About Mercury 8HP 8MH 15″ Shaft – Outboard Motor
The Mercury 8MH is an 8-horsepower FourStroke that moves up to a 208cc twin-cylinder block, the same powerhead behind Mercury’s 9.9, so it runs smoother and quieter than the single-cylinder portables below it. It’s carbureted with a rope start, a twist-grip tiller, a 15-inch short shaft, and a full forward-neutral-reverse gearshift. Fuel feeds from an external tank for real range, and the 88-lb package carries Mercury’s saltwater corrosion protection and sacrificial anodes.
Two cylinders make the difference on a long idle or a slow troll, where a single buzzes and this one just runs, which suits a tin boat or small skiff working the coves along the Maine coast. It’s also honest kicker power for a bigger boat that wants get-home backup offshore. South Port Marine stocks the 8MH in South Portland, so call (207) 799-8191, or the Danvers office at (978) 904-1924 for the North Shore.
