The outboard motor is one of life’s modern miracles, allowing men and women to easily transport themselves across water without the use of the wind or a large crew to help. Mercruiser is dedicated to helping people get the most out of their marine engine. For years people have entrusted Mercruiser parts to keep their boat running strong.

If you’re new to boating, though, you may be at a loss for what parts you need. You might not even know how your engine works. So let’s solve that problem right now.

When you’re talking about personal watercraft, like a speedboat, you’re almost always talking about an outboard motor. These have become the industry-standard. The engine’s operations are all self-contained, meaning outboard motors can easily swapped off one boat and onto the back of another. Even their steering is linked directly to the motor as a tiller sticks into the boat and allows the user to aim the propulsion in various directions.

For the most part, these engines work the same as the one in your car. Gas is the fuel used, except instead of a battery, most outboard motors run on a manual start much the same way as a lawnmower. Once started, the propulsion from the gas moves the propeller so forcefully that it can actually move the boat and its contents.
