Years ago, the choice was clear: When it came to 2 stroke vs 4 stroke outboard motors, 2 stroke won every time. Two stroke motors offered a better power-to-weight ratio, were cheaper to manufacture, ...

The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

When I went to school for engine repair in the 1980s, we studied the differences between two- and four-stroke engine cycles extensively. If you're not familiar with engine strokes, understanding the ...

Any oddball engine is clickbait crack for mechanical nerds, and the most compelling ones purport to introduce an entirely new combustion concept. "Not a four-stroke, not a two-stroke, a revolutionary ...

If you’re shopping for a new fishing boat or an outboard motor to power it, one of the decisions you’ll have to make is between a 2 stroke vs 4 stroke engine. Unless you’re going electric, this choice ...
