Yamaha F90B four-stroke is a good fit for boaters who own smaller boats. The new Yamaha F90B is lighter, smaller and more powerful than its predecessor. Furthermore, It is set to make an impact squarely in that midrange space. The new Yamaha F90B is based on a 1.8-liter in-line ­­four-cylinder powerhead. The Yamaha F90B four-stroke uses a single overhead-cam head with four valves per cylinder. This design might compromise performance a bit but, it is equally important to note that, it makes it less complex (and thus less expensive). It is also lighter in weight and more compact than the double cam. It now leads the 90-horsepower four-stroke class in torque and acceleration. All that means this Yamaha Outboard Engine will be a terrific choice for a variety of boats. This is suitable for the inshore fisherman in particular.

Power and Performance

•The new Yamaha F90B four-stroke is faster and has the quickest four-stroke, 90-horspower
acceleration
• Like the successful F70 before it, the F90B employs a single overhead
camshaft to drive four valves per cylinder, thereby saving weight
while increasing volumetric efficiency – and making more power. Also
• Thirteen pounds lighter than its predecessor: 353 pounds versus
366 pounds (F90LA)
• More displacement means more torque. The new F90B displaces
1.8 liters versus 1.6 liters over its predecessor. Also,
• The new F90B still runs on regular 87 octane gasoline.

Convenience and Control.

The Yamaha F90B four-stroke is not just the quickest. Also  it is quiet, which means a better time
