Yamaha’s 4hp portable outboards weigh in at as little as 59 pounds, with streamlined overhead-valve, one-cylinder designs. Their light weights, combined with built-in carrying handles, resting pads, and an oil-leak prevention system for on-side storage capability, create true portability. Add to that their efficiency, performance, and reliability, and these pint-sized powerhouses are perfect for all sorts of light-duty, like hopping to the cuddy on a tender. Wherever the day takes you, you can take along a little 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.
