Mercury Engine Quality
Most rebuilt Mercury engines are just that, rebuilt. Our Mercury remanufacturing line builds to IMPROVE not just REPLACE! All parts in our high quality Mercury performance engines (long blocks, short blocks, big blocks & small blocks) meet or exceed all the Mercury original specifications, and most of the time are purchased from the same suppliers who supply Mercury!
All the moving parts in our Mercury remanufactured engine are NEW. Be cautious of other engine remanufactures using used, broken, re-machined or returned parts!
Due to our precise re-manufacturing standard, the Mercury Engine line has achieved one of the lowest breakdown rates in the world - Below 1.5% breakdown rate
We keep a large inventory of Mercury remanufactured engine blocks mostly for passenger cars, light trucks, pickups and some marine applications. Most of our Mercury engine supply is ready for instant freight.
