Starting with premium Racing engine core, every unit is produced under very strict guidelines and specifications to meet the expectations of the high performance customer. Mercury customers no longer need to send their marine race engines off to an automotive engine rebuilder. Each Racing Series engine is also factory sealed just like the engines from Mercury Racing. Depending upon the model, a high-rise carbureted intake manifold or intake manifold base for an EFI Mercury racing engine is included. Quicksilver Remanufacturing offers Racing Series longblocks from 500 HP to 600 HP for carbureted, fuel-injected and supercharged models
