2023 Yamaha 4HP

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.

The lightweight F6, F4, and F2.5 portable outboards weigh as little as 37 pounds yet deliver smooth, quiet power through Overhead-Valve design with CDI or TCI ignition, optimally balanced crankshaft, long span mounting system, labyrinth exhaust, electronic ignition, thermostatic cooling, and 180-degree steering, with the Guinness World Record-setting F4 achieving an incredible 67.27 continuous statute miles on one gallon of gas. Featuring built-in see-through fuel tanks with switchable access to optional 3.1-gallon external tanks on the F6 and F4 for extended range, wet sump pressurized oil delivery system for maximum reliability, Phaze Five™ five-layer anti-corrosive paint with YDC-30 proprietary alloy, and factory-selected carburetor settings that achieve C.A.R.B. Three-Star Ultra-Low Emissions rating with automatic decompression, auxiliary priming, and start-in-gear prevention for easier starts, these engines offer Easy Storage Oil Retention System for leak-free on-side storage, incredibly nimble 180-degree steering on the F6 and F4 or 360-degree steering on the F2.5 with dynamically balanced twist-grip throttle, plus built-in front and rear handles with resting pads for easy portability and convenient storage without cowling scuffs or oil leakage.
