2027 Yamaha Four Stroke In-Line DEC F150XSA4

Bring new life to your transom with the 2027 Yamaha F150XSA4 Fourstroke outboard—finished in Yamaha Classic White for that clean, timeless look that matches everything from modern bay boats to hardworking center consoles. This is an engine-only listing (not a complete boat), built for owners who want reliable punch, smooth manners, and day-after-day confidence on the water.
At 150 horsepower (111.9 kW) turning up to 5500 RPM, this 2.8L in-line four is a sweet-spot power choice for a wide range of mid-size hulls that need strong acceleration without stepping up to bigger, heavier blocks. The 2785cc displacement and 16-valve DOHC design help it pull with authority when you’re climbing onto plane with a crew aboard, then settle into an efficient cruise when the day turns into a long run across the bay or down the coast. And because it runs on regular gas, you can fuel up easily and keep operating costs in check.
This F150 is fuel injected, which helps deliver crisp starting and consistent response whether you’re easing through a no-wake zone or rolling into the throttle to beat weather back to the dock. Cooling is water (open loop), and it’s salt-water capable—exactly what coastal boaters want to see when the tides, spray, and seasons are part of the routine.
Rigging-wise, this model comes in a 25-inch shaft length and is set up for remote steering control, making it a strong fit for many popular transoms that call for a 25" outboard. A power trim system makes it easy to dial in running attitude for changing loads and sea conditions, while the 2.00:1 gear ratio keeps the power going to the propeller where it counts.
On the peace-of-mind side, Yamaha’s visual/audible engine alert system and emergency RPM reduction are there to help protect your investment if something needs attention—so you can focus more on the horizon and less on the gauges.
If you’re looking for a new Yamaha Fourstroke that balances real-world torque, practical cruise efficiency, and proven outboard simplicity in a sharp Yamaha Classic White package, this 2027 F150XSA4 deserves a spot on your boat. Warranty coverage varies—contact our marine team and we’ll confirm the current Yamaha warranty details for this engine.
