V6 Offshore

A tangerine sunrise alights the shore as you load up the gear for a morning of coastal fishing. Your buddies are rearing to go—as are your twin V6 Offshore outboards. Known for their power, efficiency, and outstanding reliability, Yamaha’s V6 4.2-liter outboards are some of the most trusted V6’s on the water. They’re also some of the nimblest, with integrated digital electric steering. This makes them more responsive than ever. Our V6 Offshore outboards have proven once again that even a trusted favorite can take an exciting turn.

Our 4.2-liter F300 is a reliable, offshore favorite—and it's only getting better. It now features a fresh, new cowling design (with engine-mounted Propeller Indicator Lights if rigged with Helm Master® EX), new integrated digital electric steering*, and rerouted exhaust for enhanced reverse thrust. It’s destined to be a top choice offshore for years to come.

  • Recommended fuel: 89 Octane
  • Shaft lengths available: 25”, 30”, and 35” (30" and 35” on F300 DEC only)
