The result? Exceptional performance, durability, and efficiency that make Mercury outboards the top choice for boaters and mechanics worldwide.

Difference between outboard and inboard motors

As the name implies, the main difference between inboard and outboard motors is where they are mounted. An inboard motor is mounted inside the boat, typically at the hull. This layout—also known as a sterndrive (the drive is placed at the stern of the boat)—combines an internal combustion engine with a steerable drive unit under the waterline.

Outboards, on the other hand, are dedicated marine engines that attach directly to the stern of the boat, on the outside hull. Smaller outboard motors are operated by hand with a lever or handle, while larger versions connect to the boat’s steering system. One major advantage of outboard motors is that they are easier to remove from the boat for storage or maintenance. They are also typically less expensive than inboard motors.

How to start a Mercury outboard motor

For most recent 2-stroke and 4-stroke Mercury outboard motors, starting the engine is as simple as tilting the motor down into the water and turning the key like on a car. A carbureted 2-stroke motor, however, may not be as simple. For those models, tilt the engine so that fuel can easily reach the carburetor, then squeeze the fuel pump’s primer bulb until it is firm. While in neutral, advance the throttle up to ⅔, then turn the key and push to choke and crank at the same time. Once the engine has started, release the choke and return to neutral.

How to break in a new Mercury outboard motor

When you get a new Mercury Marine outboard motor, it may be tempting to get out on the water and start pushing it hard. Doing so is a surefire way to damage the motor. To properly break in a new outboard boat motor, follow the instructions in the owner’s manual. Let the motor warm up to operating temperature before any real operation. For the next two hours, vary the motor’s RPMs—typically between 0 and 4500 RPM—and every ten minutes run the motor wide open briefly so it operates across a range of conditions. After these two hours, you can run the motor as you regularly would, but avoid running at wide-open throttle for longer than five minutes at a time.
