2027 Yamaha Four Stroke Midrange 1.8L F90LB3

$12,680

Description

Meet the 2027 Yamaha Four Stroke Midrange 1.8L F90LB3—a standalone outboard built for boaters who want easy, dependable power without jumping into oversized horsepower. Finished in Yamaha Brown, it brings a classic, purposeful look to the transom while packing modern, marine-ready performance.
At the heart of this Yamaha F90 is a 1.8L fuel-injected, in-line 4-cylinder with 16 valves (SOHC, 4 valves per cylinder). The result is the kind of smooth, usable torque that’s right at home on the hulls this class of engine is made for—think midrange outboard applications where strong push out of the hole and confident mid-range acceleration matter for getting a boat on plane and keeping it there comfortably. With 90 bhp (67.2 kW) at 5500 RPM and a full-throttle range of 5000–6000 RPM, it’s tuned to run where boaters actually spend their time.
Fuel economy at cruise is helped by its fuel-injected design and the fact that it runs on regular gas—so you get efficient, predictable operation without specialty fuel requirements. A 2.15:1 gear ratio is set up to deliver practical propeller authority, helping convert horsepower into real-world thrust for everyday boating, whether you’re running a bay boat, utility skiff, or similar-sized platform that matches a 90-horse outboard.
Built to live in the marine environment, this outboard is salt water capable and uses water (open loop) cooling. For added confidence on the water, Yamaha’s visual/audible alert system and emergency RPM reduction are there to help protect the engine if something needs your attention.
This F90LB3 comes with an electric starter, power trim, and remote steering control, making it a great fit for clean rigging and easy helm integration. The 35-amp alternator supports solid charging capability for onboard electronics. It’s a 20-inch shaft model and weighs 353 lbs (160 kg) dry, a practical balance for many transoms in this power range.
If you’re shopping for a new outboard that delivers smooth four-stroke manners, efficient cruising, and the right muscle for midrange hulls—this Yamaha Brown F90LB3 is ready to power your next season. Warranty coverage applies—contact us for the details and rigging options.
