Yamaha 4 hp outboard for sale.

2021 Yamaha Marine F4

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.

Features may include:

  • Tiller-handle control with forward-neutral-reverse shifting and an ergonomic twist-grip throttle
  • Only 59 pounds (15” shaft model)
  • Available in 15” and 20” shaft lengths
  • Solid 6-amp alternator.
