2027 Yamaha Four Stroke In-Line F150LD

Meet the Yamaha Four Stroke In-Line F150LD in classic Yamaha Gray—a standalone outboard that’s all about turning everyday boat days into “let’s do one more run” days. With 150 bhp (111.9 kW) at 5500 RPM from a 2.7L (2670cc) inline four, this engine lands in that sweet spot for powering a wide range of mid-size hulls that want confident acceleration, a strong cruising pace, and enough punch for loaded weekends without feeling overworked.
The personality comes from its modern inline-four design: DOHC with 16 valves (4 per cylinder), fuel injection, and a 9.0:1 compression ratio designed to run on regular gas. Translation: smooth, responsive throttle and efficient operation at cruise—ideal for owners who rack up hours and prefer more time on the water and fewer fuel stops.
Built for real marine duty, it’s water-cooled (open loop) and explicitly salt water capable, with a visual/audible engine alert system and emergency RPM reduction to help protect the powerhead when conditions get demanding. The 35-amp alternator supports onboard electrical needs while you’re underway.
This F150 spins a prop through a 2.00:1 gear ratio, pairing well with hulls that benefit from authoritative midrange pull and controlled, confident handling. The power trim makes it easy to dial in running attitude for changing loads and water conditions, and remote steering control integrates cleanly with a rigging setup on typical center consoles and similar layouts.
Sized for a standard transom, this model carries a 20-inch shaft and a dry weight of 509 lbs (231 kg). Starting is simple with an electric starter, and wide-open operation is designed around a 5000–6000 RPM range.
If you’re after a versatile, modern four-stroke with practical power, efficient cruising manners, and salt-ready confidence—finished in timeless Yamaha Gray—this Yamaha F150LD is ready to be the heartbeat of your next rig. Warranty coverage: see dealer for details on applicable Yamaha warranty for this new engine.
