Description

6 HP

Our 139-cc 6-hp portable is an impressive little outboard. It boasts surprising features for such a small motor, like labyrinth exhaust and a long span mounting system for smooth, quiet power. It also offers the convenience of an external fuel tank (in addition to its built-in tank) for extended range and added convenience.

  • Only 60 pounds (15” shaft model)
  • Available in 15” and 20” shaft lengths
  • Solid 6-amp alternator (optional)
    • 4 HP

    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.

  • Only 60 pounds (15” shaft model)
  • Available in 15” and 20” shaft lengths
  • Solid 6-amp alternator
    • 2.5 HP

    Our 72-cc 2.5-hp portable outboard is the smallest motor on our roster, but it still packs a punch. Completely redesigned, it’s even more portable, easier to store and clean burning.

  • Only 37 pounds (15” shaft model)
  • Available in 15” and 20” shaft lengths
