For many consumers, there doesn’t sound like there is much of a different between a two stroke engine and a four stroke engine. The first thing to understand when it comes to the differences between the two is what a stroke actually is. A stroke in an engine is the movement of the piston going up or down. The power stroke is when the gasoline in the cylinder fires.
This is what creates the power that is used to make a vehicle operate. In a two stroke engine, every second stroke is the power stroke whereas every fourth in a four stroke engine is the power stroke. This means a two stroke engine can be considered ‘more powerful,’ which many people consider to be a huge advantage. Just make sure to buy the right mercury outboard oil to maintain your engine properly.
