Description
Yamaha 6HP F6SMHA Portable 4-Stroke 15in
The Yamaha 6HP F6SMHA is an agile 139cc single-cylinder outboard featuring a 15-inch short shaft, engineered for maximum portability and ease of handling on small tenders and inflatable boats. This SOHC engine features Yamaha’s innovative “three-way” storage system, which allows the motor to be stored on either side or the front without the risk of oil leakage. Its mechanical soul is defined by its smooth, quiet operation and impressive fuel economy, making it a favorite for solo anglers and recreational boaters seeking a dependable, low-maintenance power solution.
Focused on superior operational durability, the F6SMHA utilizes high-grade marine alloys and specialized anti-corrosion coatings to safeguard against oxidation. The engine features a large carry handle and a 180-degree steering radius for exceptional maneuverability in tight quarters. Routine maintenance is simplified by the easy-access oil fill and a dual fuel supply system that includes a built-in 1.1L tank and a connection for an optional external tank. This model includes a stable 6-amp alternator to support basic navigational lighting and small electronic accessories.
