Yamaha F115LB2 — 115HP In-Line 4 Updated Outboard Motor For Sale

The Yamaha F115LB2 is the updated B2 series version of Yamaha’s globally best-selling 115 HP outboard — and one of the most in-demand 115 HP Yamaha outboard motors for sale at Boat Engine LLC in New York. The “B2” designation signals meaningful engineering refinements over the original F115 platform, including improved electronic fuel injection calibration, enhanced cold-start reliability, and updated internal components that extend service intervals and long-term durability. Delivering 115 horsepower at 5500 RPM through a refined In-Line 4 4-stroke EFI powerhead, the F115LB2 remains the undisputed benchmark in the 115 HP class — the single-engine standard for 18 to 22-foot center-console fishing boats, dual-console family cruisers, and large bay boats across the Northeast.

What continues to set the F115LB2 apart from every competing 115 HP outboard motor for sale on the market is Yamaha’s In-Line 4 architecture — a design choice that produces a narrower, lighter powerhead than V4 configurations at the same horsepower output. This translates directly into better weight distribution on the transom, improved handling and trim responsiveness at speed, and easier single-engine rigging on boats designed around one motor. The updated EFI system in the B2 series delivers optimized fuel delivery across all RPM ranges — resulting in fuel economy figures that consistently beat competing 115 HP outboards at both trolling speeds and wide-open throttle. Boaters running the F115LB2 report strong mid-range torque that loads the throttle confidently, smooth hole shots with minimal bow rise, and a quiet, refined exhaust note that reflects Yamaha’s commitment to in-water acoustics on populated New York waterways.

The Yamaha F115LB2 comes equipped with a 20″ long shaft — the correct fit for the vast majority of 18 to 22-foot center-console and dual-console boats — and is configured for remote mechanical or hydraulic steering and cable throttle/shift control, ready for full helm integration right out of the box. Whether you are rigging a new center-console, upgrading from an older 115 HP 2-stroke or early generation 4-stroke, or replacing a tired engine on a proven hull, the F115LB2 is the most reliable, most efficient, and best-supported 115 HP outboard available today.
