Power & Performance
– LIGHTWEIGHT, PORTABLE POWER: They may weigh as little as 37 pounds, but these Overhead-Valve portable outboards are packed with features that create smooth, quiet power. This includes a CDI or TCI ignition system, an optimally balanced crankshaft, a long span mounting system and a labyrinth exhaust.
– ULTRA-LOW EMISSIONS: The Portable F6, F4 and F2.5 are California Air Resources Board (C.A.R.B.) Three-Star Rated for Ultra-Low Emissions and meet federal EPA requirements.
– RECORD SETTING FUEL EFFICIENCY: Small motors use less fuel, but according to the Guinness Book of World Records, the Yamaha F4 actually set a world record for fuel efficiency, traveling 67.27 continuous statute miles on one gallon of gas.
Reliability & Durability
– EASY OPERATION: The F6, F4 and F2.5 feature built-in, see through fuel tanks. The F6 and F4 also feature switchable access to an optional, 3.1-gallon external fuel tank for extended range.
