Yamaha LF150XSA4 Outboard Motor

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

⚠️ Important: Because this engine uses Yamaha’s DEC system, it must be installed and programmed by an authorized Yamaha dealer. Both the outboard and the DEC controls require Yamaha diagnostic tools. DIY installation is not an option.

The Yamaha LF150XSA4 is built for twin-engine boats that need cleaner tracking and better balance on the water. It’s the counter-rotating match to the F150XSA4, and it helps reduce helm pull and keeps the boat more stable when you’re running through chop or squeezing into tight docking spots. With 150 horsepower and a 25-inch shaft, it gives you strong, steady performance without adding unnecessary weight.

Under the cowling is Yamaha’s 2.8-liter inline-four with EFI—a proven platform known for smooth acceleration, reliable starts, and solid fuel economy. The Classic White finish gives the motor a clean, premium look that fits well on modern boats, and Yamaha’s corrosion protection helps it hold up in both saltwater and freshwater.

Frequently Asked Questions

Q: Why pick the LF150XSA4 instead of the standard F150XSA4?

This model rotates in the opposite direction, which balances steering forces in twin-engine setups.

Yes. It integrates fully when rigged with the proper components.

Q: Can it be used as a single engine?

It can, but it’s really designed to work alongside a standard-rotation model for best results.
