Details & Inspection Notes
This new 2017 Mercury 6 HP 6MH outboard is the earlier model-year version of Mercury's short-shaft portable 6hp line: a 15-inch shaft, manual start, and an integral fuel tank, all in a motor Mercury lists at 57 lbs. A front-mounted gear shift lever and tiller steering keep it simple for small jon boats, skiffs, or a sailboat's auxiliary power.
Model-year specifics
This unit carries SKU 6MH-17, built in Japan. The single cylinder measures 2.32 x 1.77 inches in bore and stroke, with a 2.15:1 gear ratio and full throttle between 5000 and 6000 rpm. Fuel delivery is by carburetor, drawing from the built-in 0.3-gallon tank, about 1.15 liters, and the engine carries a saltwater rating.
Controls and in the box
Trim and tilt adjust manually rather than by switch, shift runs forward-neutral-reverse, and an optional 12-volt, 4-amp, 50-watt alternator installs separately if you want to add battery charging. Mercury ships this motor with its built-in fuel tank, owner's manual, mounting hardware, an aluminum propeller, four-stroke oil, and a tool kit, under a 3-year Mercury warranty.
Does Mercury still sell a newer model year of this engine? The 6MH's core specifications carry over between model years; ask us which year is currently in stock if that matters to your purchase.
Will a propeller for a longer-shaft 6hp Mercury fit this one? No, match the propeller to this 15-inch short-shaft gearcase rather than to a long-shaft model. Mercury outboards
