Yamaha 6 / 4 / 2.5 HP
Yamaha’s smallest Portables, the F6, F4 and F2.5, weigh in at as little as 37 pounds, with streamlined overhead-valve, one-cylinder designs. Their light weights, combined with built-in carrying handles, resting pads and an oil-leak prevention system for on-side storage capability create true portability.
Make an appointment with Tom Ross to come in and see these motors in person.
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.
The Portable F6, F4 and F2.5 are California Air Resources Board (C.A.R.B.) Two-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.
