Our buying guide reviews the best 4-stroke outboard motors on the market so you can make an informed decision. The following features are included on most 4-stroke outboard motors and guide you in the direction of the perfect motor for your boat.

Fuel Intake

4 stroke outboard motors need to hold a certain amount of fuel in order to keep running for a long time. Built in fuel take volumes are generally around 1 – 1.2 liters and this will determine how long your motor will run for before needing a refill. They type of fuel which the 4-stroke outboard motor burns is usually unleaded gasoline, and specific outboard motor oil is used by the engine.


Power output varies for each 4 stroke outboard motor. The maximum output is around 3KW on most motors, but this can vary. It is worth checking all of the electrical details of the motor to ensure its compatibility with any other outboard gear.


4 stroke outboard motors vary the speeds they are capable of. When it comes to speed, there are two sets of numbers to look out for. Firstly, the idle speed will tell you the rotational speed the motor runs at when it is idling, or when the throttle is not depressed. Secondly, the maximum speed will tell you how the rotational speed when the motor is at its limit. Faster isn’t always better of course, as high speeds generally burn more fuel.

Safety Features

4 Stroke Outboard Motors come with a number of features to improve reliability and safety. Steering which is capable of rotating 360 degree is common, and allows for easy reversing. CDI ignition systems make starting the motors easy. Air cooling systems should always be installed to prevent overheating when out boating.
