Outboard engines are an important component of any boat. It can be said that without these engines, your boat will lack fun and excitement. These engines mainly consist of gasoline-powered spark ignition, internal combustion engines. They are used mainly for marine propulsion in almost all types of boats. Outboard engines are attached to the boats so as to propel them through water. An outboard motor engine consists of three major components and these are gear case assemblies, power head as well as the midsections. The gear contains the propeller, transmission and drive shaft, whereas the power gears consists of internal combustion engine that is required to move the boat forward. The midsection of these engines consists of the tilt/trim mechanism, housing assemblies and steering etc. Outboard engines are usually of two types, which are 2 stroke as well as 4 stroke engines. Both of them have got their own benefits and drawbacks. It is true that nowadays four stroke engines are more popular but still you will find many takers of two stroke outboard engines. 2 stroke outboard engines are much faster and lighter than the 4 stroke ones. They are also cheaper and their value is much better. Since the design of 2 stroke outboard engine is much less complex, you will hardly find any problems with them. People question the pollution levels emitted from these engines; however everything has got some drawbacks. Moreover, the manufacturers are now using sophisticated technologies so as to make these motors more efficient and reduce the pollution levels. A 2 stroke outboard engine is one which completes the entire process cycles in just one revolution of the crank shaft. This is achieved by using the starting of compression stroke and combining it with end of the combustion stokes. Due to this mechanism, these engines provide high specific power. The 2 stroke outboard engines can easily be arranged to start and run in either direction with good design and they have been built to do it. The engines which are not designed to run in the reverse direction can also be used to do it, however it might cause some internal damages and this practice should be avoided as far as possible. This is mainly because of piston pin effects or piston throw effect, a design feature which reduces the piston slap. Even with some drawbacks people love to try 2 stroke engines simply because they are fun to ride. For past few years, four strokes bikes have dominated the market to great extent, but there is something about 2 stroke motors which are not letting them die. However, with technology being improved there are many ways to infuse power and cause less pollution in these engines. There are multiple ways of these engines being improved. Companies are experiments with crankcase volume, cylinder porting, changing exhaust pipes so as to make them more efficient and performing. To the adventurous outdoors enthusiast, we bring 2-Stroke Outboards. Brought to you by the site with Boats for Sale.
