Small Portable

Yamaha’s smallest Portables, the F6, F4 and F2.5, weigh in at as little as 37 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 an F6, F4 or F2.5 Yamaha Portable.
