Yamaha 2.5 HP Outboard Motors
SKU: F2.5SMHB
Yamaha’s smallest Portables, the 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 F2.5 Yamaha Portable.
Our 72-cc 2.5-hp portable outboard is the smallest motor on our roster, but it still packs a punch. Completely redesigned, it’s even more portable, easier to store and clean burning.
- Available for tiller-handle control with forward-neutral shifting, 360-degree steering and an ergonomic twist-grip throttle
- Only 37 pounds (15” shaft model)
