Dark blue water. Miles from land. Nothing but you, your crew and the monsters raring to give you a run for your money. Year after year—your love of the offshore remains unchanged. Your tech on the other hand is always the most advanced—including your outboard. The all-new 4.3L V6 Offshore F350 merges all the best tech from our full line of outboards with some impressive tech of its own. The result is a perfectly balanced, deep breathing V6 that delivers jaw-dropping power and the best power-to-weight in its class—the new, 4.3L V6 Offshore F350.

Weighing in at 629 pounds and delivering an astounding 11:1 compression ratio, the new 4.3L V6 Offshore F350 creates jaw-dropping power in an incredibly light design. In fact, it boasts the best power-to-weight in its class—by more than 65 pounds. Available in Yamaha gray, pearlescent white or new classic white, the 4.3L V6 F350 is the new knockout offshore.

Features may include:
  • Recommended fuel: 89 Octane
  • Shaft lengths available: 25”, 30” and 35”
  • Alternator output: up to 70 amp

Power and Performance

RESPONSIVE POWER
  • It’s center-mounted 81mm electronic throttle valve is eight percent larger than the F300. Flanked by identical port and starboard intake manifolds, it creates a well-balance design, smooth air flow and responsive power.
INCREASED COMBUSTION
  • A camshaft profile with a higher valve lift allows for longer opening duration for intake and exhaust. Combined with reimagined valve lifters, it creates precise clearance for increased combustion.
MAX TORQUE
  • A new clutch dog design, machined with more teeth, increases torque transfer from powerhead to propeller.

Convenience and Control

MORE FUNCTIONALITY / SECURITY
  • Helm Master® EX includes Autopilot with Heading/Course Hold, 10+ automated modes for fishing and relaxing, in-mode joystick adjustability and the expanded ability to control up to five outboards. There’s even an optional theft-deterrent system, Y-COP®, which disables the ignition and fuel systems while docked.
FAST, EASY TILTING
  • Helm Master® EX includes Autopilot with Heading/Course Hold, 10+ automated modes for fishing and relaxing, in-mode joystick adjustability and the expanded ability to control up to five outboards. There’s even an optional theft-deterrent system, Y-COP®, which disables the ignition and fuel systems while docked.
POWERFUL, PRECISE MANEUVERING
  • Thrust Enhancing Reverse Exhaust keeps exhaust bubbles away from the propeller below 2500 RPM and when in reverse. This means the prop bites only clean water, which results in outstanding reverse thrust and control—especially when backing down on fish and when maneuvering around docks.
