Description
Explore the Yamaha Midrange 1.8-Liter F90 Outboard Motor at All Pro Powersports. The Yamaha F90 uses a 1.8-liter, single-overhead-cam four-cylinder with four valves per cylinder, giving it more displacement than many 90 hp rivals. That translates into quick acceleration for aluminum fishing boats, small pontoons and runabouts. Variable Trolling RPM is available through the Command Link tachometer.
