2025 Yamaha Marine Portables 4 HP

PORTABLES

The harbor is like glass as you board the tender to your cuddy for a day on the water; your trusty Yamaha Portable ushering you out. With easy starts, incredible efficiency and reliable performance, Yamaha’s F6, F4 and F2.5, are perfect for all sorts of light duty. Wherever the day takes you, take along a little extra power with Yamaha’s smallest Portables.

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:

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