Yamaha 300 HP DEC F300UCB2 Four-Stroke Outboard, 30" Shaft, White Cowling
The Yamaha F300UCB2 is a new 300 HP six-cylinder four-stroke outboard with a white cowling, a 30-inch (XX-long) shaft and DEC digital controls through Command Link. The 4,169 cc engine is fuel-injected and the motor weighs 562 lbs.
The F300 is aimed at offshore dual and center consoles, walkarounds, runabouts and pontoons, and lets owners move up in horsepower and displacement without re-rigging. This version adds a new cowling design and rerouted exhaust for stronger reverse thrust. Power trim and tilt, the white cowling and the owner's manual are included; the propeller is not.
