Yamaha F25 2026: The Newest Edition of the Lightest 25 on the Water
The 2026 Yamaha F25 is the latest factory release of the engine that reset the 25HP class — 25% lighter than its predecessor and still the lightest 25-horsepower outboard available. The 432cc SOHC in-line twin runs battery-less electronic fuel injection for instant, choke-free starts even on battery-free pull-start models (with automatic decompression easing the pull). Choose pull or electric start, tiller or remote rigging, and Power Trim & Tilt with tilt-up on select 15″ shaft models — in pearlescent white, matte brown, or Yamaha gray. The definitive flagship of the 25HP outboard class.
