Yamaha F25 2024: The Lightest 25HP Outboard on the Water
The 2024 Yamaha F25 redefined the 25HP class: 25% lighter than its predecessor, it claimed the title of lightest 25-horsepower outboard available. Its 432cc SOHC in-line twin runs battery-less electronic fuel injection — EFI starting and crisp, reliable running with no battery required on pull-start models, thanks to automatic decompression. Buyers choose pull or electric start, tiller or remote configurations, and select 15″ shaft models add Power Trim & Tilt with a convenient tilt-up feature. Yamaha even offers it in pearlescent white, matte brown, or classic gray. As the flagship of the 25HP outboard class, the F25 blends big-water capability with genuine portability.
