Understanding How Outboard Motors Work

It is easier to learn how outboard motors work first before debugging. Outboard motor is a self-contained propulsion unit located at the back of a boat, usually composed of:

• Internal combustion engine
• Gearbox
• Jet drive or propeller

Types of Outboard Motors

There are two general types of outboard motors:

• 2-Stroke Engines – Light and strong but need oil mixed with fuel.
• 4-Stroke Engines – Quieter, efficient, and eco-friendly.

We stock 2-stroke and 4-stroke Yamaha, Mercury, Honda, and Suzuki outboards of all the major brands and sizes to fit boats of all sizes.
