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 V6 4.2-liter F250 is perfect for offshore dual or center consoles, walkarounds, runabouts, and pontoons. It allows you to step up your horsepower and displacement without rerigging. Only now, it 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 just proves even the best can get even better.

Features may include:

  • Recommended fuel: 87 Octane
  • Shaft lengths available: 25”, 30”, and 35" (30" and 35" on F250 DEC only)
  • Alternator output: Up to 70 amp
