What Is Outboard Motor?
An Outboard Motor Is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft.
Unlike inboard motors, this type of motor is designed to be installed to the outside of the transom, or outside the boat which leaves more room in the interior of the boat. Benefits of outboard motors include a high horsepower to weight ratio, ease of installation and maintenance and extended maintenance intervals.
An important thing to know about outboard motors is that they come in two different versions: 2- and 4-stroke. In the past, the differences between these two models were more significant. However, thanks to advancements in technology, modern-day 2- and 4-stroke motors are much more comparable in reliability, weight, speed and fuel economy.
Outboard motors consist of three main sections. These include:
- Top (outboard powerhead)
- Mid-section
- Outboard lower unit
Let’s take a closer look at each of these sections and how they work:
Outboard Powerhead
The top section of an outboard motor, or the outboard powerhead, is composed of various components that make up a combustion engine. It houses the engine block, cylinder heads, pistons and valves that make the engine run.
Mid-Section
The mid-section of an outboard motor is a metal casing designed to connect the engine to the lower unit. Its main function is to act as a channel for connecting the components of the engine with those in the lower unit.
This section includes a bracket, which attaches the motor to the transom of the boat. This allows for the engine to turn different directions and for the boat to be steered.

The top half of the engine contains the outboard powerhead, which is made up of several different components. The mid-section refers to the middle part of the engine, and the outboard lower unit is located below.
How Does Outboard Motor Works?
The crankshaft turns the main driveshaft running down the long spine of the motor. A small gearbox at the bottom of the driveshaft converts vertical spinning motion into horizontal spinning motion. The propeller powered by horizontally spinning gears powers the boat through the water.
