Mercury 8EH FourStroke Outboard Motor

At 84 lbs dry — the lightest build Mercury lists in this horsepower category — this used 8EH FourStroke is a twin-cylinder 8 HP four-stroke, short-shafted, tiller-steered, and electric-started.

Coverage on this specific unit

Past the usual Mercury factory term, this specific listing throws in a two-year Product Protection Gold plan, landing at five years of coverage overall.

What the numbers say

Bore and stroke on this twin come in at 2.16 by 1.73 inches, and the gearcase spins a 2.08:1 ratio. A 76-watt, 6-amp alternator handles charging, paired with a 3.2-gallon remote tank. Given its service record, expect wear typical of a motor that has already seen use rather than new condition, though its carbureted fuel system and 3-star CARB rating match a new unit. Trim adjusts by the ratcheting manual method rather than power trim, and a Phantom Black propeller ships with the unit. A snug motor cover reduces cowl fading between outings.
