to purchase than convention four-stroke engines.

One of the most popular and common features of outboard motors is gas injection. The fuel injection system is a very sophisticated feature of outboard motors which allows for the mixing of fuel into the engine at different stages of engine operation. This feature, which was invented by German technicians in the late 1950s, is a necessity in that without it there would be a serious reduction in the life span of an outboard motor. The gas mixture is injected first into the air filter and then into the combustion chamber where the fuel is ignited and the combustion process begins. With a lack of fuel injection, the engines could run on nothing but water and would be incredibly inefficient.

There are two different types of fuel injections for outboard motors. The first type is called the conventional fuel injection system, which uses a small amount of fuel in the combustion chamber before it is ignited and used. The other is known as the negative start fuel injection system, which injects fuel directly into the combustion chamber when the engine fires. No water is involved, making this a much more efficient option for use with two-stroke engines.
