For outboards in this power range, weight and easy, convenient carrying are important. The Mercury 2.5-6 HP four-strokes are among the lightest outboards in this class. However, a light weight and affordable price are not enough. Every portable Mercury four-stroke is packed with features, from the automatic reverse lock to the convenient integrated fuel tank. These four-strokes undergo the same corrosion-resistance processes as our higher-horsepower products. Quality manufacturing, supported by the largest and best-trained dealer network, as well as the industry's best dealer support and spare parts delivery systems. It is no wonder that boat owners worldwide trust our portable four-strokes.

Packed with features
These small outboards are packed with features. From multi-trim for shallow-water positions (on our F 4 - F 5 - F 6 models) to steering pins with 360° steering (on our F 2.5 - F 3.5 models), you will always find the power and versatility you need to handle any situation. Easy starting thanks to the automatic decompression system, which reduces cylinder pressure during the starting process, requiring significantly less force when starting.

Lightweight champion
Thanks to the low weight and the conveniently positioned large handle for easy transport, powering your boat is no problem. And since these lightweight outboards are subject to our strict testing standards, you also get the same reliability you expect from all Mercury outboards.

Reliable starting
Thanks to an automatic decompression function, the cylinders are reduced in pressure to reduce the pulling force required to start.

Integrated or external fuel tank
The Mercury F 4, F 5, and F 6 four-stroke engines have integrated fuel tanks with an external shut-off valve, as well as a filler neck in the engine cover. On these engines, it is possible to connect an external fuel tank mounted in the boat to increase the range.

Shallow water
Variable trim positions improve performance and enable operation in shallow water.
