Yamaha F150XSA4 Outboard Motor

25-Inch Shaft | Digital Electronic Control (DEC) | Electric Start | Power Trim & Tilt | Classic White

⚠️ Important: This engine uses Yamaha’s Digital Electronic Control system, so it has to be installed and programmed by an authorized Yamaha dealer. Both the outboard and the DEC controls require setup with Yamaha diagnostic tools. It’s not something you can install on your own.

The Yamaha F150XSA4 is a solid option for boaters who want the clean Classic White finish but still need the control and smoothness that DEC provides. With 150 horsepower and a 25-inch shaft, it works well on a wide mix of boats—bay boats, center consoles, and anything else that benefits from sharper throttle response and steadier shifting. DEC makes the motor feel very predictable at the helm, especially during docking or slow maneuvering.

At the core is Yamaha’s 2.8-liter inline-four, which is known for reliable midrange power, good fuel economy, and quiet operation. EFI helps the engine start cleanly and keeps it running smoothly. The Classic White coating isn’t just cosmetic—it holds up well in saltwater, making the motor a good fit for coastal or freshwater use.
