Outboard Motor Anatomy: Part One

The two-stroke v. four-stroke debate is an ongoing point of contention between boat owners around the globe. While four-stroke engines certainly have their advantages, two-strokes are ideal for small watercrafts. In the next couple of days, we will be going over the various elements of the two-stroke engine and in what ways it is superior to the four-stroke.

When comparing the two, the most discernable difference for most people is how you mix the gasoline and outboard motor oil. In a two-stroke engine, the oil and the gasoline are mixed together, whereas they are held in separate compartments in a four-stroke. This design makes the two-stroke simpler but provides better lubrication to the four-stroke.
