Mercury 4 HP 4MLH Four-Stroke Outboard, 20" Shaft, Tiller
The Mercury 4MLH is a 4 HP single-cylinder four-stroke outboard with a 20-inch long shaft, tiller throttle and shift, and manual start. It weighs 55 lbs, displaces 85 cc and runs 5,000–6,000 RPM at full throttle.
Exhaust leaves through the propeller for quieter running, and the motor suits aluminum tiller boats, soft-hull inflatables, jon boats, utility boats and sailboats. Trim and tilt are manual and rotation is standard. Included are a 7.4 x 7.0-inch three-blade composite propeller, integrated carry handle, safety lanyard stop switch, 0.3-gallon internal fuel tank, tool kit and owner's manual, in Phantom Black.
