THROTTLE RESPONSE AND ACCELERATION
Yamaha's Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase
power and throttle response in the low- and mid-rpm ranges. This feature helps Yamaha's new 4.2 liter big-bore V-6
Offshore Outboard to deliver awesome hole shot and mid-range acceleration you have to feel to believe.
BEST-IN-CLASS FUEL EFFICIENCY
Yamaha's 300hp V6 Offshore outboard has up to 17% better long-range fuel economy at 3500 rpm than other 300hp
4 stroke outboards. All air entering the engine block of each Yamaha V6 Offshore outboard is routed through a single 75mm
electronically-controlled throttle valve. Working in concert with the Precision Multi-Point Fuel Injection System, together
they help ensure the precise amount of air and fuel necessary for optimum power and fuel effi ciency. The reduction in
friction from the Micro-Textured Cylinder Walls further adds to this outboard's amazing fuel economy.
