Yamaha F150XSA2 – 150HP In-Line 4 Updated Outboard Motor For Sale

The Yamaha 150 HP Outboard Motor (F150XSA2) is the updated XSA2 version of one of Yamaha’s most celebrated performance outboards — and a top-selling 150 HP Yamaha outboard motor for sale at Boat Engine LLC in New York. Building on the proven In-Line 4 platform that made the F150 a benchmark in its class, the XSA2 designation reflects meaningful refinements to the EFI system, internal component tolerances, and overall engine management calibration — resulting in improved throttle response, more consistent wide-open-throttle output, and enhanced long-term durability over the earlier XSA series. Delivering 150 horsepower at 5500 RPM, the F150XSA2 occupies the critical performance tier between the popular 115 HP class and the heavier V6 offshore engines — making it the ideal single-engine powerplant for 20 to 24-foot center-console fishing boats, walkaround cruisers, and serious dual-console family boats that demand strong offshore capability without triple the fuel bill.

Yamaha’s In-Line 4 architecture at 150 HP is a genuinely distinctive engineering choice — one that produces a powerhead significantly narrower and lighter than competing inline-4 and V4 designs at the same horsepower. This weight advantage directly improves handling, reduces transom stress on single-engine applications, and contributes to better fuel economy at cruise. The updated EFI management system in the XSA2 series delivers precision fuel delivery across the full RPM band — boaters consistently report excellent fuel efficiency at 4,000 to 4,500 RPM cruise speeds, strong hole shots with minimal bow-rise, and a smooth, linear throttle curve that inspires confidence whether you are running an inlet in a following sea or pushing hard to a distant offshore waypoint. For twin-engine applications, the F150XSA2’s compact footprint and precise EFI synchronization make it one of the cleanest-running twin setups in the 300 HP combined output class.

The Yamaha 150 HP Outboard Motor (F150XSA2) comes in the XSA configuration with a 25″ extra-long shaft — the correct specification for most 20 to 26-foot offshore and center-console hulls that require deeper transom engagement for proper anti-ventilation performance at high speeds. Remote controls come standard, ready for full integration with mechanical cable, hydraulic, or electronic steer-by-wire systems.
