2-Stroke or 4-Stroke

Before you get ahead of yourself and worry about choosing a brand, you’ll need to figure out some other details first. For starters, do you prefer a 2-stroke or a 4-stroke outboard motor? Many people will tell you right off the bat to go with a 4-stroke. There are scenarios where this is the right choice, but it’s also crucial to note the difference between the two motors. The 4-stroke option burns straight gas via cylinder, which circulates lubricating oil through a separate system. In the process, the gas is never mixed with the oil unless there’s a breakdown.

When it comes to the more traditional 2-stroke model, the mix of oil and gas is received by carburetor or injector directly into the cylinder via intake valve. As this occurs, the exhaust valve is open and 20 percent of the fuel escapes unburned. The direct fuel injection engines spray fuel into the cylinder with precision timing as the piston covers the exhaust so no fuel is lost. At the end of the day, both the DFI 2-stroke and 4-stroke outboard motors provide a level of fuel economy that has significantly improved since the traditional 2-stroke models.

One or Two Motors

Next, you’ll need to decide if your boat should have one or two motors. In offshore fishing applications, you’ll often see dual motors. Many boaters choose this setup because they’re concerned about possibly losing a motor at sea and becoming stranded. Additionally, dual motors also make it easier to dock your boat since the engines have propellers that rotate in opposite directions. Don’t forget that this type of setup will cost more upfront. When deciding between one or two motors, cost tends to be the main concern. If your budget permits a dual motor setup, go for it. If you’re more inclined to simplicity and affordability, one motor will do just fine.

Motor Size

A common misconception is that size determines performance. While this might hold some truth, it’s worth noting that there have been massive improvements since the early days when small motors usually meant disappointment. Nowadays, size still matters in some aspects, but smaller doesn’t automatically mean inefficient. It’s critical to remember not to under-power your boat, either. You won’t be able to enjoy the full potential if you don’t have the right amount of power in your outboard motor. It’s wise to go with the maker’s maximum rating.
