Yamaha 90HP | F90LB

Long Description:

The Yamaha 90HP (F90LB) is a masterclass in modern midrange engineering. Moving away from heavy, over-complicated designs, Yamaha utilizes a 1.8-liter, four-cylinder platform that drastically reduces weight while expanding displacement. The result is a highly efficient 16-valve, Single Overhead Camshaft (SOHC) layout that delivers a richer torque band and exceptional hole shot response without sacrificing fuel economy.

Built for versatility, the F90LB is the perfect power option for a massive variety of coastal, aluminum, and fiberglass hulls. It is controlled by an advanced microprocessor Engine Control Module (ECM) that balances peak performance with legendary reliability. With features like Variable Trolling Control and a massive 35-amp alternator, it offers modern tech amenities alongside rock-solid utility.

Models Available:

• F90LB: Standard 90HP four-stroke with a long shaft (20-inch). The quintessential midrange performer offering an optimal blend of agility, torque, and class-leading weight savings.

• F90XB: Extra-long shaft variant (25-inch). Shares the identical SOHC 1.8L powerhead but features an extended midsection to accommodate deeper transoms and rougher water configurations.
