Yamaha’s high-powered portables are redefining the expectations for portable horsepower. Their single-overhead-camshaft, two-cylinder designs create power to weight that’s not only eye-opening

Our 432-cc all-new 20-hp portable outboard-built on the same award winning platform as the F25 and sharing its SOHC in-line design and streamlined intake manifold, delivers solid power. Not only that, but it’s one of the most fuel efficient in its class. At just 126 pounds, it’s suitable for lightweight craft such as aluminum fishing boats, tenders and inflatables.
