Engine Info & Specs

Not your typical portable outboard engine, the 2017 IBEX Innovation Award winning F25 is one Yamaha's most powerful protables yet, boasting a manual start and a tiller handle. The F25SMHC's single-overhead-camshaft, two-cylinder design offers a power to weight that puts this outboard engine at the top of its class. In fact, this previously midrange four-stroke outboard is now so light, it's jumped to Yamaha's portable family.

Like the Yamaha F15, and F20, the F25SMHC offers Yamaha's signature portable advantages, like an oil-retention system for leak-free, on-side storage capability, carry handles, and resting pads. So whether you're headed duck hunting with a jon boat or on the way to a lake cottage and your 14-foot aluminum boat, your Yamaha portable is ready to go.
