115hp
Yamaha's 115hp doesn't just reset the benchmark — it picks it up, moves it to the horizon and invites the rest of the class to try and catch up. Agile, smooth and deceptively strong, it delivers the kind of effortless versatility that makes every boat feel that little bit better than it did yesterday.

Before choosing
Verify the boat manufacturer’s permitted power range, transom height and shaft length, engine and rigging weight, steering and control compatibility, electrical load, propeller selection and the exact variant code before ordering. For twin or multiple-engine installations, confirm steering and control-system requirements as a complete package.
FAQ
- Is this the same as another Yamaha model with similar horsepower?
- Not necessarily. Yamaha can offer different families, control systems, shaft lengths, rotations or duty-oriented variants at a similar output. Compare the full specification rather than horsepower alone.
- What should be verified before installation?
- Confirm shaft or mounting configuration, steering and controls, electrical requirements, propeller selection, weight and the exact model or variant code.
