  • 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.
  • Charging Power: Our 4.3L V6 Offshore F350’S 70-Amp Alternator Produces More Than 30 Net Amps Per Outboard At Idle—Nearly Double That Of Yamaha’S Other Comparable Outboards.
  • More Power: Iridium Spark Plugs Work Together With Yamaha’S New Fuel Injection Control Mapping To Produce A Lengthened Injector Duration For More Power.
