Yamaha Outboards Portable Four Stroke F4

The sun just broke the horizon, but your day began hours ago-the second you started your trusty Yamaha Portable. Maybe you’re skimming the marsh in a jon boat during duck season, pushing a sailboat ’til the wind kicks up or hopping to the cuddy on a tender. Wherever the day takes you, these nimble, lightweight, efficient portables are up for the ride. Available in a range of horsepower from the F20, to the F2.5, including the redesigned F8 with 7.5 percent more displacement, these 1- or 2-cylinder dynamos provide big performance in streamlined designs.
