2023 Yamaha Marine F25
Our 432-cc 25-hp portable outboard features a streamlined, portable design and class-leading power-to-weight. While its 25 percent lighter than its previous design, it still packs exciting features like battery-less EFI. Pull-start models can now take advantage of this feature, plus the system is designed with an automatic decompression device to require even less effort for manual starting.
Features may include:- Available for remote mechanical or tiller-handle control
- Only 126 pounds (15” shaft model)
- Available in 15” and 20” shaft lengths and in a High-Thrust design (T25)
- Powerful 16-amp alternator
- Variable Trolling RPM Switch (VTS®) is standard on factory-equipped tiller handles, and available with our Multi-Function Tiller Handle, a Command Link® tachometer or dash mounted VTS switch
- Select models - including 15-inch shafts - now feature a shorter, factory-installed tiller with Power Trim & Tilt and a tilt-up feature for ease in small spaces
