4 Stroke Johnson Outboard MotorThe decision to purchase an outboard engine is getting more selective as technology improves. As of now the majority of consumers are faced with several options when deciding upon what kind of outboards will best suite them. The number one factor lately is whether to purchase a new or used two stroke or four stroke engine.

2 Stroke Mercury Outboard EngineWhen faced with this decision you must prioritize several features that are prevalent in each motor. For example, two-stroke motors are lighter, faster (in most cases) and less expensive. Four-stroke motors are cleaner, smoother, and more economical. Many people who run in lakes and rivers prefer 4 stroke boat motors because they make great trolling motors and meet the 2006 EPA mandated requirements. Others prefer 2 stroke engines when the need for top end performance and acceleration takes precedence. This is not to say that two-stroke engines cannot troll or four stroke motors are not fast. It's just a matter of preferences, features, and benefits that attract customers. Regardless of what you choose to purchase, if you use due diligence and do your research you cannot go wrong, Below is a table of pros and cons for both motors:
