Yamaha 300 HP DEC LF300ECB2 Outboard, 35" Shaft, Counter-Rotation, White
The Yamaha LF300ECB2 is a 300 HP six-cylinder four-stroke outboard with counter (left-hand) rotation, a 35-inch (XXX-long) shaft and a white cowling. It uses DEC digital controls through Command Link, a 4,169 cc fuel-injected engine and weighs 562 lbs.
Built for offshore dual and center consoles, walkarounds, runabouts and pontoons, the F300 allows a move up in horsepower and displacement without re-rigging. This version has a new cowling design and rerouted exhaust for stronger reverse thrust. The counter-rotation model comes with power trim and tilt, the white cowling and the owner's manual; the propeller is not included.
