Yamaha F90LB Outboard Motor

20-Inch Shaft | Remote Control | Electric Start | Power Trim & Tilt | Gray

The Yamaha F90LB is a light, easy-running 90-horsepower four-stroke that works well on a wide range of mid-size boats. It uses Yamaha’s 1.8-liter inline-four, which has a reputation for smooth power, good torque, and very reasonable fuel use. Boats like center consoles, pontoons, flats skiffs, and aluminum fishing rigs tend to handle really nicely with this motor because it doesn’t add a lot of weight but still gives you plenty of push when you need it.

With a 20-inch shaft and remote control steering, it fits most standard-height transoms. The engine runs quietly, starts easily, and trims cleanly, and the EFI system does a good job keeping the fuel burn predictable whether you’re idling around or making a longer run.

Frequently Asked Questions

Q: What’s the difference between the F90LB and F90XB?

Same power and performance — the only real difference is shaft length. The LB uses a 20″, the XB uses a 25″.

Q: Does it come with rigging or a prop?

No. Controls, propeller, and rigging components depend on the specific boat setup and are purchased separately.

Q: Can this engine run digital gauges?

Yes. It’s fully compatible with Yamaha’s Command Link® system, so you can go digital or stick with analog gauges.
