The Yamaha F300A outboard motor is a double overhead-cam 60-degree V8, displacing 5330cc, or 325 cubic inches. Reported dry weight is 373kg, or about 86kg more than the 3.4-liter V6 Yamaha F250. The F300 motor features variable valve timing, ionic combustion sensors, a new anti-corrosion system, massive forged motor mounts and transom bracket, heavy-duty gears and drive shaft made of hardened steel, a special series of propellers, and a new air-intake labyrinth designed to keep water intrusion to a minimum. It is also the first Yamaha outboard to feature a digital drive-by-wire throttle and shift control. Yamaha says the motor's astounding weight is a result of its desire to make the F300 extremely durable, and reliable enough to take far off-shore. Yamaha has simply made every component stout enough to handle the motor's rated thrust as it presses against the transom of a pretty big boat.
