The lightest 8 HP build Mercury lists, at 84 lbs, this used 8MH FourStroke pairs a twin-cylinder engine with the short shaft, tiller steering, and manual starting. Coverage on this unit Add it up and coverage reaches five years here: Mercury's regular factory term, with a two-year Product Protection Gold plan stacked above it. Specifications and condition Gearcase ratio sits at 2.08:1 on this carbureted twin, shifting the usual forward-neutral-reverse pattern, and trim adjusts manually across a shallow water range of 16 degrees. This motor shows wear tied to its service history rather than new-in-box condition, though its fuel system and 3-star CARB rating carry over unchanged from new. Running on no more than a 10 percent ethanol blend with Mercury's own FourStroke 10W-30 oil, it ships with a Phantom Black propeller included. Clean the flame arrestor screen periodically to keep idle quality steady. Q: Short shaft or long shaft on this model? Short, built for lower-transom boats. Q: Does starting require a battery? No, this is a manual pull-start motor with no alternator or battery fitted. Q: What's included with this used motor? A Phantom Black propeller, plus Mercury's 10W-30 four-stroke oil recommendation for upkeep. Q: Does this motor have power trim? No, trim here is the ratcheting manual type, adjusted by hand.
