Yamaha F70LB Outboard Motor

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

The Yamaha F70LB is known for being one of the lightest 70-horsepower 4-stroke outboards on the water. It’s a strong match for bay boats, pontoons, center consoles, and aluminum fishing rigs that need a mix of speed, clean throttle response, and dependable everyday performance. With a 20-inch shaft, remote control setup, electric start, and power trim & tilt, this motor delivers plenty of capability without adding unnecessary weight.

Its inline 4-cylinder 4-stroke engine is quiet and fuel-efficient, and it has the low- and mid-range torque boaters appreciate when getting on plane or maneuvering in tight areas. Yamaha’s EFI keeps starts crisp, throttle response smooth, and fuel use consistent. The power trim & tilt feature lets you dial in your running angle, work through skinny water, or prep the motor for trailering.
