Outboard motors provide power for a huge array of vessels, from small fishing boats to large yachts. With so many options available, a basic understanding of these motors and how they work may help you choose the best option for your boat. Here’s a guide. 

What Is an Outboard Motor?

An outboard motor is a self-contained system that uses a propellor to push boats forward and steer through the water. It’s normally installed at the back of a boat, and some large vessels even have multiple motors to provide extra power. Unlike inbound motors, which are contained within the vessel itself, outbound motors are clearly visible outside the main structure. 

How Do They Work?

Outbound motors connect to a fuel tank that injects gasoline into a cylinder, where it is ignited. The burning fuel expands to provide power to move a piston toward the crankshaft, which is what starts the spinning motion of the motor. 

This movement powers the propellor, which creates a circular motion in the water to move the boat forward. The motor can also turn in either direction to steer the boat. Some motors are turned manually, while others connect to a steering wheel using hydraulic lines. 

How Do I Choose One?

If your boat needs a new motor, choose one that has enough power to propel the entire weight of your boat. Boat manufacturers usually provide a recommended power range. Go with the maximum rating for your boat, or slightly higher, to be sure it can support the entire hull capacity, even if your boat is full of people or equipment. 

For example, a small fishing boat may recommend a motor with 12.5 horsepower, so you may opt for a slightly more powerful option with 15 horsepower. Additionally, some boat owners install multiple motors, but this is most common in offshore fishing boats or those that want a backup plan just in case the main motor malfunctions while far from shore.
