2020 Yamaha 4 HP F4SMHA Outboard Motor

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. Add to that their efficiency, performance and reliability and these pint-sized powerhouses are perfect for all sorts of light duty, like hopping to the cuddy on a tender. Wherever the day takes you, you can take along a little extra power with an F6, F4 or F2.5 Yamaha Portable.

    Description

    Our 139-cc 4-hp portable outboard mirrors our OHV F6, with a couple less horses. It features the same ergonomic, easy-grip starter handle with a built-in decompression device for effortless starts. The F4 also features a built-in fuel tank with the option of switchable access to an additional external tank for amazing extended range. There’s no stopping this little brute.

    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.
    • Wet Sump: A pressurized oil delivery system that incorporates a compact and durable oil pump to keep all of the moving parts of their Overhead Valve systems lubricated and running smoothly for maximum reliability.
    • Corrosion Protection: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha Portable outboards.
    • Maximum Efficiency: The F6, F4 and F2.5 have a carburetor with a factory-selected setting for maximum efficiency, which helps them achieve a C.A.R.B. Three-Star Rating for Ultra-Low Emissions. Additionally, automatic decompression, built-in auxiliary priming and start-in-gear prevention help make for easier starts.
    Convenience & Control
    • Easy Storage: Yamaha’s F2.5, F4, and F6 feature our Easy Storage Oil Retention System. This pressurized oiling system prevents leaks, enabling on-side storage.
    • Comfortable Control: Incredibly nimble, the F6 and F4 feature 180-degree steering and the F2.5 features 360-degree steering with a dynamically balanced and dampened twist-grip throttle for comfort and convenient maneuverabilty.
    • Portability and Storage: Built-in front and rear handles make these lightweights easy to carry. Resting pads and an easy oil retention system allow for convenient on-side storage without cowling scuffs or oil leakage.
