There are plenty of good reasons these outboards rule the water. Start with no-worry reliability. More low-end torque for excellent acceleration. Increased fuel economy and outstanding overall performance. Enhanced fuel injection (EFI models) for boosted efficiency. A robust electrical system with a high-output alternator to keep batteries charged and fishing electronics humming. They have everything you need, and nothing you don’t.

High-displacement, four-cylinder, single-overhead-cam design delivers optimum power and a smooth ride. Great for aluminum tiller, aluminum console, inflatable rigid hull (RIB) and soft hull, watersports, and fish & ski boats.
