Yamaha Outboards 4HP F4SMHA

Yamaha Outboards 4HP | F4SMHA. Our 139-cc 4-hp portable outboard mirrors our 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.
