Should I Get a Two-Stroke or Four-Stroke Outboard Motor?

Jul. 3 2023 Buying Guide By J&B Cycle & Marine

When you're shopping for an outboard motor, one of the biggest decisions you'll have to make is whether to go with a two-stroke or a four-stroke engine. Both options have their pros and cons, which can make it tough to decide which is right for you. We'll explore the differences between two-stroke and four-stroke outboard motors below and help you make an informed decision.

About Two-Stroke Outboard Motors

Two-stroke motors mix oil and gasoline together to be received by the carburetor or injector, which will then feed the mixture into the cylinder via an intake valve. The exhaust valve opens up at the same time, and approximately 20% of the fuel is released without ever being burned. However, there are also two-stroke engines that have direct fuel-injection, which sprays the fuel into the cylinder with more precise timing while the piston covers the exhaust valve to ensure that fuel isn’t wasted. Two-stroke engines are lighter in weight and more powerful, but they are less environmentally friendly and much louder.

About Four-Stroke Outboard Motors

Four-stroke motors, by contrast, burn pure gasoline using a cylinder to circulate lubricating oil through another system. The gasoline and oil never mix in this type of engine. Four-stroke motors can be more efficient in this regard. Four-stroke engines are also heavier and they are more complex and expensive to repair. However, they are more likely to last longer and run more quietly than their two-stroke counterparts.

The Differences

Here are a few main differences between the two types of outboard motors:

Fuel Efficiency

One of the main differences between two-stroke and four-stroke engines is fuel efficiency. Four-strokes are generally more fuel-efficient than two-strokes, meaning you'll get more miles per gallon of gasoline. This can be especially important if you plan on spending a lot of time on the water, as fuel costs can add up quickly.

Maintenance

Another factor to consider is maintenance. Two-stroke engines have fewer moving parts than four-strokes, which can make them easier and cheaper to maintain. However, they require regular oil changes to keep them running smoothly. Four-stroke engines require more maintenance overall, but their separate oil and fuel systems mean they don't need oil changes as frequently.

Choosing between a two-stroke and four-stroke outboard motor can be a tough decision, but ultimately it comes down to your specific needs and priorities. Consider your budget, usage, maintenance needs, environmental concerns, and other factors to make the right choice for you.
