Outboard engines fall into two main categories; 2 stroke and 4 stroke outboards. Both types have their advantages and disadvantages and the type you pick will depend on the intended use. This guide will help you choose which outboard engine is best for your type of boat.
2 Stroke Outboards
2 stroke engines are lighter and faster so when speed and acceleration are required, this would be the engine of choice. 2 strokes are also generally cheaper and keep their value better when it comes to resale. As 2 stroke engines have been around for almost 80 years, parts are readily available, making repairs easy. Also, the design on these engines is less complex than a 4 stroke, meaning problems are less likely to arise.
There are some disadvantages to the 2 stroke engine. 2 stroke engines are more pollutive than 4 stroke engines so they are not so kind on the environment. Their engines are lubricated by the oil that is mixed into the gasoline, meaning the exhaust is smoky and contains unburned oil, which in turn pollutes the water.
With new regulations, outboard manufacturers are looking to find new ways of producing the same power with less pollution.
Some 2 stroke outboard engine manufacturers include Mercury, Nissan, Yamaha and Evinrude.
4 Stroke Outboards
4 stroke engines are quieter, smoother and more economical. Heavier with slower acceleration, they are normally chosen for lakes and rivers. With less pollution and smoke they are also kinder to the environment. If you’re after a quieter, smoother ride, then the 4 stroke outboard is the better choice.
4 stroke outboards are more complicated with more parts so they often require repairs more often. When a repair is required it is usually more expensive and parts are limited.
4 stroke outboards are generally heavier than 2 stroke outboards, so if you own a smaller boat it may not be able to hold the weight of a 4 stroke engine.
