Authorized Yamaha Outboard Dealership
Yamaha’s 4hp portable outboard motors weigh in at as little as 59 pounds. They feature streamlined overhead-valve, one-cylinder designs. The motors’ lightweight construction, combined with built-in carrying handles, resting pads, and an oil-leak prevention system for on-side storage capability, make them truly portable. Furthermore, their efficiency, performance, and reliability make these small but powerful motors perfect for a wide range of light-duty applications, such as traveling to the cuddy on a tender. Wherever your adventures take you, you can bring along extra power with a Yamaha Portable Outboard.
Yamaha’s 139-cc 4-hp portable outboard mirrors their OHV F6, with a couple of fewer horses. It features the same ergonomic, easy-grip starter handle with a built-in decompression device for effortless starts. The F4 also features a built-in fuel tank with the option of switchable access to an additional external tank for an amazing extended range. There’s no stopping this little brute.
