FEATURES
OPTIMIZED CURRENT AND COOLING
A new cowling exhaust port and stator fan keeps everything under the cowling nice and cool, maximizing available net charging power at all RPM, especially in the lower RPM ranges. The cooling effect is impactful enough to create more available current for the new 4.3L V6 F350 over the 4.2L V6 F300 at all RPM.
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.
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.
A new clutch dog design, machined with more teeth, increases torque transfer from powerhead to propeller.
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.
Iridium spark plugs work together with Yamaha’s new fuel injection control mapping to produce a lengthened injector duration for more power.
